CurrentStatusV3
The CurrentStatusV3
object is the sole return type of all the web methods in the API. It is intended to provide information about what has just happened, as well as giving an overview of the person’s current verification status, and the list of data sources that will help the person become fully verified. Always presenting this information helps to reduce the chattiness between greenID and the customer application.
Name | Type | Description |
---|---|---|
| This member contains a list of | |
| This member contains all of the verification information currently available for a person. It is a complete record of all checks that have been performed, their results, and an indicator of the person’s overall verification status. | |
| This member contains a list of fields that are required for a particular data source. This includes the field’s name, type and other pertinent information for displaying and collecting a value for the field. | |
checkResult | LastCheckResultV3 | This member indicates the outcome of a check against a data source that was performed during a call to the setFields web method. This member also indicates whether the check is still in progress. |
verificationToken | String | This field is for future features in the API, and can be ignored for now. |
LastCheckResultV3
The LastCheckResultV3
object is intended to give a snapshot of the status of a check that has been performed during a call to the setFields
web method.
Name | Type | Description |
---|---|---|

|
| This member indicates whether this source has been passed, i.e. the check is in one of the verified states. |
|
| This member is the name of the data source. This name is expected to be used to refer to this data source in calls to the |
available | boolean | This member indicates whether this data source is currently available; sometimes a particular data source may not be available. |
notRequired | boolean | This member indicates whether this data source can help a person become fully verified. If the value is true , then there is no point using this data source because it cannot help the person become fully verified. |
oneSourceLeft | boolean | This member indicates whether completing this data source will make a person fully verified. This member is very valuable because it indicates which sources should be attempted first, thereby shortening the verification process. |
order | int | The order in which the source would be displayed if it were being displayed by greenID. Sources that are more likely to result in the person becoming fully verified are at the top of the list, i.e. their “order” number is lower. |
attributes |
| This member contains a list of HTML attributes that should be applied to any HTML input collecting input from a person. For example, the HTML attribute “class=’required’” would be represented by a NameValuePair with name=”class” and value=”required” . |
SourceFieldsV3
Name | Type | Description |
---|---|---|
| This member contains a list of fields that are required for a particular data source. The members of list represent HTML fields for collecting input from the person. | |
rawData | String | This member contains an HTML fragment that, if displayed, will present HTML fields for collecting data from a person in order to perform a check against a data source. Some customer may prefer this approach rather than generating their own HTML from the data contained in the fieldList member. |
FieldListV3
FieldV3
Name | Type | Description |
---|---|---|
|
| The type of HTML input that is required (at least strongly suggested) for collecting the data for this field from the person. For example, a value of “text” would indicate a simple HTML text input is appropriate. |
|
| The name of the HTML input that would collect data for this field from the person. The name also indicates what the data field is, for example, the value “aec_givenname” indicates the field holds the given name for the AEC data source. |

DateOfBirth
This type is a convenience type for holding a partial date, especially useful for representing dates of birth. This type holds just the date part, and does not contain any reference to a time component or timezone; this avoids potential issues with date of birth timestamps arising from different timezones.
Name | Type | Description |
---|---|---|
|
| The day component of a date of birth. |

Address
The Address
object is intended to serve as a container for address information for countries with a variety of different address schemes and formats. The fields that are present or required will depend on the country that is specified. Similarly, fields may have different validation rules depending on the country, for example, the field "postcode" must be a four digit string for an Australian address, but it must be a five digit string for a US address. For requirements for individual countries, please refer to Address Handling or contact greenID.

VerificationResultV3
The VerificationResultV3
type describes the person’s verification results to date. This is always returned so that the caller always has the latest results for that person.
Name | Type | Description |
---|---|---|
|
| This member indicates the outcome of the entire verification process. Refer to the Reference Table for Overall Outcome States for values. |
ruleId | String | The identifier for the rule that was used to determine the verification outcome. |
mode | String | This member indicates the verification mode that was used. The mode is null , except in the following cases:
|
dateVerified | String | The date this person became verified (null if they have not yet been verified). |
individualResults | List<CheckResultV3> | This member holds a list of results for the individual checks that have been performed to date. |
verificationID | String | The unique identifier for this verification attempt. |
CheckResultV3
The CheckResultV3
type contains all the details of a check against a particular data source.
Name | Type | Description |
---|---|---|
|
| The name of the check. For example, if a check against the Electoral Roll was attempted, then the name would be “AEC”. As each customer will accept a different set of checks, customers should refer to their individual rules document for the list of names that they can expect. Refer to Data Source Reference for a list of data source names. |
|
| The state of the individual check. For a list of possible states, please see the Reference Table of Individual Source States. |
|
| The method via which the check was carried out. This is an enumerated type, for a list of possible values, please see the Reference Table of Method Names. |
mode | String | The verification mode used for this specific check. This shows HOW the check was made. Please see the Reference Table of possible modes. This can be null which indicates that no mode was used. |
dateVerified | String | The date that this particular check became verified (or null if the check is not verified). The string will be formatted in the ISO 8601 format. The pattern used to generate this string in Java is yyyy-MM-dd'T'HH:mm:ss.SSSZ . |
fieldResult |
| Only the fields that were successfully checked, or were changed, are returned. Any field that was not checked is not returned. Note that this may mean the list is empty. |
postOfficeData | PostOfficeDataV3 | If and only if the name of the CheckResultV3 is “PostOffice” then this member will be present. Otherwise it will be null. This represents the raw data retrieved from Australia Post. |
extraData | List<NameValuePair> | Any extra data associated with this check. |
individualResult | List<CheckResultV3> | A list of nested
These elements are discussed in detail below. |
documentType | String | The category the document belongs to. Common values are:
Extra document types will be used as necessary, and if they apply to you, greenID will provide details about the appropriate values. |
documentRegion | String | The region or country the document is associated with. The ISO alpha2 country designation is used. |
documentSubRegion | String | Some document depend on the state or region within the country that issued them. For example, in Australia, each state issues their own driver's licences, so the state must be included to accurately identify the ID document. |
faceMatchScore | String | A string representation of a number that reflects the confidence score that the selfie matches the image extracted from the ID document. The range of valid numbers is 0 to 100. |
Combination sources, as the name suggests, combine multiple things into a single source. Combination sources are used when the greenID Mobile SDK captures an identity document for verification. A combination source will always have the following three components present:
- document authenticity - this component represents the outcome of the automated authenticity and integrity checks that are performed on the image of the document to ensure it is an authentic document, and has not been subject to digital tampering.
- data extraction - this component represents the data that was automatically extracted from the card, and how it relates to the data that the person confirmed.
- document registration match - this component represents the comparison between the details that the person confirmed and the master record.
An example of an XML snippet for the document authenticity component is below, showing an Australian ACT driver's licence that was deemed authentic, indicated by the VERIFIED state:
<individualResult> <documentRegion>AU</documentRegion> <documentSubRegion>ACT</documentSubRegion> <documentType>DRIVERS_LICENCE</documentType> <method>interactive</method> <name>Document Authenticity</name> <state>VERIFIED</state> </individualResult>
Components initially in a pending state have the option of being reviewed; during this process the administrator is required to give a comment on the review. These comments can be returned in the API if configured. The XML captures the comment, the date and time it was made, and the email address of the administrator making the change. An example of the XML that was verified by an administrator is seen below:
<individualResult> <dateVerified>2018-12-04T10:31:28.440+1000</dateVerified> <fieldResult> <data>Ive uploaded a picture of a big beer can</data> <extraData> <name>Date</name> <value>2018-12-04 10:31:28.44</value> </extraData> <extraData> <name>AdminEmail</name> <value>admin@edentiti.com</value> </extraData> <name>AdminComment</name> </fieldResult> <method>interactive</method> <name>Telephone Bill</name> <state>VERIFIED_ADMIN</state> </individualResult>
When a document image is captured by the greenID Mobile SDK, the person has the chance to review the data that was automatically extracted from the image to correct any errors that the OCR process might have made. The results of the OCR process and the so-called "confirmed data" are compared to see how well the OCR process performed, and how many changes the person had to make. If no changes were made, then the data extraction component will be in the VERIFIED state, as in the example below:
<individualResult> <fieldResult> <name>GovId</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>documentNumber</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>dob</name> <status>CONFIRMED</status> <value>1976-04-01</value> </fieldResult> <fieldResult> <name>surname</name> <status>CONFIRMED</status> <value>Smith</value> </fieldResult> <fieldResult> <name>givenName</name> <status>CONFIRMED</status> <value>John</value> </fieldResult> <method>interactive</method> <name>Data Extraction</name> <state>VERIFIED</state> </individualResult>
The comparison between the data that was read during OCR and the confirmed data is subject to the greenID controlled changes process. If the changed made by the person are automatically accepted by the controlled changes process, then the data extraction component can have the VERIFIED_WITH_CHANGES state. If the changes are too large, then the data extraction component can be in the PENDING state, as in the example below where the person changed their surname:
<individualResult> <fieldResult> <name>GovId</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>documentNumber</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>dob</name> <status>CONFIRMED</status> <value>1976-04-01</value> </fieldResult> <fieldResult> <changedValue>Jones</changedValue> <extractedValue>Smith</extractedValue> <name>surname</name> <status>CHANGED</status> </fieldResult> <fieldResult> <name>givenName</name> <status>CONFIRMED</status> <value>John</value> </fieldResult> <method>interactive</method> <name>Data Extraction</name> <state>PENDING</state> </individualResult>
As with regular data sources in greenID, a comparison is made between the data used to check the data source and the master record. Combination sources are the same in this regard. When a person confirms the details extracted from their ID document, with or without changes, the "confirmed data" is compared to the master record, and the changes are subject to the greenID controlled changes process. (The confirmed data may also be used with an external data source, depending on customer account configuration.) The document registration match component reflects this comparison. The XML snippet below shows a document registration match component where no data was changed by the person during the confirmation step:
<individualResult> <dateVerified>2017-01-19T11:37:11.796+0000</dateVerified> <fieldResult> <name>documentScan</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>face</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>dob</name> <status>CONFIRMED</status> <value>1976-04-01</value> </fieldResult> <fieldResult> <name>givenName</name> <status>CONFIRMED</status> <value>John</value> </fieldResult> <fieldResult> <name>surname</name> <status>CONFIRMED</status> <value>Smith</value> </fieldResult> <method>interactive</method> <name>Document Registration Match</name> <state>VERIFIED</state> </individualResult>
Of course, the person may make changes during the confirmation step, and if these changes are too large, the document registration match component can be in the PENDING state, as in the example below where the person changed their surname:
<individualResult> <fieldResult> <name>documentScan</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>face</name> <status>CONFIRMED</status> <value/> </fieldResult> <fieldResult> <name>dob</name> <status>CONFIRMED</status> <value>1976-04-01</value> </fieldResult> <fieldResult> <name>givenName</name> <status>CONFIRMED</status> <value>John</value> </fieldResult> <fieldResult> <changedValue>Jones</changedValue> <masterRecordValue>Smith</masterRecordValue> <name>surname</name> <status>CHANGED</status> </fieldResult> <method>interactive</method> <name>Document Registration Match</name> <state>PENDING</state> </individualResult>
There are two more components to a combination source that may appear, depending on customer account configuration:
- data source - an external data source that can verify the data read from the document, for example, the government department that issues passports.
- face comparison - a comparison between the image of a person extracted from an identity document, such as a passport, and a live selfie of the person captured by the greenID Mobile SDK.
If the data source element is present, then the name of the data source and state of the check will be present, for example, the snippet below shows the data source associated with Australian passports was checked and passed:
<individualResult> <method>interactive</method> <name>PassportDVS</name> <state>VERIFIED</state> </individualResult>
The face comparison component will only be present if face comparisons are configured on the customer's account. If present, the face match score and the state of the face comparison will be present, for example:
<individualResult> <faceMatchScore>55</faceMatchScore> <method>interactive</method> <name>Face Comparison</name> <state>VERIFIED</state> </individualResult>
FieldResultV3
Name | Type | Description |
---|---|---|
addressType | String | Either currentAddress or previousAddress , depending on whether the address was nominated as their current or previous residential address at registration time. This field will only be present for fields that are address related fields. |
|
| The name of the field. The possible name will depend on the source used. Again which sources used will depend on the individual customer setup, and new sources, with potentially new fields are constantly being added. For a list of possible field names for each source, please refer to the Data Source Reference tables. |
|
| This member indicates the status of the field. Refer to the Reference Table for Field Status for possible values. |
value | String | This member contains the original data that was supplied the time of registration, or the “master record”. In the case of a status of ADDITION (see the Reference Table of Field Status) then this will hold the added data. |
extraData | List<NameValuePair> | Any extra data associated with this check. |
format | String | This member indicates the format of the data in this field. This field will only be present for fields that are encrypted, in which case it will have the value PGPEncrypted . |
masterRecordValue | String | This member is reserved for use with combination sources. It's use is discussed below. |
changedValue | String | This member will contain changed values. That is, if a value was changed in order to become verified, then this member will contain the value that the data was changed to, and subsequently verified. |
extractedValue | String | This member is reserved for use with combination sources. It's use is discussed below. |
Regular data sources will have a list of FieldResultV3
elements that have the following elements populated:
name
status
value
- if the value of the field was not changed for use with this data source.changedValue
- if the value of the field was changed for use with this data source, then thevalue
field will not be present. Instead, thechangedValue
field will be present, and will contain the value that was used with this data source.masterRecordValue
- if the value of the field was changed for use with this data source, then themasterRecordValue
is included to explicitly show the change that was made. ThemasterRecordValue
field shows the value of the field from the master record, i.e. the value that was used when registering this verification attempt with greenID.
To illustrate the use of the value
, changedValue
and masterRecordValue
elements, consider an example where the DoB field was not changed with respect to the master record. The DoB field would be represented by the XML snippet below:
<fieldResult> <name>dob</name> <status>CONFIRMED</status> <value>1976-04-26</value> </fieldResult>
Now consider that the DoB was changed from 1/1/1980 on the master record to 1/4/1976 when using the data source, then the following XML snippet would be present:
<fieldResult> <changedValue>1976-04-01</changedValue> <masterRecordValue>1980-01-01</masterRecordValue> <name>dob</name> <status>CHANGED</status> </fieldResult>
This scheme makes explicit every change that was made between the data used for the data source, and the master record.
The scheme becomes a little more complicated when combination sources are used. For a discussion of when the various elements of a combination source, please refer to the previous section about the CheckResultV3
type. The main thing to note in this section is which elements of the FieldResultV3 type are present in the different components comprising a combination source.
In the data extraction component of a combination source, the value
field will be present if the status
field has the value CONFIRMED
, as in the example below.
<fieldResult> <name>surname</name> <status>CONFIRMED</status> <value>Smith</value> </fieldResult>
If the value has been changed, and the status
field has the value CHANGED
, then the changedValue
element will hold the value that the person altered, and the extractedValue
element will contain the value that was automatically read from the ID document. For example, the XML below shows the FieldResultV3
element when a person has changed the value that was read from the card from "Smith" to the value "Jones":
<fieldResult> <changedValue>Jones</changedValue> <extractedValue>Smith</extractedValue> <name>surname</name> <status>CHANGED</status> </fieldResult>
In the document registration match component of a combination source, the value
field will be present if the status
field has the value CONFIRMED
, as in the example below:
<fieldResult> <name>surname</name> <status>CONFIRMED</status> <value>Smith</value> </fieldResult>
If the value has been changed, and the status field has the value CHANGED
, then the changedValue
element will hold the value value that the person altered, and the masterRecordValue
element will contain the value that is associated with the master record. For example, the XML below shows the FieldResultV3
element when a person has a master record where their surname is recorded as "Smith", and the combination source has the surname "Jones" (the value could be different because the person used an identity document with the surname "Jones" on it, or changed the value to "Jones" when asked to confirm the data automatically read from the card):
<fieldResult> <changedValue>Jones</changedValue> <masterRecordValue>Smith</masterRecordValue> <name>surname</name> <status>CHANGED</status> </fieldResult>
