Overview
The greenID Native Mobile Toolkit is an iOS and Android framework that allows a high quality identity verification process to be embedded into mobile and tablet applications.
...
This document describes aspects of the greenID Mobile Toolkit, how to install it, how to use it, and all configuration variables. This document contains some sample code to get you started as well.
Supported Platforms
The GreenID Mobile SDK is available for:
- iOS 9 and above, with iPhone 5 and above;
- Android Lollipop 5.0 (API 21) or above.
Size implications
- For iOS and Android, you can expect your application's compiled size to grow by 30-40Mb
Requirements
In addition to the platform specific requirements below, the following must be in place before you can start using the greenID Mobile SDK:
- You must have a greenID account. If you do not have one, or aren't sure, please contact your greenID representative to check.
- You must have greenID credentials. The credentials comprise an "accountId" and "apiCode", which will be issued to you once your greenID account has been created and activated.
iOS Requirements
- iOS 9 and above
- iPhone 5 and above
- GreenID SDK zip file with all supporting files
- Xcode 8 or 9
Android Requirements
- Android Studio V2.x or 3.x
- A project that targets devices using Android Lollipop 5.0 (API 21) or above
- GreenID SDK zip file with all supporting files

A typical vanilla verification session follows this basic flow:
...
There are only two contact points your application has with the SDK: initialisation and handoff. The SDK handles the rest of the on-boarding and identity verification process.
Returning User Mode
The process described in the previous section applies to the "on-boarding" mode of greenID Mobile. In on-boarding mode, a new verification attempt is registered with greenID every time a person begins the process. However, verification attempts may be registered with greenID via another channel, such as a web service call, and the person can pick up the process on a mobile device for the purpose of photographing an ID document. This is referred to as "returning user" mode.
...
Using "returning user" mode requires the use of a verification token. It is recommended that your native mobile application makes a call to your back end, which in turn makes a call to greenID to fetch a verification token. This is the most secure option. For details on how to fetch a verification token, please refer to the getVerificationToken web service.

After the verification process is complete, the outcome must be securely queried from greenID.
RESTful Web Service
The simplest way to query the outcome is to use the RESTful web service provided by greenID. The web service can be invoked by performing a HTTP GET against the base URL being used plus “/df/verificationResult” with the following query parameters:
...
The web service will return a JSON fragment with all the details of the person and the overall status of the verification attempt. See Old Verification Result Variables for a list of the variables and explanations for each of them.
WSDL Web Service
Whilst using our RESTful webservice is the easiest method to intergate for simple intergrations, it does not return as much detail about a the verification attempt. If your usage senario requires more detail you may need to intergrate using our greenID API web service. Information on how to intergrate using greenID API in general is avalible on the Version 3 greenID API page. For information on how to get the results for a verification attempt made through the GreenID Mobile SDK please take a look at the GetVerificationResult section of the Web Method Details V3 page.
Accessing Image and OCR information for greenID Mobile
For information on how to get the raw and confirmed OCR data back after the verificaiton process as well as document images please refer to the Old Accessing Image and OCR information page.
Styling the screens
The SDK is predominantly made up of HTML/CSS pages served via native web views. You can use the customCssPath parameter to pass in a URL that points to a CSS file residing on your server. This CSS file can include overrides to any of the default style rules so that the screens can adhere to your own branding requirements.
