Integration

The integration of this SDK is very straight forward.

1) Inside any HTML page just import the Javascript library before the </body> tag

<script src="https://api.andia.io/web/andiaSdk2.0.min.js"></script>

2) Include the following HTML fragment, to add a button

<div id="containerAndia"></div>
<button id="andiaBtn" type="button"
            class="btnAndia"
            customerId="YOUR_CUSTOMER_API_KEY"
            face_id=""
            action="onboarding"
            callback="YOUR_CALLBACK_URL" >
     <div id="labelBtn">Onboard me</div>
</button>

Parameters

customerID . Your customer API_KEY , mandatory (we provide these credentials)

face_id Mandatory in the Validation process, this face_id is returned in the Onboarding of a specific User. Then when a Selfie validation is required, this is the way to validate a user against her face_id. This parameter is empty when we call an Onboarding a new user.

callback Mandatory: Your “callback URL”, with a unique ID to identify the user’s transaction in the response.

action Mandatory: "onboarding" or "validate"

onboarding   Perform a new user Selfie Onboarding and get the face_id of this new user.
validate     Perform a selfie validation, of an existing user (with an existing face_id), previuosly onboarded. Call this method on Password Recovery, validate transactions, or verify that the user is on front of the webcam.  

3) Callback

To get the result of the Selfie Validation or the Selfie Onboarding, just implement a POST data endpoint.

Response parameters

success . Boolean, true if the Selfie was made successful

data A Form Data object with the following fields.
