Initialisation

You can perform user verification via Truecaller at any touchpoint in your journey (for example - login, registration, checkout, verification, etc.).
To initiate the user verification, you need to trigger a deep link upon any user action, in the format mentioned below :
truecallersdk://truesdk/web_verify?type=btmsheet
&requestNonce=UNIQUE_REQUEST_ID
&partnerKey=YOUR_APP_KEY
&partnerName=YOUR_APP_NAME
&lang=LANGUAGE_LOCALE
&privacyUrl=LINK_TO_YOUR_PRIVACY_PAGE
&termsUrl=LINK_TO_YOUR_TERMS_PAGE
&loginPrefix=TITLE_STRING_PREFIX
&loginSuffix=TITLE_STRING_SUFFIX
&ctaPrefix=BUTTON_TEXT_PREFIX
&ctaColor=BUTTON_FILL_COLOR
&ctaTextColor=BUTTON_TEXT_COLOR
&btnShape=BUTTON_SHAPE
&skipOption=FOOTER_CTA_STRING
Here, requestNonce should be a unique request ID that you need to associate with every verification request you trigger, so as to do the requisite mapping of the access token which we post to your callback URL once users share their consent.
NOTE : The minimum length of the request ID parameter should be 8 characters and maximum length can be 64 characters
Add the app key which you generated from your developer portal account in the partnerKey parameter, and the app name that you want users to see in the Truecaller profile dialog in the partnerName parameter.
