post https://api.cashfree.com/api/v2/subscriptions/seamless/authorization
Use this API to create an authorisation request for a particular subscription. This API is applicable only if you have created a subscription via Create Seamless Subscription API. Use the response of the Create Seamless Subscription API to get the supported banks for E_MANDATE and supported UPI handles.
A POST redirection should be made to authPaymentData.link with authPaymentData.postData. However, in the test environment, the response for Create Auth is just dummy data and not actual bank links. So after creating auth in test env, use the Simulate Update Auth endpoint to update the status of that authorization. POST redirection is not supported in the test environment.
TPV is currently not supported for UPI Intent/Qr auth flow.
