Authorization

Fetch Auth Token API

Merchant backend should call this API to get an auth token, which will be used to authorize the subsequent API calls between the Merchant & PhonePe backend.

The generated token can be used to make multiple API calls until it expires.
Merchant can save the token and rely on the “expires_at” field for the expiry of the token, within which the token should be refreshed by using the same API.
