Things to keep in mind!

Supported Flows
Currently, we support only those transaction flows where redirection is expected to lead directly to an OTP screen. Flows involving intermediate steps such as EMI selection or surcharge confirmation are excluded from this support.

Recommended PG Setup
It is preferable for merchants to have more than one active payment gateway (PG) configured. This setup allows us to implement fallback mechanisms in case of PG coverage failures.

Handling Single-PG Setups
For merchants with only one active PG, we recommend relaxing the constraint that order_id = txn_id. This is necessary to enable retries on the same PG in the event of a coverage failure.
