## Integration Checklist



 Please ensure that the following items are checked off before release to have a cleaner integration:

* Ensure that correct value is sent for MERCHANT_ID and CLIENT_ID to identify the Merchant.
* Send a unique ORDER_ID to cross-check data with Juspay.
* Please ensure that customer details are already updated on Juspay backend.
* Make sure to pass backpress event onBackPressed and call super.onActivityResult (in case of Fragment based integration).
* Get the final build tested by Juspay's QA team.
