What is Collect Call?
Merchant can send a notification to the customer's PhonePe app using this flow. If the customer has not installed the PhonePe’s app then he will receive an SMS with the link to download the app and then complete the transaction
What is the expireIn parameter?
ExpiresIn is the expiry time till the customer can make the payment. If the customer does not respond within this time then the request expires.
The value should be in seconds and generally, 180 sec is passed in this parameter. If no value is passed in this parameter then, by default, the request is valid for 30 days.
What is the transactionId parameter?
A unique value is passed in this parameter in order to track the transaction at the later stages. Values should be alpha-numeric and without any spaces and should contain less than 38 characters. If a value is passed which is already stored in the PhonePe server then the server will give you 417-expectation error response code (INVALID_TRANSACTION_ID, msg: duplicate transaction id).
What is Check Payment Status API?
It is used to get the current state of any transaction with the help of transactionId
Do we need to use Check Payment Status API to get the status of the transaction if we have already passed x-callback-URL to get the callback from the PhonePe server?
Yes. It is used as a fallback option and it gives the current status of the transaction even if it is in a non-final state (ex. PAYMENT_PENDING).
What is the difference between PAYMENT_ERROR and INTERNAL_SERVER_ERROR?
**PAYMENT_ERROR - It is the final state of the transaction. It simply means that payment is failed and the cashier can initiate a new transaction and ask the customer to try again. No waiting period to mark the transaction as failed
** It is a non-final state of the transaction. In this scenario, the cashier need to wait until he gets any final state of the transaction (i.e. PAYMENT_SUCCESS or PAYMENT_ERROR). The Cashier can use Check-Payment-Status API in order to get the current status. The cashier needs to wait a max time period up to the time passed in expiresIn parameter during making the payment request.
What if the customer does not respond to the payment request?
The payment request will expire as it reaches the time period passed in the expiresIn parameter during the call of the respective APIs. And if we check the current status of the transaction then it must be PAYMENT_ERROR
