Get Transaction Status Basic

This API allows the platform to fetch the status of a transaction intiated through a payment link/collect request/dynamic QR code.


Important Note

Please use only Staging Credentials on each API Reference page to test the APIs directly from our Documentation.


This API allows a platform to fetch the status of a transaction undertaken through any of the flows below.

Note: this API doesn't allow the platform to check the status of a transaction like a push transaction or a static QR.


This API is an alternative to the Terminal Transaction Status Callback/Webhook. The platform should use this only if a callback hasn't been acknowledged or transaction confirmation hasn't been received.

  1. The platform consumes this API to get the latest status of an initiated transaction using the Decentro transaction ID received from Generate payment link API, Generate Dynamic QR.
  2. In this API, Decentro relays the transaction status via the transaction_status field. The default status will always be 'PENDING' unless the payer authorizes a payment.
  3. In case multi attempt is enabled, checking the payment status will return the payment link status (SUCCESS, PENDING, EXPIRED).
  4. In case multi attempt is disabled, checking the payment status will return the payment link status (SUCCESS, PENDING, FAILED, EXPIRED).

To know the status of each attempt made by the payer, client can consume GTS advance.
