# Get Transaction Info

Retrieve the authoritative status of a pay-in or pay-out transaction. Use these endpoints alongside webhooks to confirm final outcomes — never rely on redirects or client-side events. For test transactions, `merchantPspId` (pay-in) / `processorPspId` (pay-out) equals the fake PSP ID provided by OMNO; do not credit or debit real balances for those.

 - [GET /public/payout/{payoutId}](https://docs.omno.com/apis/payments/openapi/get-transaction-info/fetchpayouttransaction.md): Returns the payout transaction for the given ID. This is the authoritative status check for a payout, used alongside webhooks. Never rely on redirects or client-side events for the final status.
 - [GET /public/payin/{payinId}](https://docs.omno.com/apis/payments/openapi/get-transaction-info/fetchpayintransaction.md): Returns the pay-in transaction for the given ID. This is the authoritative status check for a pay-in, used alongside webhooks. Never rely on redirects or client-side events for the final status.
