Check Transfer

Overview

Validate transfer details before executing a money transfer. This endpoint validates all transfer parameters and returns the foreign exchange (FX) rate for the corridor without actually sending money.

Best Practice: Always call this endpoint before executing a transfer to validate the transaction and get the current FX rate for the transfer.

Important: approvelyId AttributeIf you’re using the Payout API with our Payin API, you must include the approvelyId attribute to link the payout with the payin transaction:

{
  "name": "approvelyId",
  "value": "46364493"
}

Without this attribute, the transaction will be created but will wait for automated/manual reconciliation checking, which may cause delays.

Validation Checks

Best Practices

Always check before transfer

Call this endpoint before every transfer to validate parameters and check receiver status.
