3. Verify Transaction
After customer authorization, verify the transaction status:
curl -X GET '{{baseurl}}/transaction/verify/{reference}' \
-H "Authorization: Bearer YOUR_SECRET_KEY"Sample Success Response
{
"status": true,
"message": "Transaction verified successfully",
"data": {
"reference": "COR_202402210123456789",
"amount": "100",
"currency": "NGN",
"status": "success",

}
}⚠️
Always verify the transaction status before confirming payment. The verification step is crucial as the customer might decline or ignore the payment prompt.
