Error Handling
After submitting an API call to OPay, you receive a response back to inform you that
your request was received and processed. A successful OPay API should return a status code 00,
meanwhile, in a situation where any payment processing error occurred, you will receive an error code with a
message to describe the reason of the error. A sample error response can be found below.
{
"code": "05057",
"message": "The agreementId already exists."
}
Depending on the HTTP status code of the response, you should build some logic to handle any errors that a request or the system may return. A list of possible potential error codes that you may receive can be found below. A full list of all possible error codes can be found in the Error Codes section.
