Not every failed payment means the same thing.
During development, it quickly becomes clear that different API responses require completely different handling strategies.
For example:
{ "errorCode": "400.002.02", "errorMessage": "Bad Request - Invalid SecurityCredential"}
and
{ "status": "failed", "result_code": 8006, "result_description": "The security credential is locked." }
Although both requests fail, they represent different production scenarios.
The first indicates that the request could not be authenticated because the supplied SecurityCredential is invalid. The payment workflow never begins.
The second shows that the request reached the provider, but the configured SecurityCredential has been locked, preventing the transaction from being processed.
A reliable payment platform should never classify every response as simply “payment failed.”
Instead, it should:
• log the provider error code and description
• preserve the current transaction state
• prevent unsafe automatic retries
• notify the operator when manual intervention is required
Proper error handling is just as important as successfully sending a payment. In production payment systems, understanding why a request failed is essential for maintaining transaction integrity and building reliable automation.
I recently documented several real-world Daraja API integration scenarios, including authentication failures, callback processing, retry strategies, duplicate protection, and production architecture:
