Double-check the algorithm and method used to generate the signature. Refer to the Checkout.com API Authentication Guide for detailed instructions on how to correctly sign your requests.
Ensure that all parameters included in the request are correctly reflected in the signature. Any changes in the request payload should be accounted for in the signature generation process.
Use sample requests provided in the Checkout.com API Reference to test your implementation. This can help identify discrepancies in your signing process.
