Hello Visa Developer Community,

}
}

I've already tried the following:
1. Double-checked my API credentials
2. Verified my SSL certificate is valid and properly configured in Postman
3. Confirmed I'm using the correct sandbox API endpoint

Can anyone provide guidance on how to resolve this token validation error? Are there any specific troubleshooting steps I should take for error code 9210?

Thank you in advance for your help!

Hey @admin_11,

Here are the possible solutions and troubleshooting steps:

1. Check the Certificate Chain: Ensure that the entire certificate chain is properly configured and that the root and intermediate certificates are included in the SSL setup.

2. Verify the KeyID: Make sure that the keyID in your request headers matches the key associated with your certificate.

3. Ensure Correct Encoding: Double-check that your Base64 encoded credentials in the Authorization header are correctly encoded. It should be in the format Base64Encode(username:password).

4. Check encData Formatting: Ensure that the encData is correctly formatted and encrypted as expected by the API.

5. API Key and App ID: Verify that your X-App-Id and other API keys are correct and are not expired or revoked.

6. Postman Configuration:

   • In Postman, ensure that the client certificate is correctly configured under the "Settings" -> "Certificates" section.
   • Ensure that Two-way SSL is properly set up and that both the client certificate and private key are correctly added.

7. Sandbox Environment: Confirm that you are using the right endpoint for the sandbox environment, which you seem to have already done.
