Troubleshooting

1. Invalid API Key or Inactive Merchant:

- Ensure that you are using the correct API key provided by OxaPay for authentication and authorization.

- Check if your merchant account is active and enabled for API access. If not, contact OxaPay support to resolve the issue.

2. Validating Problem:

- Verify that all required parameters are included in the request and have the correct format.

- Check for any misspelled parameters or incorrect values that might cause validation errors.

3. Invalid Callback URL:

- Ensure that the provided callback URL is a valid and accessible HTTPS URL where OxaPay can send payment notifications.

- Double-check for any typos or missing characters in the callback URL.

4. Invalid Return URL or Failure URL:

- When specifying return URLs or failure URLs, make sure they are valid URLs where the payer will be redirected after a successful or failed payment, respectively.

- Confirm that the URLs are correctly formatted and accessible.

5. Insufficient Balance or Transfer Limits:

- If you encounter errors related to insufficient balance or transfer limits, ensure that your merchant account has sufficient balance to process the payments.

- Verify that the payment amount is within the allowed transfer limits set by OxaPay.

6. Payment Status Not Updated:

- If you do not receive payment status updates or callbacks, check your server's firewall settings to ensure that OxaPay's requests can come through.

- Make sure that your server is accessible over HTTPS to receive callback notifications.

7. Incorrect Currency or Network:

- Ensure that you are using valid currency symbols and network values when making API requests.

- Refer to the documentation or supported currencies/networks endpoint to get the correct values.

8. Rate Limit Exceeded:

- OxaPay has rate limits in place to prevent abuse of the API. If you receive a rate limit error, consider optimizing your API usage or contact OxaPay support for assistance.

9. Callback Signature Validation:

- When receiving webhook notifications, validate the signature of callbacks coming from OxaPay using your API Secret Key. This helps prevent fraudulent activity.

- Check that the HMAC signature in the HTTP header matches the signature generated from the raw POST data using the API Secret Key.
