Explanation:
A 403 forbidden error can be caused by a number of factors related to the host service or other restrictions. Below are a few instances that may cause a 403 forbidden error and the recommended solution.
Please ensure you reach out to your developer for troubleshooting.
Action:
-
Permission Issues
- Cause: The API credentials used for Afterpay may lack the necessary permissions, or the WooCommerce user role does not have sufficient privileges to update plugin settings.
-
Resolution: Ensure that the API user has the correct permissions and that the WooCommerce user role has administrative access to modify plugin settings.
-
Security or Firewall Restrictions
- Cause: Web Application Firewalls (WAF), mod_security rules, or hosting security settings may block Afterpay API requests.
-
Resolution: Check the server firewall settings and whitelist Afterpay’s API endpoints to allow external API requests.
-
Incorrect API Credentials
- Cause: If the API key or merchant credentials are invalid, the Afterpay server may reject requests with a 403 error.
- Resolution: Verify that the Merchant ID and Secret Key are correctly entered in the Afterpay plugin settings.
-
IP Whitelisting Required
- Cause: Some hosting providers require whitelisting of specific IP addresses to access external services. If the hosting provider has changed, the new IP may not be authorized.
-
Resolution: Confirm that the current server IP is authorized to make API requests.
-
Caching or CDN Conflicts
- Cause: Some CDN services (e.g., Cloudflare, Fastly) or server-side caching may block or interfere with API requests.
-
Resolution: Disable the CDN temporarily or clear the server cache to resolve potential conflicts.
-
Outdated Plugin or API Changes
- Cause: An outdated Afterpay plugin may not be compatible with the latest API updates.
-
Resolution: Ensure the Afterpay plugin and WooCommerce are updated to the latest versions.
-
Rate Limiting or Blocked Requests
- Cause: If too many API requests are made within a short period, access may be temporarily blocked.
- Resolution: Wait before attempting another request to avoid rate limits.
