Hello and thank you for reaching out! This may in fact be out of our scope, but we will do our best to give this a shot! We did some searching and found the following troubleshooting steps in a Printful article titled “What are the most common WooCommerce and WordPress errors and how to resolve them?” I would recommend taking a look to ensure you have covered everything they recommend.
“This error may be caused by a misconfiguration of your WordPress server (status code 403). 403 means that your web server is refusing access to certain URLs.
How to troubleshoot it?
Check if your server allows access to the following endpoints and all subdirectories:
Other possible causes:
- The server configuration is stripping off Basic Authentication Headers.??
- One of the installed plugins modifies the standard WordPress/WooCommerce API authentication.??
- The PHP-FPM module is causing authentication issues.???
How to troubleshoot it?
There can be multiple reasons for this error, but most of them are happening on the server side.
The first step is to check the server access logs that contain information about the 403 requests. If you don’t know how to do it or can’t access server logs, contact your hosting provider, explain the issue in detail, and ask them to troubleshoot the issue.”
Regarding the endpoints and all subdirectories, you can check if these are working, and if API is enabled by adding /wc-api/v1/ to the end of your domain and then enter that into a browser. If you see code similar to what is seen here, https://www.woothemes.com/wc-api/v1, then that part should be OK.
Another idea would be disabling all of the plugins in your WordPress website except Printful and WooCommerce before trying to finish the integration between the two. That should help eliminate a lot of variables and may allow them to connect. Be sure to reactivate the plugins that were disabled when you are done to ensure your website looks and feels correct. When you are enabling the plugins, be sure to do so one at a time and while checking Woocommerce and Printful plugins for issues. If one of the plugins that you are using is causing the error, you should be able to determine which one with this method.
We do hope this helps and if you need additional help with this please, feel free to reach out to us on Facebook or Twitter/X so we can take a closer look, we would appreciate more information on this as there are quite a few things that could be causing the error message that you are seeing.
