What steps can I take to resolve the '403 Forbidden' error when linking WordPress with Zapier?

I am attempting to establish a connection between WordPress and Zapier using the Zapier application, but I encounter a ‘403 Forbidden’ error. To address this, I’ve made several adjustments to my Nginx configuration file as shown below:

location = /xmlrpc.php {
    # Begin IP allowances
    include zapier_ips;
    # End IP allowances
    deny all;
    access_log off;
    log_not_found off;
}

In the ‘zapier_ips.conf’ file, I allowed specific Zapier IP addresses like so:

allow 23.20.0.0/14;
allow 34.192.0.0/12;
allow 34.224.0.0/12;
allow 35.153.0.0/16;
allow 35.168.0.0/13;
allow 50.16.0.0/15;
allow 50.19.0.0/16;
allow 52.0.0.0/15;

I would greatly appreciate any assistance in resolving this issue. Thank you!

In my experience, this error might be due to server-level restrictions. Besides adjusting your Nginx settings, you might want to check your firewall rules. Some server-level firewalls might block certain IP addresses even if Nginx allows them. You should also ensure that your WordPress site doesn’t have security plugins limiting access to the xmlrpc.php file. Another thing I’d pay attention to is any CDN or security solutions, like Cloudflare, which might have additional restrictions in place. Verifying that these aspects are configured correctly should lead you in the right direction.

ahh, the infamous 403! you should check if there’s a plugin blocking xmlrpc. some security plugins come pre-loaded to block xmlrpc due to security concerns. Disable them temporarily to test the connection. revert changes only if it’s safe after the test.
