Hey everyone,

I’m having trouble connecting my WordPress site to Zapier. Every time I try, I get a ‘403 forbidden’ error. I’ve been messing around with my Nginx config file to fix it, but no luck so far.

Here’s what I’ve added to my Nginx conf:

location = /xmlrpc.php {
    include zapier_allowlist;
    deny all;
    access_log off;
    log_not_found off;
}

And in my zapier_allowlist file, I’ve put in some Zapier IP ranges:

allow 18.30.0.0/16;
allow 36.180.0.0/14;
allow 36.240.0.0/13;
allow 37.160.0.0/16;
allow 37.176.0.0/15;
allow 54.20.0.0/14;
allow 54.24.0.0/15;
allow 56.0.0.0/13;

I’m pretty stuck at this point. Any ideas on how to get this working? Thanks in advance for any help!

I encountered a similar issue when integrating WordPress with Zapier. Have you considered checking your WordPress permalink settings? Sometimes, switching to a plain permalink structure temporarily can help isolate the problem. Also, ensure your WordPress installation is up to date, including all plugins and themes. Outdated components can sometimes cause unexpected behavior with external integrations.

Another thing to look into is your server’s mod_security rules if you’re using Apache. These can sometimes interfere with XML-RPC requests. If you’re using a managed hosting service, you might need to contact their support to whitelist Zapier’s IP ranges on their end.

Lastly, try temporarily disabling your WordPress security plugins to see if they’re causing the issue. Remember to re-enable them once you’ve isolated the problem.

I’ve dealt with this ‘403 forbidden’ headache before, and it can be a real pain. One thing that worked for me was tweaking the WordPress Authentication Unique Keys and Salts. These are in your wp-config.php file. Try regenerating them from the WordPress.org secret-key service.

Also, double-check your .htaccess file. Sometimes it can get wonky and cause these issues. Rename it temporarily to see if that resolves the problem. If it does, you can generate a fresh one through WordPress.

Lastly, don’t forget about SSL. If your site is using HTTPS, make sure Zapier is trying to connect via HTTPS as well. Mismatched protocols can cause these kinds of errors.

Hope this helps. Let us know if you get it sorted!

hey alice, i had the same issue! try adding these lines to ur wp-config.php:

define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);

it’ll give u more info in the error logs. also, double-check ur zapier IP ranges - they might’ve changed. Good luck!
