Zapier is a great tool for creating automated tasks on your WordPress site or triggering actions when you create new posts or pages.
We’ve tested Zapier to create new posts in WordPress while the WP Ghost plugin is active and set in Safe Mode or Ghost Mode.

We noticed that Zapier needs access to the xml-rpc.php file to work properly.
- Go to WP Ghost > Change Paths > API Security section.
- Switch on the Disable XML-RPC access option to disable access to xml-rpc.php file.
- Go to WP Ghost > Firewall > Whitelist section.
- Add the Zapier User Agent into whitelist to allow API calls from Zapier.
- Click the Save button to apply the changes.
Test the Zapier API after whitelisting the IP addresses for Zapier, as some IP addresses may change over time. Check the Amazon official IP list in JSON format and extract the most recent IP addresses if you still have an error. https://ip-ranges.amazonaws.com/ip-ranges.json
