How to allow incoming WooCommerce Zapier requests

[tnvski]

Hi there, I am facing with “authentication failed: “Service Unavailable” response received. HTTP status: “503” on https://…” so I need to configure Cloudflare to allow incoming WooCommerce Zapier requests.

I need to allow these two URLs

/wc-zapier-auth/v1/authenticate
/wp-json/wc-zapier/v1/*

How should I do it? Thanks

I am not sure about Zappier, but could you double-check in their Docs for some of their IPs, just in case?

I’d suggest you to whitelist your origin host / server / hosting IP address by navigating to the Security → Tools → IP Access Rules with the action “allow” for your Website and try again.

Maybe the same has to be done for their IP (range)?

Despite their long list AWS IP ranges available here:

Furthermore, maybe some of my earler post below could help you a bit for troubleshooting:

Cloudflare with Zapier and Wordpress

Have you blocked access to your XML-RPC due to security reasons? Do you have some security plugin installed like Wordfence Security? Using Cloudflare Firewall? Are you blocking your REST API access? Or allowing only to autenticated user with granted rights /password to access it? Have you tried contacting Zapier about your issue? You can contact them here: Zapier Support.
