I’m working on setting up webhook integration between WordPress and Zapier using Cloud9 IDE for testing purposes. My plan is to get this working first before deploying to a production WordPress host.
The WordPress installation on Cloud9 runs without any problems, but I keep running into issues when trying to link my Zapier account with the WordPress site. Every time I attempt the connection, I receive this error message:
“We hit an error adding your new account authorization failed: ResponseError()”
I suspect this might be related to CORS (Cross-Origin Resource Sharing) restrictions, but I’m not sure how to troubleshoot the authentication process from Zapier’s end.
Has anyone here managed to successfully integrate Zapier with a WordPress site running on Cloud9? If you have, did you need to configure any particular CORS settings or make other adjustments to get the connection working?
had the same cloud9/zapier auth nightmare. it’s usually the redirect uri - zapier wants a clean url but cloud9 gives you those ugly workspace urls. use ngrok to tunnel your cloud9 instance, then connect zapier to that url instead. fixed it for me when everything else failed.
I hit the same authorization failure with Zapier and WordPress in dev environments. Turns out it wasn’t CORS - the auth flow was getting confused by the development URL structure. Cloud9 environments use dynamic URLs with port numbers and complex subdomains, which mess with OAuth callbacks. Here’s what worked for me: create a simple test webhook endpoint first using basic PHP that just logs incoming requests, then build up the auth layer step by step. Also check if your Cloud9 environment is accessible from external services - sometimes security settings block incoming connections from third-party services like Zapier. Try testing with a simple webhook receiver first to see if it’s an auth problem or broader connectivity issues.
ResponseError() usually means timeout issues, not authentication problems. Cloud9 has spotty connectivity that kills webhook handshakes. I’ve dealt with this before - the environment goes to sleep or stops responding during OAuth. Keep your Cloud9 workspace awake during connection attempts and make sure WordPress accepts external connections. Check your Cloud9 security group settings too - ports 80/443 need to be open. Also verify WordPress has the right plugins enabled for webhooks. Sometimes it fails because WordPress can’t handle Zapier’s initial handshake properly.
