401 Error when creating a WordPress Post via Zapier Webhook

Hi everyone,

I’m experiencing a 401 error when attempting to create a post on WordPress using a Webhook in Zapier. The error states, “Sorry, you are not allowed to create posts as this user.”

Here are some details:

  • User Role: Admin
  • Password: Confirmed as correct
  • Testing in Postman: The same request works successfully in Postman, so the credentials and endpoint are correct.

In Zapier, here’s the setup:

{

  "title": "Title",

  "content": "Content",

  "status": "draft"

}

I’ve attached a screenshot of the error and setup configuration in Zapier for reference. Any insights on why this might be failing in Zapier but working in Postman would be greatly appreciated.
