CSRF validation failed in Drupal

I'm using a webservice in Drupal 7. If I try to use Poster I get 'CSRF validation failed'. Before, I was connected with an administrator account.

I use the Firefox add-in Poster.

How can I fix this problem?

Solution

  • You need to pass along the CSRF token in the header of the service request.

    To retrieve the token, navigate to:

    http://www.example.com/?q=services/session/token

    Copy the token to your clipboard.

    Then in FireFox poster, using the "Headers" tab, add this name and value:

    Now when you make requests, the token will be passed along correctly with FireFox Poster.

    Here's a detailed blog post outlining this topic:
