What’s new and updated in Buildkite

Upcoming change to the Buildkite API

Posted July 31, 2023 by James

To enhance the overall reliability and scalability, we are implementing changes to how Buildkite handles API GET requests that include a body in the payload starting September 18th.

As a result of these changes, any GET request to that includes a body will receive a 403 status (Forbidden) as a response.

This may impact legacy clients, particularly older versions of Buildkite's Terraform provider (< 0.15). To ensure compatibility, we recommend upgrading to the latest version of our Terraform provider.

During the week commencing August 28th, Buildkite will intermittently enable this change for short periods as a low-impact method of uncovering issues.

We value our customers and their experience with Buildkite, so we will directly communicate with any customers continuing to submit API GET requests with a body.

Thank you for your understanding and cooperation as we continue to improve our platform.

Update: We originally advised this change would occur on August 14th, we have delayed this change to September 18th.
