Travis CI APIs

API V3 #

The Travis CI API V3 was released on 6th April 2017. It is a discoverable and self-documenting RESTful API, and includes all the hypermedia features expected from a modern API.

Our API can be used to automate many of your Travis CI build processes:

  • get build info
  • get organization info
  • get nested resources
  • restart builds or jobs
  • cancel builds or jobs
  • trigger debug builds
  • deal with pagination
  • edit environment variables
  • validate the .travis.yml file

We’ve created an API Explorer that closely integrates with V3, updating automatically when new endpoints are added, and includes a useful tool for exploring endpoints.

API V2.1 #

We’ve released an update to the Travis CI API V2, which is API V2.1. This update essentially makes HTTP status codes more consistent between and

If you are building both Open Source and Private projects on, please use API V2.1.

For users of Travis CI using the deprecated platform for Open Source projects at, built at, there is no change in API.

API V2.1 is identical to API V2 except for the following breaking changes:

  • For public repositories, unauthenticated requests receive an HTTP 200 or an HTTP 404 error in some cases like for repo caches or settings.
  • For private repositories, unauthenticated requests receive an HTTP 401 or 404 error.
  • For private repositories, authenticated requests by users that do not have permission to view the repository receive an HTTP 400 error or HTTP 200 for empty responses.

Previous behavior for V2 is that these requests receive an 401 error.

A similar pattern of HTTP response codes applies to other endpoints such us /builds, /branches, /jobs and /requests.

To use API V2.1 set the Accept header of your API request to application/vnd.travis-ci.2.1+json.

API V2 #

We’re not yet ready to deprecate API V2. We use V2 with our web frontend application and have spent the last 6 months switching gradually from V2 to V3. We’ll complete this transition in the coming months, but plan to continue supporting V2 until the end of 2017. We’ll naturally give developers ample notice before switching V2 off, and provide detailed instructions for making the transition to V3.

Ruby Library #

The Ruby Library uses the API V2.
