WARNING: Travis-ci support is incomplete. This only documents existing behavior.
HTTP requests to the /event/travis endpoint must be validated that they
originated from Travis-ci. Github and Travis. Travis-ci post-build notifications
are sent with an AUTHORIZATION header containing the pattern
#{username}/#{repository}#{TRAVIS_AUTH_TOKEN}. In order to receive events from
Travis-ci, the TRAVIS_AUTH_TOKEN environment variable must be set to match the
Travis token of the Github user configured to interact with the Travis-ci API.
For more information, see the Travis post build notification documentation.
