As of February 1st, 2019, every repository integrated with Travis CI via a GitHub service hook has been migrated to use GitHub webhooks.
If you have repositories connected to
travis-ci.com, we recommend activating GitHub Apps by heading to your account repositories page and use the “Activate & Migrate” or "Manage repositories on GitHub" option to start using GitHub Apps.
You can find more information on why GitHub Apps is the preferred integration type on the GitHub developer documentation.
If you have any questions, please reach out to us on the Travis CI Community Forum.
