I've created a pipeline trigger in Gitlab as the documentation said, but when I open it I get a "error": "404 Not Found".
Webhook URL: https://gitlab.com/api/v4/projects/xxxx/ref/xxxx/trigger/pipeline?token=xxxx
xxxx is being replaced by the values I have. Tried different things, setting the project to public. Enabling/disabling Limit CI_JOB_TOKEN acces.
I'm a bit lost right now.
As examples show you need to use http POST method
curl -X POST $WEBHOOK_URL
If you are pasting the URL directly to your browser it will use http GET and result in 404 error.
The feature that you are referencing in the question might not be working due to a GitLab bug that was introduced in 12.0.0. Please see the issue here: https://gitlab.com/gitlab-org/gitlab/-/issues/30486
