Learn more about the process: https://handbook.gitlab.com/handbook/product/how-to-engage/#customer-feature-requests. The section "Release notes" can be used as a summary of the feature and is also required if you want to have your release post blog MR auto generated using the release post item generator: https://about.gitlab.com/handbook/marketing/blog/release-posts/#release-post-item-generator. The remaining sections are the backbone for every feature in GitLab. The goal of this template is brevity for quick/smaller iterations. For a more thorough list of considerations for larger features or feature sets, you can leverage the detailed [feature proposal](https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md). --> ### Problem to solve The customer needs to configure a project webhook in their GitLab self-managed instance to an external URL on the internet. In order to access the internet, they require proxy authentication. They don't want to activate the proxy globally for security reasons and want to limit it to the specific URL. ### Proposal When creating a webhook, create a provision for configuring proxy authentication using username and password.
