### Problem to solve <!-- What problem do we solve? --> Broken off of [Make managing feature flag environments and strategies easier ](https://gitlab.com/gitlab-org/gitlab/issues/35555) - this represents the first iteration of provided the users with a public API that can create feature flag strategies and apply them to environments. ### Intended users <!-- Who will use this feature? If known, include any of the following: types of users (e.g. Developer), personas, or specific company roles (e.g. Release Manager). It's okay to write "Unknown" and fill this field in later. * [Rachel (Release Manager)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#rachel-release-manager) * [Parker (Product Manager)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#parker-product-manager) * [Delaney (Development Team Lead)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#delaney-development-team-lead) * [Sasha (Software Developer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sasha-software-developer) * [Presley (Product Designer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#presley-product-designer) * [Devon (DevOps Engineer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#devon-devops-engineer) * [Sidney (Systems Administrator)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sidney-systems-administrator) * [Sam (Security Analyst)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sam-security-analyst) * [Dana (Data Analyst)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#dana-data-analyst) Personas are described at https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/ --> * Developers who create feature flags * QA engineers enabling/disabling flags * Release managers who want to control which features are released and to which customer base * Support engineers that wish to release features to beta customers or test version to fix bugs for specific customers ### Further details <!-- Include use cases, benefits, and/or goals (contributes to our vision?) --> ### Proposal <!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey --> Breakdown is as follows: * [ ] 1 for tables * [ ] 1 for CRUD operations * [ ] 1 for API CRUD operations * [ ] 1 for Unleash API * [ ] 1 documentation APIs needed: * Create strategy * Edit Strategy * Delete Strategy Similar to https://github.com/Unleash/unleash/blob/master/docs/api/admin/strategies-api.md * GET: http://unleash.host.com/api/admin/strategies * POST: http://unleash.host.com/api/admin/strategies * PUT: http://unleash.host.com/api/admin/strategies/:name This API will be used as public API and also for FE use This Public API will be a beta and will only be available for gitlab.com for a trial period. Follow up issue https://gitlab.com/gitlab-org/gitlab/issues/205487 created to enable this for Self-Managed at the end of the trial period. ### Permissions and Security <!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)?--> ### Documentation <!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html Add all known Documentation Requirements here, per https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html#documentation-requirements If this feature requires changing permissions, this document https://docs.gitlab.com/ee/user/permissions.html must be updated accordingly. --> ### Availability & Testing <!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier. What risks does this change pose to our availability? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing? Please list the test areas (unit, integration and end-to-end) that needs to be added or updated to ensure that this feature will work as intended. Please use the list below as guidance. * Unit test changes * Integration test changes * End-to-end test change See the test engineering planning process and reach out to your counterpart Software Engineer in Test for assistance: https://about.gitlab.com/handbook/engineering/quality/test-engineering/#test-planning --> ### What does success look like, and how can we measure that? <!-- Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this. --> ### What is the type of buyer? <!-- Which leads to: in which enterprise tier should this feature go?
