Create a Feature Flag Logic
Generate code for a feature flag to safely toggle between the old and new API versions during rollout.
Generate the logic for a feature flag in [language] to toggle between the old API version and the new one. This will allow for a gradual rollout. The function should take a context object to decide which API version to call.
Develop a Rollback Plan
Outline a technical plan for quickly reverting the API integration if critical issues arise post-deployment.
Outline a technical rollback plan in case the new API integration causes critical issues in production. The plan should include steps for reverting code, managing feature flags, and communicating the rollback. Our deployment process is: [describe process].
