Example Output
Deprecation Announcement
We are deprecating the /v1/reports/export endpoint on June 30 and will remove it on September 30. The replacement is /v2/exports, which adds async job status, stronger filters, and more reliable pagination. Existing integrations should migrate before August 31 to avoid production risk.
Breaking Change Summary
| Old | New | Action |
| --- | --- | --- |
| synchronous export response | async job creation + poll | update client flow |
FAQ
**Will existing API keys still work?** Yes, authentication stays the same.
Tips for Best Results
- 💡List the exact endpoints, fields, and dates so the AI can produce concrete migration guidance.
- 💡Include one before-and-after code example if you want a more useful guide.
- 💡Ask for separate enterprise-customer wording if major accounts need a softer rollout message.
- 💡Do not bury removal dates, developers need them high in the announcement.
