Buffer’s legacy REST API retirement, act now
As a branding content curator I recommend this update to every developer and brand using Buffer. Buffer will retire its legacy REST API on February 1, 2027, making migration essential.
Their GraphQL Public API is built for modern workflows, and it powers Buffer’s own apps. The company plans two brownouts in November and December 2026, before the final sunset. Key differences include cursor based pagination, per post scheduling, and one channel per request.
If you maintain integrations start the migration now, consult the detailed REST migration guide for endpoint mappings. Buffer offers support via Discord and developer support email, and they welcome feedback on missing capabilities. Read the original post for timelines, migration notes, and practical next steps, before the brownouts begin.
This shift reduces maintenance overhead, streamlines developer experience, and aligns Buffer with modern API practices. Curators and product teams should read this post now, to plan migrations and avoid service disruption.
The post is a clear guide, it balances technical detail with practical migration steps. I strongly recommend teams review the migration checklist, update client calls, and test against GraphQL endpoints.
