MessagePack format guide

Sample MessagePack files

Small binary MessagePack files with the same users, projects and tasks as the JSON files. Use them to test MessagePack decoders and binary response handling, then compare the result with the matching JSON file. Pick a whole collection (3 users, 2 projects or 3 tasks) or a single record. The 11 files range from 104 B to 961 B.

No account or API key is needed. A published v1 file never changes, its SHA-256 is listed in the manifest, and the data is CC0, so you can also commit a copy to your own repository.
