The Developer API has no usage limits: no monthly quotas or total-call caps. What you build against is a rate limit:
- 10 requests per second, per workspace. Every
/v1 and /v2 endpoint counts against it, and all of a workspace’s credentials (PATs and OAuth apps) share the same budget.
This is an interim limit while we finalize per-endpoint rate limits. We’ll update this page when they change.
Going over the limit
Requests beyond the limit are rejected with 429 Too Many Requests. Back off briefly and retry. Exponential backoff with a little jitter is plenty.
Pushing a large batch, like seeding contacts or email versions from a big table? Pace the run instead of firing everything at once. Most integration tools have a rate-limit setting, and a few calls that can be made once per run (like checking that a list exists) don’t need to be repeated for every row.
