Rate Limits

Parcel applies a rate limit to every request authenticated with a workspace API key.

The limit

100 requests per minute, per API key.

The limit is counted per individual key, not per workspace. Each key you create gets its own budget, so separate integrations never compete for the same allowance. Requests made through the Parcel web app (signed-in sessions) are not subject to this limit.

When you exceed it

A request over the limit receives an HTTP 429 Too Many Requests response with a Retry-After header telling you how many seconds to wait before retrying:

429 response

HTTP/1.1 429 Too Many Requests
Retry-After: 60

Build your integration to honor Retry-After and retry idempotent requests with exponential backoff. Spreading requests evenly over time, rather than sending them in bursts, keeps you comfortably under the limit.

Need a higher limit?

If your integration needs more throughput, reach out to the Parcel team. We’re happy to raise the limit for your workspace.
