Simpro Rate Limits

Simpro enforces an API rate limit of 10 calls per second, in effect since 9 August 2022. The limit is scoped to the whole Simpro domain (build), not to a single user or company - so on a multi-company build, all companies and integrations share the same budget. Requests over the limit receive an HTTP 429 response and should be retried with backoff. Simpro notes that most integrations never reach the limit; only the highest-volume callers need to manage it.

Simpro Rate Limits is the machine-readable rate-limit profile for Simpro on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring requests.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Field Service Management, Trades, Job Management, Rate Limiting, and Quotas.

Limits

Overall API Rate build
requests
10 per second
Scoped to the whole Simpro domain/build; shared across companies and integrations on that build. Effective 9 August 2022.
Burst Handling build
requests
not published
No separate burst allowance is documented; sustained rate above 10/sec returns HTTP 429.

Policies

Backoff Strategy
On HTTP 429, back off and retry with exponential backoff and jitter.
Domain-Scoped Budget
The limit applies to the entire build, so coordinate multiple integrations and companies sharing one build to avoid collisions.
Request Minimization
Use pagination (pageSize / page), search filters, and the columns parameter to fetch only needed data and reduce call volume.
