Act! CRM · Rate Limits

Act Rate Limits

Act! states that Act! Premium Cloud API requests are rate limited and names the three response headers a client should read. It does not publish a number: no request-per-minute figure, no per-plan quota, no burst allowance, and no status code for exhaustion. The runtime signal is therefore the only way to discover the limit — read X-RateLimit-Limit on the first response.

Act Rate Limits is the rate-limit profile for Act! CRM on the APIs.io network.

The provider publishes no rate limits that could be read; the profile records that absence rather than inventing a ceiling.

Limit state is signalled in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers.

The profile also includes response codes documented for throttled and note.

Tagged areas include CRM, Marketing Automation, Contact Management, Sales, and Opportunity Management.
