Outreach Rate Limits

Published rate limits for the Outreach REST API. Outreach rate-limits primarily on a per-user basis at 10,000 requests per hour, with tighter org-level limits on Kaia recordings/transcripts, a token-minting throttle on the OAuth token endpoint, and a separate annual API-call entitlement attached to each commercial plan (250,000 to 1,000,000 calls depending on tier — see plans/outreach-plans-pricing.yml).

Outreach Rate Limits is the rate-limit profile for Outreach on the APIs.io network — every limit transcribed verbatim from the provider’s own documentation on 2026-08-13.

It captures 4 rate-limit definitions, including REST API default — with a limit of 10,000 requests per hour; Kaia recordings and transcripts (burst) — 3 API calls per second; Kaia recordings and transcripts (daily) — 6,000 API calls per day.

Limit state is signalled in the X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, and Retry-After response headers, and an exhausted limit returns HTTP 429.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled and maintenance.

Tagged areas include Sales, Sales Engagement, Sequences, CRM, and Email.

Policies

Backoff strategy
Honor X-RateLimit-Reset / Retry-After before retrying. Outreach reserves the right to adjust API rate limits at any time to safeguard platform performance.
Endpoint-specific rules
Some endpoints (bulk/batch API, Kaia) apply special rules beyond the per-user default.
