Outreach

Outreach is a sales execution and revenue platform for go-to-market teams, unifying email, calling, social and meetings into sequenced outbound motions with AI agents layered on top. Its public developer surface is a JSON API 1.0 REST API at api.outreach.io/api/v2 covering accounts, prospects, opportunities, sequences, sequence states, mailings, calls, tasks, teams, users, imports and webhooks across 51 tagged resources and 253 operations, authorized by OAuth 2.0 with a scope-per-resource permission model and a separate server-to-server JWT token for unattended integrations. Outreach also runs a remote Model Context Protocol server at api.outreach.io/mcp with 41 tools, authorized by OAuth 2.1 with PKCE and Dynamic Client Registration, plus a client extensibility SDK for embedding web widgets inside the Outreach app, an event-driven webhook surface with HMAC-signed deliveries, and Outreach Data Sharing over Snowflake and Delta Sharing.

Outreach publishes 52 APIs on the APIs.io network, including Webhooks, Account API, Account Note API, and 49 more. Tagged areas include Sales, Sales Engagement, Sequences, CRM, and Email.

Outreach’s developer surface includes authentication, changelog, documentation, API reference, getting-started guide, support, pricing, and 31 more developer resources.

scored 2026-09-14 · rubric v0.22.0
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/outreach: open an issue to ask a question, or submit a pull request to add artifacts.
