The steps below follow Outreach's own docs. 1. Create a Outreach account. API access starts on the Amplify Core plan. 2. Create an Outreach app in the Developer Portal, configure API access (redirect URIs, scopes). Dev credentials work immediately for up to 10 people in the owning org; production credentials need publishing (public Marketplace apps need a demo and 5 beta customers). Access tokens expire in 7,200 s with refresh tokens. Alternative S2S token (RS256 JWT from your app key + install ID) covers only a limited endpoint set. 3. Send it with every request: header: Authorization: Bearer ; Content-Type must be application/vnd.api+json. 4. Make a first call: Get a Collection of Account Notes. Keep the key in an environment variable, never in the command. ``` curl -X GET "https://api.outreach.io/api/v2/accountNotes" \ -H "Authorization: Bearer $OUTREACH_ACCESS_TOKEN" ``` ## Where the docs live What Where Documentation [developers.outreach.io/api](https://developers.outreach.io/api/) API reference [developers.outreach.io/api/reference/overview](https://developers.outreach.io/api/reference/overview/) OpenAPI spec [developers.outreach.io/page-data/shared/oas-api/reference.yaml.json](https://developers.outreach.io/page-data/shared/oas-api/reference.yaml.json) llms.txt [developers.outreach.io/llms.txt](https://developers.outreach.io/llms.txt) Changelog [developers.outreach.io/api/release-notes.md](https://developers.outreach.io/api/release-notes.md) Base URL `https://api.outreach.io/api/v2` SDKs Client-extension JavaScript SDK (in-app extensions, not a REST client) ## Strengths and limits ### Where it fits - Integrating with an enterprise customer's existing Outreach org (sequences, prospects, accounts, opportunities, tasks, calls, mailings) - Event-driven sync via webhooks on mailing delivered/opened/replied/bounced and sequenceState changes - Large imports: bulk actions up to 100,000 items per request, CSV import and bulk upsert - Agent access with user-level RBAC via the hosted MCP (OAuth 2.1 + DCR) ### Where it falls short - Self-serve or startup cold email: no public price, seats only via sales - Simple API-key scripts: every call needs an OAuth app (or S2S JWT for a limited endpoint set) - Deep pagination of huge collections: max offset 10,000, page limit 1,000 ### Worth knowing - No public pricing at all: every Amplify tier is 'Request pricing'. - Requests must send Content-Type application/vnd.api+json or get 415 (JSON:API 1.0). - Rate limit is per USER (10,000/h), so a single integration user is a bottleneck; Kaia transcript endpoints are 3/s and 6,000/day per org. - Max pagination offset is 10,000 and page\[limit\] max 1,000; page across ID ranges or tighter filters instead. - Development OAuth credentials are meant for up to 10 users of the owning org and grants can be expired/revoked; customer installs need a published app, and public Marketplace listing needs a demo plus 5 beta customers. 6 moreShow fewer - S2S tokens carry no user identity: reads work, but some writes need an extra authorizer user id or fail entirely. - OAuth client secrets are shown once; regenerate if lost. - From 1 Oct 2026 prospect responses drop contactHistogram by default (deprecation notice). - Bulk upsert batch results are deleted after 30 days. - Webhooks are not retried on any HTTP error status (500 and 429 count as delivered); only network failures get 3 retries 1 s apart, with a 5 s timeout. - Non-customers cannot self-serve API access: [outreach.ai/platform/api](https://www.outreach.ai/platform/api) routes to a manually reviewed 'Outreach API Access Request' form; the Developer Portal 'My apps' requires an existing Outreach user login. ## Who should use it Use Outreach for Integrating with an enterprise customer's existing Outreach org (sequences, prospects, accounts, opportunities, tasks, calls, mailings) Look elsewhere for Self-serve or startup cold email: no public price, seats only via sales ## If Outreach is not the answer Other Email sending tools in this directory, each with its own review.

It is sent as: header: Authorization: Bearer ; Content-Type must be application/vnd.api+json. - **Design around the rate limit**Per user: 10,000 requests per hour, with X-RateLimit-Limit/Remaining/Reset (alias Retry-After) headers and 429 on excess. - **Know the catch before you scale**No public pricing at all: every Amplify tier is 'Request pricing'. ## Want us to build it for you?
