Manage prospects, accounts, opportunities, sequences, tasks and webhooks in Outreach through its JSON:API REST API.
Outreach ships in the w6w first-party pack. It declares 30 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.outreachOutreach is a sales engagement platform: prospects and accounts are worked through multi-step sequences of emails, calls and tasks, and the results flow into opportunities. This app gives a workflow the core of that surface over Outreach’s JSON:API REST API (v2).
It covers the full create/read/update/delete lifecycle for prospects and accounts, reading and creating opportunities, listing sequences, and the sequence-state lifecycle that actually starts and stops outreach to a prospect: enrolling a prospect in a sequence, then pausing, resuming or finishing them. It also lists and creates tasks, marks them complete, creates prospect notes, lists mailings and users, and manages webhooks so a workflow can react to Outreach events instead of polling.
Every list action speaks Outreach’s own filter, sort, include, sparse-fieldset and cursor-pagination grammar, and returns the JSON:API document as Outreach sent it plus a ready-to-use nextCursor. Webhook signing secrets and cleanup tokens are removed from every response, and the health checks read Outreach’s documented rate-limit headers.
Three routes to the same 30 actions. The Workflow tab is generated from Outreach's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
account-create Create an account (company). Retrying a create can produce a duplicate.
account-list List accounts (companies) with Outreach filters, sorting and cursor pagination. Unnamed accounts are not returned by default.
mailing-list List mailings (emails sent or scheduled through Outreach) with their delivery, open, click and reply state.
opportunity-create Create an opportunity, optionally tied to an account, owner and stage.
opportunity-list List opportunities with Outreach filters, sorting and cursor pagination.
prospect-create Create a prospect. Outreach has no idempotency key, so retrying a create can produce a duplicate; look the prospect up first when that matters.
prospect-list List prospects with Outreach filters, sorting and cursor pagination. Since 1 Oct 2026 the `contactHistogram` attribute is no longer in the default payload; request it with Fields.
sequence-get Fetch one sequence by ID, including its enabled/locked state and engagement counts.
sequence-list List sequences. Use this to find the sequence ID that Add Prospect to Sequence needs.
sequence-state-create Enroll a prospect in a sequence by creating a sequence state. The prospect, the sequence and the mailbox the emails go out from are all required; the sequence's automation starts immediately.
sequence-state-finish Finishes a sequence state, removing the prospect from the sequence, by sequence state ID.
sequence-state-list List sequence states — one per prospect enrolled in a sequence. Filter with `{"prospect": {"id": "1"}}` or `{"sequence": {"id": "2"}}` to see who is in what, and read `state` (active, pending, finished, paused, disabled, failed, bounced, opted_out).
task-list List tasks. For a rep's open work filter `{"state": "incomplete", "owner": {"id": "1"}}` and include `prospect`.
task-mark-complete Mark a task complete, optionally attaching a note to its prospect.
webhook-create Subscribe a URL to Outreach events. Resource and action default to `*` (everything). If you set a secret, Outreach signs each delivery with an HMAC in `Outreach-Webhook-Signature`. The secret and the cleanup token are not returned by this action.
webhook-list List webhooks. Each webhook's signing `secret` and `cleanupToken` are removed from the result.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Outreach's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Outreach, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Outreach. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.outreach#account-get",
"input": {
"id": "<id>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Outreach connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Outreach's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Outreach itself is MIT, and the runtime that executes it is source-available (FSL).
Outreach declares its own checks, so its health is a property of the app rather than something the host guesses at.
