All published endpoints are mounted under `/api`. Responses use a standard envelope: `{ "success": true, ... }` on success and `{ "success": false, "error": "..." }` on failure. Product API modules are being launched module by module. This spec currently exposes only contracted public modules. Authenticate public API requests with an API key in the `Authorization` header: `Authorization: Bearer YOUR_API_KEY`. servers: - url: https://api.teamfollowup.ai description: Production API origin. Public API paths are under /api. - url: https://devapi.teamfollowup.ai description: Development API origin. Public API paths are under /api. security: [] tags: - name: Agents description: Manage voice agents, campaigns, workflows, and outcomes. - name: Analytics description: >- Minimal, non-billing performance summary: volume, conversion, and pickup metrics. - name: Calls description: Review calls, test runs, and execution history. - name: Campaign Workflows description: >- What runs after a call lands: for each outcome (booked, opted out, asked for a callback…), an ordered chain of actions — tag the contact, move a pipeline stage, send an SMS, book an appointment. Stored as a graph: `nodes` are the actions, `edges` say what follows what, and `dispositionEntries` maps each outcome to the node its chain starts at. **Pick the narrowest endpoint that does the job.** | To | Call | | | --- | --- | --- | | See what fires per outcome | `GET .../workflow/digest` | Reads as plain text, no graph walking | | Add steps to an outcome | `POST .../outcomes/{outcome}/nodes` | Server derives node ids, edge ids, handles, layout | | Change a message, tag or setting | `PATCH .../workflow` | Merges; carries no graph, so it cannot damage one | | Remove one step | `DELETE .../nodes/{nodeId}` | Also re-links the chain around it | | Author or replace the whole graph | `PUT .../workflow` | Replaces everything you send | `PUT` is the only one that can re-wire, position nodes, build an `if`, save an unconfigured draft, or copy a whole workflow — and the only one that can overwrite a change someone else made after you read it. Use it when you are genuinely authoring the graph, and send `expectedVersion` when you do. For everything else the narrower endpoints are both easier and safer. - name: Contacts description: Contact list, filters, contact call history, and do-not-call actions. - name: GHL description: CRM variables and contact helpers used by agent and campaign setup flows. - name: Phone Numbers description: >- Caller ID pool, number search, assignment, movement, and release endpoints. - name: Power Dialer description: >- Power Dialer queue, lead cadence, callback, parked lead, and campaign schedule endpoints. - name: Projects description: >- Project management endpoints: list, update, disconnect, configure project campaigns, and validate setup. - name: Skills and Tools description: Manage reusable agent behaviors and in-call tool descriptions. - name: Voices description: Voice catalogue endpoints for choosing the voice used by an agent. paths: /api/power-dialer/pipeline/callbacks: get: tags: - Power Dialer summary: List callback leads description: >- List callback leads waiting for their promised callback time.
