For a person who joined, removal takes effect at once: their sessions in the workspace end, the API keys they created in it are revoked, and they no longer appear in the workspace. A cancelled invitation's link stops working. To bring someone back, invite them again. Only owners and admins can remove members. Only an owner can remove an owner, and the workspace's last owner cannot be removed. > [!WARNING] > > API keys cannot call this endpoint: it answers `403 FORBIDDEN_ACTION` ("API keys cannot > access this endpoint."). Remove members in Heliyos under Settings, Team. Removal cannot be > undone. > [!NOTE] > > In the Heliyos MCP server: [`heliyos_team_members_remove`](https://docs.heliyos.ai/mcp/tools/team#heliyos-team-members-remove). ## OpenAPI ````yaml /api-reference/openapi.json delete /v1/auth/team-memberships/{id} openapi: 3.0.3 info: title: Heliyos API version: 1.0.0 description: >- The REST API for Heliyos, the AI operating system for revenue. Every request is scoped to the workspace that owns the API key. Responses are JSON in a `{ meta, data }` envelope; errors use `{ message, error: { code, message, details } }`. contact: name: Heliyos support email: soham@heliyos.ai url: https://www.heliyos.ai servers: - url: https://api-prod.heliyos.ai description: Production security: - bearerAuth: [] tags: - name: Workspace description: >- The workspace your API key belongs to, and the log of credits it has used. Every other call in this API is scoped to this workspace. - name: Schemas description: >- Objects are your record types: companies, people, deal pipelines and any custom objects you add. Each object has fields, and a field's type decides what its records can hold. - name: Records description: >- Records are the rows of an object (base schema): companies, people, deals and custom objects. A record holds field values keyed by the object's field keys and links to other records. - name: Timeline description: >- The AI-written timeline of a company, person or deal: summary entries Heliyos writes on a schedule. For the exact change history see Activities, and for emails and meetings see Interactions. - name: Activities description: >- The change history of records and tasks: who created, changed or deleted what, and when. People, workers and the system each appear as the actor on the changes they make. - name: Interactions description: >- Email threads and meetings synced from connected mailboxes and calendars, linked to the people and companies they involve. - name: Notes description: >- Free-text notes, optionally linked to records, tasks and interactions. Notes show up on the timeline of every record they are linked to, and workers read them as customer memory. - name: Tasks description: >- Work items for people and workers, optionally linked to records. A task can be assigned to people, to workers, or both, and workers can be started on it directly. - name: Workers and runs description: >- Workers are the AI teammates of your workspace (the API calls them agents). Define what each one does and what starts it, ask Heliyos to do work, and follow every run, its steps and the reviews it waits on. - name: Reviews description: >- Reviews keep the team in control of consequential work. When a worker wants to send an email, change a deal, book a meeting, act in a connected app or needs a person's answer, the action waits as a review until someone approves or rejects it. - name: Scouts description: >- Scouts watch companies and the web for events such as funding rounds, product launches, leadership changes or press coverage, and record each finding as a signal. A workspace Scout defines what to look for; company Scouts are its copies running on individual companies. - name: Signals description: >- Signals are what Scouts find: one event, such as a funding round or a new executive, with a summary, its sources and the company it is about. New signals are unread until you mark them read. - name: Watchlist description: >- The watchlist is the set of companies your workers monitor. Each watched company uses one Watcher from your plan: the workers keep it enriched, pull in its emails and meetings, and run Scouts on it. - name: Knowledge base description: >- What your workers know about the business: the business context, four fixed texts (products, pain points, value proposition, qualification criteria) and any custom entries your team adds. Workers read it on their next run. Files your workers read live under Files, with kind `knowledge_base`. - name: Files description: >- Knowledge base files that workers read, and files attached to records, tasks and other resources. The API calls them attachments. Uploading takes three calls: get an upload URL, send the bytes to it, then create the file. - name: Labels description: >- Label groups that sort your email threads, for example Intent or Pricing questions. Heliyos files each classified thread under a group, and each group holds the more specific labels it brings together. The API calls them classification labels. - name: Team description: >- The people in your workspace and their roles: joined members and pending invitations. Inviting someone sends them an email. - name: Notification settings description: >- Which workspace events send notification emails, how often, and to whom. There is one settings document per workspace, shared by everyone in it. paths: /v1/auth/team-memberships/{id}: delete: tags: - Team summary: Remove a team member description: >- Removes a person from the workspace, or cancels a pending invitation, by membership id.
