# List collaborators

`GET /api/apps/{app_id}/users/collaborators`

## Request

- Base URL: `https://app.base44.com`
- URL: `https://app.base44.com/api/apps/{app_id}/users/collaborators`
- Auth: HTTP bearer

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Returns the people who can edit the app in Base44, owner first, then everyone else by email. Invite more with [Invite app users](/api-reference/invite-app-users) and `collaborator_role` set to `editor`. The list isn't paginated.

Guests in the app's workspace can't list collaborators. Base44 staff who can edit the app are left out, unless they own it or are a guest in its workspace.

This is limited to 60 requests per minute per app for each workspace's personal API keys, so every key in a workspace shares one allowance. List collaborators and Remove collaborator share it. Some workspaces have a different limit.

<Note>This endpoint accepts a personal API key belonging to a user with editor access to the app, including a read-only key. Workspace API keys are not accepted.</Note>

## Path parameters

- `app_id` string, required: ID of the app whose collaborators to list.

## Response `200`

The app's collaborators, owner first.

- CollaboratorResponse[]: The app's collaborators.
  - `id` string, required: ID of the collaborator. Pass it to [Remove collaborator](/api-reference/remove-collaborator). The owner's entry can have the ID `owner`, which isn't a real ID.
  - `email` string, required: Email of the collaborator.
  - `full_name` string, nullable: Full name of the collaborator, or `null` if none is set.
  - `profile_image_url` string, nullable: URL of the collaborator's Base44 profile image, or `null` if they don't have one.
  - `profile_slug` string, nullable: Slug of the collaborator's public Base44 builder profile, or `null` if they don't have one.
  - `is_owner` boolean: Whether the collaborator owns the app.
  - `is_pending` boolean: Whether the collaborator was invited but hasn't opened the app in Base44 yet.
  - `is_guest` boolean: Whether the collaborator is a guest in the app's workspace rather than a member.
  - `collaborator_source` 'workspace', nullable: `workspace` when the collaborator joined because the app is open to everyone in its workspace, or `null` when they were invited.
