# Team API

> API endpoints for team invitation management

ProStack includes API endpoints for managing team invitations, allowing users to accept or reject invitations to join teams.

## Team Invitation Endpoints

### Accept Team Invitation

<CodeGroup>
  ```bash Request theme={null}
  GET /api/team/accept-invitation?invitationId=inv_123456
  ```

  ```json Response theme={null}
  // On success, redirects to dashboard with welcome message
  ```
</CodeGroup>

This endpoint accepts a team invitation and adds the authenticated user to the team. If the user is not authenticated, they will be redirected to the sign-in page with a callback to the accept invitation URL.

### Reject Team Invitation

<CodeGroup>
  ```bash Request theme={null}
  GET /api/team/reject-invitation?invitationId=inv_123456
  ```

  ```json Response theme={null}
  // On success, redirects to dashboard
  ```
</CodeGroup>

This endpoint rejects a team invitation, removing it from the user's pending invitations.

## Error Handling

If an error occurs during the invitation process, the API will return an HTML response with an error message:

```html theme={null}
<h3>Error message</h3>
<p>Try again later or contact support.</p>
```

Common error scenarios:

* Invalid invitation ID
* Expired invitation
* User already in team
* Insufficient permissions

## Authentication Required

Both endpoints require authentication. If the user is not authenticated when accepting an invitation, they will be redirected to:

```
/auth/sign-in?callback=<encoded_accept_invitation_url>
```
