Groups API

The Groups API provides endpoints for managing groups and organizations through Zitadel integration.

Implementation Details

Zitadel Integration

All group operations are proxied to Zitadel:

• Groups map to Zitadel organizations
• Members are managed through Zitadel’s org API
• Permissions inherited from Zitadel roles

Data Model

Groups are not stored in BotServer’s database. All data comes from Zitadel:

• Group metadata from Zitadel orgs
• Membership from Zitadel org members
• Permissions from Zitadel policies

Error Responses

All endpoints may return standard error responses:

{
  "error": "Group not found",
  "code": "GROUP_NOT_FOUND",
  "status": 404
}

Common error codes:

• GROUP_NOT_FOUND - Group doesn’t exist
• UNAUTHORIZED - User lacks permission
• MEMBER_EXISTS - User already in group
• MEMBER_NOT_FOUND - User not in group
• ZITADEL_ERROR - Upstream service error

Permissions

Group operations require appropriate Zitadel permissions:

• Create: Organization admin
• Update: Organization owner or admin
• Delete: Organization owner
• List: Authenticated user
• View Members: Group member
• Add/Remove Members: Group admin

Rate Limiting

Group endpoints are rate-limited:

• 100 requests per minute for read operations
• 20 requests per minute for write operations

Best Practices

1. Cache Group Data: Groups change infrequently
2. Batch Operations: Use bulk endpoints when available
3. Handle Zitadel Errors: Gracefully handle upstream failures
4. Validate Permissions: Check user has required role
5. Audit Changes: Log all group modifications
