# Link an agent to an analysis group

> POST https://api.nabrah.ai/api/ext/analysis/{analysis_group_id}/agent

Group: Analysis groups. Page: https://www.nabrah.ai/en/docs/api-reference/analysis-groups/link-an-agent-to-an-analysis-group

Links a single agent to the analysis group identified by `analysis_group_id` and returns the new `link_id`. This is the analysis-side counterpart to the agent linking endpoints and is convenient when you want to attach one specific agent. The agent must already exist (create it with POST /api/ext/agent). Save the returned `link_id` to unlink later via DELETE /api/ext/analysis/link/{link_id}.

## Where the IDs come from

- **Path and body IDs**: `analysis_group_id` (path) comes from GET /api/ext/analysis. `agent_id` (body) comes from GET /api/ext/agent.

## Response shape

- **link_id**: Returns `{ "link_id": "..." }`. Use this to remove the link with DELETE /api/ext/analysis/link/{link_id}. To link many agents at once, use POST /api/ext/analysis/{analysis_group_id}/agents instead. Fields: `link_id`.

## Authorization

- `X-API-Key` (string, header, required): your workspace API key.

## Path parameters

- `analysis_group_id` (string, required): UUID of the analysis group to link an agent to. Get this from GET /api/ext/analysis or from the create response (POST /api/ext/analysis).

## Body (application/json)

### Example: Link agent

Link one agent to this analysis group.

```json
{
  "agent_id": "018f3a2b-9c4d-7e1a-bf52-0a1b2c3d4e5f"
