# Set Agent as Callback

# Set Agent as Callback

Configure an inbound agent to handle callbacks from one or more outbound source agents. When a contact previously called by a source agent dials back, the call is routed to this agent (assuming the agent owns the dialed number).

## Endpoint

```
POST /api/v1/agents/{agent_id}/callback
```

## Path parameters

<ParamField path="agent_id" type="string" required>UUID of the inbound agent. Must have `direction: "inbound"`.</ParamField>

## Request headers

<ParamField header="Authorization" type="string" required>
  Bearer token. Format: `Bearer talq_your_environment_token_here`
</ParamField>

<ParamField header="Content-Type" type="string" required>
  Must be set to `application/json`
</ParamField>

## Request body

<ParamField body="source_agent_ids" type="array" required>
  Array of outbound agent UUIDs whose contacts should route to this callback agent on inbound returns. Must contain at least one entry.
</ParamField>

## Examples

  ```bash theme={null}
  curl -X POST "https://app.talkover.ai/api/v1/agents/agent-uuid-1/callback" \
    -H "Authorization: Bearer talq_your_environment_token_here" \
    -H "Content-Type: application/json" \
    -d '{
      "source_agent_ids": ["agent-uuid-2", "agent-uuid-3"]
    }'
