GET/v1/calls/{call_id}

Parameters

call_id
Location
Path · required
Description
The UUID returned when the call was created.

Authorization

Header · required
Description
Bearer <API_KEY>, from the same Agent Project as the call.

No request body or idempotency key is needed for this operation.

This reads saved state. Use Sync a call when you need to refresh progress from the calling service.

Example request

Use the call ID returned by creation. The cURL example reads it from CALL_ID.

For cURL, use Bash and set these variables in the same terminal. CALL_ID is the call UUID returned by create, not the idempotency key. The Python tab prompts for both inputs itself.

Bash setup
read -rsp "Cleo API key: " CLEO_API_KEY; echo
export CLEO_API_KEY
read -rp "Call ID returned by create: " CALL_ID
export CALL_ID
curl --fail-with-body -X GET \
  "https://api.cleolabs.com/v1/calls/$CALL_ID" \
  -H "Authorization: Bearer $CLEO_API_KEY" \
  -H "User-Agent: CleoDocs/1.0"

Response

Returns 200 OK with the call object. If the call does not exist or belongs to a different Agent Project, the API returns 404 call_not_found.
