What this does

When you send a Get CDR request with a CDR ID, Voiso returns one CDR record.

The response is polymorphic, meaning the type field determines the shape of the data object:

call
conversation
hlr_lookup
sms

When to use it

Retrieve full details for a record returned by Get list of CDRs
Inspect type specific details stored in data
Troubleshoot a specific interaction using a single CDR ID

Endpoint


GET /api/v4/reporting/cdrs/{cdr_id}

Path parameters

cdr_id
The unique identifier of the CDR record (UUID).

Example request

curl -X GET "https://{cluster_id}.voiso.com/api/v4/reporting/cdrs/775a5558-59a6-4468-a502-0deef2a3315d" \
  -H "Authorization: Bearer <contact_center_api_key>" \
  -H "Content-Type: application/json"

Notes

The type field determines which fields exist inside data.
Some fields can be null depending on the interaction type and routing path.

Troubleshooting

404 Not found

This usually means the CDR ID does not exist, or you do not have access to it.

What to check:

Confirm the ID using Get list of CDRs.
