### Digital Reference Check

**Digital Reference Check**

**Identifier:** `DIGITAL_REFERENCE_CHECK_1`

A Digital Reference Check gathers information about an applicant's personal character, reliability, and past work performance directly from their nominated referees. Referees receive an online questionnaire via email, featuring either a preset or custom list of questions tailored to your organisation's hiring needs. Their responses are collected digitally and returned in a clear, concise report. Referees receive a maximum of one email reminder per day for five days (a total of five reminders) starting the day after the initial invitation. The system allows 14 days for responses — after which, the check will expire and the questionnaire link will no longer be valid.

**Note:** This check is ordered via invite or through a parent check. Applicant data is collected via the invite form and is not sent in the API request body.

### Response

**201 Created** — Successfully ordered. Use the returned `id` to retrieve the full case via `GET /api/public/cases/{id}/`.
