# Candidate additional fields

> Create custom fields to store extra Candidate details and keep them in sync with your ATS.

Additional fields let you store extra details on every Candidate's profile. For example, you can track an internal status or keep your ATS Candidate ID next to the interview record.

## Limits

* You can create up to 50 fields.
* Field names can be up to 120 characters and must be unique.
* Descriptions can be up to 1,000 characters.

## Fill in field values

You fill in field values from a Candidate's interview report. See [Candidate report](/interview-automation/candidate-report).

## Keep fields in sync with your ATS

Your technical team can connect these fields to your ATS with a [custom integration](/platform/api-integration/overview). This lets you:

* Keep external IDs, such as a Greenhouse Candidate ID, next to the interview record.
* Use field values to organize Candidate records in your connected tools.
* Flag Candidates automatically based on steps in other tools.

<Note>
  Only Owners can create additional fields.
