A prefill token stores answers for a meeting’s booking form. Add it to a booking link as ?prefill_token=<token> to open the form already filled in, without putting personal data in the link. Tokens expire one month after they are created. A token is as sensitive as the answers it holds, so do not share it publicly. For fields and response details, see the API reference. Sample output on this page uses --json.

Create a prefill token

This command creates a prefill token. Use this when you want to send a client a booking link with the form already filled in.
Pass one of --data or --json-file. Both hold a JSON object keyed by the field code of each booking form question.
