Summary

Create a custom field in RD Station CRM for a contact, deal, organization, or product. The operation sends the field attributes in a top-level API request body and returns the API response.

Inputs

  • Authentication — Choose Access Token (API V1) or OAuth2 (API V2); Access Token is the default.
  • Label (required) — Human-readable name for the field.
  • Type (required) — Value type: date, multiple choice, option, or text. Defaults to text.
  • Entity (required) — Record type the field belongs to: contact, deal, organization, or product. Defaults to contact.
  • Allow New — Whether users can add choices beyond the predefined options; applies to option and multiple choice fields.
  • Options — Comma-separated choices for option and multiple choice fields. The operation splits this string into an array.
  • Order — Display position; lower numbers appear first. Defaults to 0.
  • Required — Whether the field must be filled when saving a record. Defaults to false.
  • Unique — Whether each record must have a distinct value for this field. Defaults to false.

Output shape

A single custom-field record returned by the API.

The request body is sent at the top level, without a custom_field wrapper. The source shows comma-separated options are converted to an array; fields meant for choice types may not be relevant for other types.
