Add information to custom fields in Apollo. Your custom fields are unique to your team's Apollo account. This means that the examples in this documentation may not work for your testing purposes. To utilize this parameter successfully, call the Get a List of All Custom Fields endpoint and identify the id value for the custom field, as well as the appropriate data type. For example, if a custom field accepts picklist entries, you need to pass the accompanying id value for the picklist entry that you want to use as the input value. Example : When the Get a List of All Custom Fields endpoint returns an id of field: * "60c39ed82bd02f01154c470a" (datetime) then the value passed should be: {"60c39ed82bd02f01154c470a": "2025-08-07"}
