Depending on the EMR system connected to the account, additional fields beyond the base required fields may be required. If a conditionally required field is missing, the API will return a 400 error specifying the missing field.

​
Request Parameters

​
Required Fields

These fields are always required regardless of the connected EMR:
  • description (string, required): Task description/body content
  • patient_mrn (string, required): Medical Record Number (MRN) of the patient

​
Conditionally Required Fields

Depending on the connected EMR, some combination of the following fields will also be required:
  • subject (string, conditionally required): Task title/subject line
  • assignee_user_id (string, conditionally required): EMR user ID to assign the task to
  • phone_call_type_id (string, conditionally required): Identifier for the phone call type
  • notify_list (string[], optional): List of user identifiers to notify about the task. Must be an array of strings if provided.

Error Responses

​
Missing Required Field

If a required or conditionally required field is missing, the API returns a 400 with the specific field name:
