Create a To-Do

Lets you create a new to-do type task. There are 2 ways to use this API –

  • You can create a task and associate it with a lead by passing the “RelatedEntity” parameter as “1” and then passing the “LeadId” as the value for the “RelatedEntityId” parameter.
  • You can create a task without associating it with a lead. In this case, pass the “RelatedEntity” parameter as “0” and don’t pass any value for the “RelatedEntityId” parameter.

You can either provide the “OwnerId” or “OwnerEmailAddress” in the JSON body. The “TaskType” is the type of task you want to create. To retrieve the list of task types, use the Get list of Task Types API.

Note: The “Due Date” and “EndDate” parameters are optional. If you don’t pass them, the due date and end date will be taken as the current day.
