Summary

Given an Activity Number and a Task Group identifier, returns information about the matching Activity Instance. If no Activity Instance is found, a new one is automatically created. The new record is functionally equivalent to an Activity Instance created by an end user via the "Add Activity" button on a Learning Plan Task Group.

If more than 1 matching Activity Instance record is found, or if a new instance cannot be created, an error is returned.

Overview

Given an Activity Number and a Task Group identifier, returns information about the matching Activity Instance. If no Activity Instance is found, a new one is automatically created. (This new record is functionally equivalent to the one created by an end user clicking the Add Activity button on the Task Group).

This is useful when you want to update an existing Activity Instance, if one exists, or create a new one. This API method avoids the need for you to check for existence and conditionally create a new record manually.
 
If more than matching Activity Instance records are found, or if the new instance cannot be created, an error is returned.

Request:
The following arguments are expected in the query string:

ParameterDescription
ActivityNumberRequired - ID label of an activity
LearningPlanInstanceId

Required - ID number of a learning plan instance; normally retrieved using the /API/ActivityInstance/GetOrCreate API.

TaskGroupIdOptional - ID number of a task group
TaskGroupTitleOptional - the name of a task group


You must provide EITHER the TaskGroupId or the TaskGroupTitle, but not both. This information can be obtained by a LearningBuilder admin or by using the administrative features.


Example:
/API/ActivityInstance/GetOrCreate?ActivityNumber=ACT0001&LearningPlanInstanceId=998&TaskGroupId=732

Response:
{"success":true,"ActivityInstanceId":14021,"WorkflowInstanceId":21979}
{"success":false,"errors":["error message goes here"]}
