You can use the RunAJob utility to run jobs and check job status instead of calling the IDMC REST API directly.
Before you run a taskflow using the RunAJob utility, publish the taskflow. Then, in the taskflow designer, enter values in the Allowed Users and Allowed Groups fields.
To run a taskflow that's deployed to a Customer Managed Secure Agent group with the RunAJob utility, use your second password to authenticate. Don't use your IDMC password.
Create a separate password to allow Customer Managed Secure Agents to authenticate API calls. For more information about how to set a second password, see Runtime Environments in the Administrator help.
For information about running a taskflow using the RunAJob utility, see REST API Reference.
