Start a Process Instance

Learn how The task helps you to start a process instance.

Use this API to start a workflow process instance. By default, Reltio allows you to start up to 15,000 processes a day in a given tenant. The API returns a 429 HTTP response status code if you exceed this number of processes.

For more information, see Job Throttling and Queuing.

If you want to reduce this daily request threshold, for example, to manage your load predictions and optimize resource utilization, contact Reltio Support.
