The first workflow will trigger the next workflow. * Have your **API key** at hand. If you don't have it, contact your organization admin, or, if you're an admin, generate the key in Next Matter by going to **Company > Next Matter API keys**. * Note down the ID of the workflow that will be triggered with the first workflow. You can get the ID by clicking the follow-up workflow and copying the number from the URL in your browser. Image of the Next Matter URL with workflow ID ## Workflow overview 1.

To do that, delete `WORKFLOW_ID` and replace it with the real ID of the follow-up workflow that you have copied from the URL in your browser.

Decide what should happen if the step fails (**On Failure**). 5. Save your changes. Remember to delete the step with instructions that's added to the template. If you don't want to send data from the first to the follow-up instance, delete the **Send data** step as well.
