A trigger is an event that starts a flow. In Power Automate, you can use triggers to start a flow when something happens in an envelope, a recipient, or a deliverable.For example, you can start a flow when a deliverable (the signed document) is generated, or when an email to a recipient bounces.
Most electronic signature workflows use two flows:
A flow that creates an envelope, usually triggered by an event in another app (for example, when a new customer is added to a CRM).
A second flow that runs when the envelope is completed. It retrieves the deliverable (the signed document) and uses it—such as storing it in a document repository or sending it to a supervisor.
For the second flow, use the When a deliverable is generated trigger. This trigger runs when the envelope is completed and the deliverable PDF is created. You can then retrieve the PDF and use it in your flow.
The When a recipient is completed trigger runs when a recipient finishes their part of the signing process.You can use it to start a flow that sends a notification or updates another system (such as a SharePoint list).
