I tested this url in the tool PostMan en it works. So please keep your Flows private and secure. It works the same way as the Manually trigger a Flow trigger, but you need to include at the end of the child Flow a Respond to a PowerApp or Flow action or a Response action so that the parent knows when the child Flow ended. THANKS! Hi, anyone managed to get around with above? For information about how to call this trigger, review Call, trigger, or nest workflows with HTTPS endpoints in Azure Logic Apps. The following table has more information about the properties that you can set in the Response action. If you make them different, like this: Since the properties are different, none of them is required. In the trigger's settings, turn on Schema Validation, and select Done. The trigger returns the information that we defined in the JSON Schema. How do you access the logic app behind the flow? Power Platform and Dynamics 365 Integrations. Here is the trigger configuration. Under the search box, select Built-in. Heres an example of the URL (values are random, of course). If you continue to use this site we will assume that you are happy with it. Please refer my blog post where I implemented a technique to secure the flow.
