Postman External Trigger

Here’s a screen shot of the instructions in the Helium Docs along with a link to the page.

In this example, I can manually post the information from the Postman console. But I’m looking for a way to trigger this post to happen automatically. Google sheets has a tool that will automatically post data to an endpoint. But without a trigger on the Postman side, there’s no way to tell the program to initiate the post.
