Sending dataverse table data in HTTP post

Posted on by CU27011611-0

I am setting up a flow to trigger when a row is added to a table. Specifically, when a new session is added for an event in Dynamics 365.

The first step in the flow is a HTTP post to an API endpoint. What I would like to do is include details of that event just added - specifically the date and time - in said HTTP post as form data.

I have done many, many searches and found how to include file content and dynamic data in a HTTP post, as well as how to handle any data returned from it. But not any way of sending data from the table that triggers the flow in the first place. It seems like is such an obviously useful operation but the means of doing it has just been bizarrely elusive. Any help is sincerely appreciated.

It's very easy to insert data values from a "When a row is added, modified or deleted" into any other action downstream in the flow, including an HTTP post.

Is that what you're trying to do, or are you wanting to do something else?

How you format the data depends on the endpoint you're sending to. Here's how you could send some data in a small JSON object:

@Mark Nanneman Thank you so much for your reply.

What you are showing in your screenshots is the kind of thing I expected to be able to set up.

However, I am not seeing the (purple-coloured) 'HTTP API Endpoint' you have in your flow on my list of available actions. I have been attempting to go straight to the (green-coloured) 'HTTP'.

Is the 'HTTP API Endpoint' step critical to being able to read/access the data from the added or modified table row at the 'HTTP' step? Is access to this action limited according to user role/privileges or license/subscription type?

Presently if I use the forward slash inside the text area for the HTTP request body to add dynamic data (which is how I understand you are adding 'Name' and 'FlowRunId' to yours) it says 'no content available'.

Thanks once again!
