HTTP POST Requests using Microsoft Flows

Introduction:

In this blog we will demonstrate the working of HTTP Request -Response in Microsoft Flows.

Implementation:

Step 1:  In our example we will make a POST call to our Microsoft Flow so that we can further apply some logic in Flows. The POST request contains the following data.

JSON:

[{
"name": "TestName",
"Address": "TestAddress"
}]

Now we can use online editor tools to create a schema file of the above JSON. (https://jsonschema.net/). Submit the JSON data and the schema will be generated as shown below.

Step 2: Now we go to Microsoft Flows,create a new flow and add the first step as “Request” as shown below:

Step 3: We then paste the JSON schema that we earlier saved

In the “Show advanced”  options we have to add the following details:

Once that is done we select a condition. In our example we  will pass a JSON Array hence we will loop through each item. Here we add a apply to each condition as shown

And we add a dynamic output from the previous stage

Then inside the apply to each loop we can add any action and take the values passed from the POST request. For this example I create a new account in CRM with the name and address provided as shown below

Step 4: Now when we save this flow a URL is generated in the First HTTP Request step. We test the flow by calling this URL from Postman. The URL generated is show below

Step 5: Now we open Postman and write the request as shown below

Also in the Header section we add the following details

Step 6: Once we click on Send the two records are created in CRM as shown below

Conclusion:

We can call this URL from outside Dynamics CRM as well and using this we explore many more functionalities provided by Microsoft Flows to achieve the desired outcome.
