API Proxy to Serverless

Azure Serverless (Functions and Logic Apps) can be configured to benefit from the advantages of Azure API Management.

Azure Functions

Create a simple function that is Triggered by an HTTP Request

Example:

    //string[] strColors = { "blue", "lightblue", "darkblue" };
    string[] strColors = { "green", "lightgreen", "darkgreen" };

    Random r = new Random();
    int rInt = r.Next(strColors.Length);

    return  (ActionResult)new OkObjectResult(strColors[rInt]);

Lets add the function to Azure API Management. In the API blade select [+Add API] and the [Function App] tile

Select the [Browse] button to get a list of Functions in the subscription

Select the Function App and then the Function

Amend the Names / Descriptions, URL suffix and select the Products

As previously add CORS policy
Validate the function works - either from the Azure management portal or the developer portal

Azure Logic Apps

Create a simple logic app that is Triggered by an HTTP Request

Example:

Use the following sample message to generate the schema of the Request body payload. By specifying the schema, the individual fields (in this case msg) can be extracted and referred to in the subsequent logic
