API testing from test complete

Here is an example function written in JavaScript using the TestComplete aqHttp Object for direct testing.  It's very basic but you should be able to build it out from here.

Hmm... your statement above not correct: both SoapUI and ReadyAPI  integrate with TestComplete

If you have the Web Module,  SoapUI is free and supported by SmartBear.  ReadyAPI is Smartbear's paid option and is better as far as use and capability.  Otherwise you will need to use a shell call to the TestRunner and parse StdOut.

function sendGetRequest() 
{
  let resourcePath = "https://api.anycompany.com/InventoryManagement/ReceivingGridSelect"
  let resourceQuery = "?PurchasingDocument=21967";
  let url = resourcePath + resourceQuery;
  try 
  {
    // Send GET request
    let response = aqHttp.CreateRequest("GET", url, false).Send();
    // Check for successful response
    if (response.StatusCode === 200) 
    {
      // Parse JSON response
      let allData = JSON.parse(response.Text);
      Log.Message("Total records received: " + allData.length);
      // Process each record
      allData.forEach((record, index) => {
        Log.Message("Record " + (index + 1) + ": " + JSON.stringify(record));
      });
    } 
    else 
    {
      Log.Error("Failed to fetch data. Status code: " + response.StatusCode);
    }
  } 
  catch (error) 
  {
    Log.Error("Error during request or data processing: " + error.message);
  }
}

Example data returned from this function.

You can follow the following reference TestComplete REST APIs | TestComplete Documentation

Also, see https://support.smartbear.com/testcomplete/docs/working-with/integration/ready-api/index.html 

For testing APIs I suggest using dedicated software for that.

We switched over to Bruno for all api tests,

It's very easy to use and open source software.

However if you just need to call 1 or 2 endpoints then that is possible from within TestComplete.
