API calling from C# Using Connection

(0) ShareShare
ReportReport
Posted on by Community member 2
Hello everyone,
I'm relatively new to the Dynamics world and currently facing a challenge. I've created a new custom connector with OAuth 2.0 and successfully added some connections to it. Now, my goal is to execute an action of the custom connector using C# code. Is this possible, and if so, how can I achieve it?
After successfully calling the API and obtaining the response, my next step is to send this response to a PowerApps Component Framework (PCF) component to display the data. Any guidance or assistance on how to proceed would be greatly appreciated.
Thank you!

    Hi ,

    Yes you can call the custom connector using C# as shown in below code snippet:
     
    
    static async Task CallConnector(string accessToken)
    {
        // Construct HTTP request
        var request = new HttpRequestMessage
        {
            Method = HttpMethod.Post,
            RequestUri = new Uri("https://URLofyourconnector/action"),
            Headers =
            {
                { "Authorization", $"Bearer {accessToken}" },
                { "Accept", "application/json" },
                // Add other required headers if needed
            },
        };

        var response = await httpClient.SendAsync(request);
        if (response.IsSuccessStatusCode)
        {
            // Process successful response
            var responseBody = await response.Content.ReadAsStringAsync();
            Console.WriteLine($"Response: {responseBody}");
        }
        else
        {
            Console.WriteLine($"Error: {response.StatusCode}");
        }
    }
    Now, to pass this response to PCF control, You need to setup a bound parameter and from C# code set that bound parameter. But PCF Control need to refresh manually to get the record.
     
    But I would suggest if you want to use response in PCF control then directly call the action inside PCF control.
     
    Thank You,
    Pradeep Rai.
