What is Plugins in Dynamic 365?

Step 3: Register a Plugin

To register the plugin with Dynamics 365, we can utilize the Plugin Registration Tool by installing it with NuGet or by using XRM Toolbox Plugin Registration.

Start the process by entering all necessary connection information to establish a connection with the required Dynamics 365 organization. While registering new plugin step, we select Primary Entity and the Message activities (Create, Update, Delete, Associate, and Disassociate) for the plugin that is being Created/Updated.

How to  Call third party webapi from plugin in Dynamics 365 .Net?

o call a third-party web API in a .NET plugin and handle the JSON response using Newtonsoft.Json (Json.NET), follow these steps:

Steps to Implement

Install Newtonsoft.Json: Add the Newtonsoft.Json NuGet package to your project if it's not already installed. You can install it via the Package Manager Console:
shell
Copy code
Install-Package Newtonsoft.Json

1. Set Up HttpClient: Use HttpClient to send requests to the API. Configure headers, including any necessary authentication.

2. Define Model Classes: Define C# classes that map to the JSON response structure. This allows you to deserialize JSON into strongly typed objects.

3. Make the API Request and Deserialize JSON:

   • Send the API request.

   • Deserialize the JSON response using JsonConvert.DeserializeObject<T>().

4. Handle Errors: Use try-catch to manage exceptions, such as network issues or JSON parsing errors.

Example Code

using Microsoft.Xrm.Sdk;

using Microsoft.Xrm.Sdk.Messages;

using Microsoft.Xrm.Sdk.Query;

using Microsoft.Xrm.Sdk.Workflow;

using Newtonsoft.Json;

using System;

using System.Net.Http;

namespace PARS.BasePlugin

{

    public class APICALL: IPlugin

    {

        public void Execute(IServiceProvider serviceProvider)

        {

            //IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            // Get a reference to the Organization service.

            IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

            IOrganizationService service = factory.CreateOrganizationService(context.UserId);

            ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

            Entity target = null;

            try

            {

                if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

                {

                    target = context.InputParameters["Target"] as Entity;

                }

                if (target == null)

                    return;

                if (context.MessageName.ToLower() == "update")

                {

                    #region Call API

                    try

                    {

                        var client = new HttpClient();

                        var request = new HttpRequestMessage(HttpMethod.Post, "APIURL" );

                        var json = JsonConvert.SerializeObject(apiparameters);

                        var content = new StringContent(json, UnicodeEncoding.UTF8, "application/json");

                        request.Content = content;

                        var response = client.SendAsync(request).Result;

                        apiresponse = JsonConvert.DeserializeObject<T>(response.Content.ReadAsStringAsync().Result);

                        if (!response.IsSuccessStatusCode)

                            throw new Exception($"Http Status Code: {response.StatusCode}");

                    }

                    catch (Exception ex)

                    {

                        throw new Exception($"Error in API Call Message : {ex.Message}");

                    }

                    #endregion

                }

            }

            catch (Exception ex)

            {

                throw new InvalidPluginExecutionException(ex.Message);

            }

        }

    }
