Connect to Marketo Data from Blazor Apps

Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.

The CData ADO.NET Provider for Marketo can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Marketo data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to Marketo using standard SQL queries.

Install the CData ADO.NET Provider for Marketo

CData ADO.NET Providers allow users to access Marketo just like they would access SQL Server, using simple SQL queries.

Install the Marketo ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Marketo ADO.NET Data Provider."

Create a Marketo-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Marketo

1. Create a Blazor project on Visual Studio.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.Marketo.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Marketo\lib etstandard2.0).

SELECT Marketo Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a MarketoConnection object, set the connection string:

   Both the REST and SOAP APIs are supported and can be chosen by using the Schema property.

   For the REST API: The OAuthClientId, OAuthClientSecret, and RESTEndpoint properties, under the OAuth and REST Connection sections, must be set to valid Marketo user credentials.

   For the SOAP API: The UserId, EncryptionKey, and SOAPEndpoint properties, under the SOAP Connection section, must be set to valid Marketo user credentials.

   See the "Getting Started" chapter of the help documentation for a guide to obtaining these values.

   For example: Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;

3. The code below creates a simple Blazor app for displaying Marketo data, using standard SQL to query Marketo just like SQL Server.

         @page "/"
         @using System.Data;
         @using System.Data.CData.Marketo;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (MarketoConnection connection = new MarketoConnection(
                   "Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;"))
                 {
                     var sql = "SELECT Email, AnnualRevenue FROM Leads";
                     var results = new DataTable();
         
                     MarketoDataAdapter dataAdapter = new MarketoDataAdapter(sql, connection);
                     dataAdapter.Fill(results);
         
                     <table class="table table-bordered">
                         <thead class="thead-light">
                             <tr>
                                 @foreach (DataColumn item in results.Rows[0].Table.Columns)
                                 {
                                     <th scope="col">@item.ColumnName</th>
                                 }
                             </tr>
                         </thead>
                         <tbody>
                             @foreach (DataRow row in results.Rows)
                             {
                                 <tr>
                                     @foreach (var column in row.ItemArray)
                                     {
                                         <td>@column.ToString()</td>
                                     }
                                 </tr>
                             }
                         </tbody>
                     </table>
                 }
             </div>
         </div>
       

4. Rebuild and run the project. The ADO.NET Provider renders Marketo data as an HTML table in the Blazor app.

   At this point, you have a Marketo-connected Blazor app, capable of working with live Marketo data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live Marketo data in your Blazor apps today.
