Connect to Webflow 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 API Driver for ADO.NET can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Webflow 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 Webflow using standard SQL queries.

Install the CData API Driver for ADO.NET

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

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

Create a Webflow-Connected Blazor App

Start by creating a Blazor project that references the CData API Driver for ADO.NET

1. Create a Blazor project on Visual Studio.
👁 Create a Blazor app project.

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.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).
👁 Reference ADO.NET for Webflow .dll in the Blazor app.

SELECT Webflow Data from the Blazor App

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

   Authentication

   Webflow uses OAuth 2.0 authentication to ensure secure access to sites, CMS collections, e-commerce data, and other resources. This authentication method allows you to securely connect to your Webflow workspace and manage resources with proper authorization.

   OAuth 2.0 Setup and Configuration

   Step 1: Create a Webflow OAuth Application

   To set up OAuth authentication:

   1. Visit the Webflow Developer Portal
   2. Navigate to "Apps & Integrations" in your Webflow account
   3. Click "Register an App" to create a new OAuth application
   4. Configure the application name, description, and redirect URI (CallbackURL)
   5. Copy the Client ID and Client Secret for use in your connection

   Required Connection Properties

   • AuthScheme: Set this to OAuth (required)
   • OAuthClientId: Client ID from your Webflow OAuth application (required)
   • OAuthClientSecret: Client secret from your Webflow OAuth application (required)
   • CallbackURL: Redirect URI specified in your OAuth application (required)
   • InitiateOAuth: Set to GETANDREFRESH for automatic token management (recommended)

   Required OAuth Scopes

   The Webflow API Profile requires the following OAuth scopes:

   • sites:read - Read access to site information and configuration
   • pages:read - Read access to site pages
   • cms:read - Read access to CMS collections and items
   • forms:read - Read access to forms and form submissions
   • assets:read - Read access to media assets and folders
   • ecommerce:read - Read access to products, orders, and inventory
   • authorized_user:read - Read access to the authorized user

   For example: Profile=C:\profiles\Webflow.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

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

    @page "/"
    @using System.Data;
    @using System.Data.CData.API;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (APIConnection connection = new APIConnection(
    "Profile=C:\profiles\Webflow.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;"))
    {
    var sql = "SELECT , FROM Sites WHERE Id = 'your_site_id'";
    var results = new DataTable();
    
    APIDataAdapter dataAdapter = new APIDataAdapter(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 Webflow data as an HTML table in the Blazor app. 👁 Query Webflow from Blazor app.
