For our new friends:

Logto is an Auth0 alternative designed for modern apps and SaaS products. It offers both Cloud and Open-source services to help you quickly launch your identity and management (IAM) system. Enjoy authentication, authorization, and multi-tenant management all in one.

We recommend starting with a free development tenant on Logto Cloud. This allows you to explore all the features easily.

In this article, we will go through the steps to quickly build the WeCom sign-in experience (user authentication) with WordPress plugin and Logto.

Prerequisites

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Traditional web application, simply follow these steps:

  1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button. Get started
  2. In the opening modal, click the "Traditional web" section or filter all the available "Traditional web" frameworks using the quick filter checkboxes on the left. Click the "WordPress" framework card to start creating your application. Frameworks
  3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate WordPress with Logto​

Install the plugin​

  1. Go to Plugins > Add New.
  2. Search for "Logto", or enter https://wordpress.org/plugins/logto/ in the search box.
  3. Click Install Now.
  4. Click Activate.

Configure the plugin​

Now you should be able to see the Logto menu in your WordPress admin panel sidebar. Click Logto > Settings to configure the plugin.

note:

You should have a traditional web application created in Logto Console before configuring the plugin. If you haven't created one, please refer to Integrate Logto into your application for more information.

The minimum configuration to get started for the plugin is:

  • Logto endpoint: The endpoint of your Logto tenant.
  • App ID: The app ID of your Logto application.
  • App secret: One of the valid app secrets of your Logto application.

All values can be found on the application details page in Logto Console.

After filling in the values, click Save Changes (scroll down to the bottom of the page if you can't find the button).

Configure redirect URI​

The redirect URI is the URL to which Logto will redirect users after they have authenticated; and the post sign-out redirect URI is the URL to which Logto will redirect users after they have logged out.

Here's a non-normative sequence diagram to illustrate the sign-in flow:

Here's how the sign-out flow looks like in a non-normative sequence diagram:

To learn more about why redirect is needed, see Sign-in experience explained.

In our case, we need to configure both redirect URIs in your Logto Console. To find the redirect URI, go to the Logto > Settings page in your WordPress admin panel. You'll see the Redirect URI and Post sign-out redirect URI fields.

  1. Copy the Redirect URI and Post sign-out redirect URI values and paste them into the Redirect URIs and Post sign-out redirect URIs fields in your Logto Console.
  2. Click Save changes in Logto Console.

Checkpoint: Test your WordPress website​

Now you can test your Logto integration in your WordPress website:

  1. Open an incognito browser window if needed.
  2. Visit your WordPress website and click the Log in link if applicable; or directly visit the login page (e.g., https://example.com/wp-login.php).
  3. The page should redirect you to the Logto sign-in page.
  4. Complete the sign-in or sign-up process.
  5. After successful authentication, you should be redirected back to your WordPress website and logged in automatically.
  6. Click the Log out link to log out of your WordPress website.
  7. You should be redirected to the Logto sign-out page, then back to your WordPress website.
  8. You should be logged out of your WordPress website.

Add WeCom connector​

To enable quick sign-in and improve user conversion, connect with WordPress as an identity provider. The Logto social connector helps you establish this connection in minutes by allowing several parameter inputs.

To add a social connector, simply follow these steps:

  1. Navigate to Console > Connectors > Social Connectors.
  2. Click "Add social connector" and select "WeCom".
  3. Follow the README guide and complete required fields and customize settings.
Connector tab
note:

If you are following the in-place Connector guide, you can skip the next section.

Set up WeCom app​

Get started​

Sign in to WeCom WebUI with an admin account or click Manage the enterprise(įŽĄį†äŧä¸š) from the WeCom app.

In the "App Management" tab, scroll the page down and click "Create an app".

Fill in the appropriate information according to your app. Then create.

Now we have the Agent ID (NOT APPID) and Secret.

Website info​

Set the things you need on this page. It would be like:

  • Allowed users: who can see this app
  • App Homepage: Your app homepage. E.g., logto.io/demo-app

Important There are three items on this page regarding the "Developer API(åŧ€å‘者æŽĨåŖ)".

  1. Web Authorization and JS-SDK;
  2. Log in to via authorization by WeCom;
  3. Enterprise Trusted IP;

Fill them according to the guide of WeCom.

Corp ID​

If you are familiar with WeChat development, you may notice that the use of Corp ID is the same as APP ID.

You can find the Corp ID at the bottom of the "My Enterprise(我įš„äŧä¸š)" tab page. It seems like ww**** .

Configure the connector​

So we have the Agent ID, Secret, and Corp ID.

Let's complete the form for the connector.

You can leave the Scope field blank as it is optional. Alternatively, you can fill in snsapi_base or snsapi_privateinfo.

Save and done

Test WeCom connector​

That's it. The WeCom connector should be available now. Don't forget to Enable social connector in sign-in experience.

Save your configuration​

Double check you have filled out necessary values in the Logto connector configuration area. Click "Save and Done" (or "Save changes") and the WeCom connector should be available now.

Enable WeCom connector in Sign-in Experience​

Once you create a social connector successfully, you can enable it as a "Continue with WeCom" button in Sign-in Experience.

  1. Navigate to Console > Sign-in experience > Sign-up and sign-in.
  2. (Optional) Choose "Not applicable" for sign-up identifier if you need social login only.
  3. Add configured WeCom connector to the "Social sign-in" section.
Sign-in Experience tab

Testing and Validation​

Return to your WordPress plugin app. You should now be able to sign in with WeCom. Enjoy!
