Create and register SOAP custom connectors in Azure Logic Apps

To integrate SOAP services in your logic app workflows, you can create and register a custom Simple Object Access Protocol (SOAP) connector by using Web Services Description Language (WSDL) that describes your SOAP service. The SOAP connectors work like prebuilt connectors, so you can use them in the same way as other connectors in your logic apps. Currently, SOAP custom connectors don't support one-way operations.


To register your SOAP connector, you need these items:

  • An Azure subscription. If you don't have a subscription, you can start with a free Azure account. Or, you can sign up for a Pay-As-You-Go subscription.

  • Any item here:

    • A URL to a WSDL that defines your SOAP service and the APIs
    • A WSDL file that defines your SOAP service and the APIs

    For this tutorial, you can use our example Orders SOAP Service.

  • Optional: An image to use as an icon for your custom connector

1. Create your connector

  1. In the Azure portal, on the main Azure menu, choose New. In the search box, enter logic apps connector as your filter, and press Enter.

    New, search for "logic apps connector"

  2. From the results list, choose Logic Apps Connector > Create.

    Create Logic Apps connector

  3. Provide details for registering your connector as described in the table. When you're done, choose Pin to dashboard > Create.

    Logic App custom connector details

    Property Suggested value Description
    Name soap-connector-name Provide a name for your connector.
    Subscription Azure-subscription-name Select your Azure subscription.
    Resource group Azure-resource-group-name Create or select an Azure group for organizing your Azure resources.
    Location deployment-region Select the same Azure region as your logic app.

    After Azure deploys your connector, the logic apps connector menu opens automatically. If not, choose your soap connector from the Azure dashboard.

2. Define your connector

Now specify the WSDL file or URL for creating your connector, the authentication that your connector uses, and the actions and triggers that your soap connector provides.

2a. Specify the WSDL file or URL for your connector

  1. In your connector's menu, if not already selected, choose Logic Apps Connector. In the toolbar, choose Edit.

    Edit custom connector

  2. Choose General so that you can provide the details in these tables for creating, securing, and defining the actions and triggers for your SOAP connector.

    1. For Custom connectors, select SOAP for your API Endpoint so you can provide the WSDL file that describes your API.

      Provide the WSDL file for your API

      Option Format Description
      Upload WSDL from file WSDL-file Browse to the location for your WSDL file, and select that file.
      Upload WSDL from URL http://path-to-wsdl-file Provide the URL for your service's WSDL file.
      SOAP to REST Transform APIs in SOAP service into REST APIs.
    2. For General information, upload an icon for your connector. Typically, the Description, Host, and Base URL fields are automatically populated from your WSDL file. But if they're not, add this information as described in the table, and choose Continue.

      Connector details

      Option or setting Format Description
      Upload Icon png-or-jpg-file-under-1-MB An icon that represents your connector

      Color: Preferably a white logo against a color background.

      Dimensions: A ~160 pixel logo inside a 230 pixel square

      Icon background color icon-brand-color-hexadecimal-code

      The color behind your icon that matches the background color in your icon file.

      Format: Hexadecimal. For example, #007ee5 represents the color blue.

      Description connector-description Provide a short description for your connector.
      Host connector-host Provide the host domain for your SOAP service.
      Base URL connector-base-URL Provide the base URL for your SOAP service.

2b. Describe the authentication that your connector uses

  1. Now choose Security so you can review or describe the authentication that your connector uses. Authentication makes sure that your users' identities flow appropriately between your service and any clients.

    By default, your connector's Authentication type is set to No authentication.

    Authentication type

    To change the authentication type, choose Edit. You can select Basic authentication. To use parameter labels other than default values, update them under Parameter label.

    Basic authentication

  2. To save your connector after entering the security information, at the top of the page, choose Update connector, then choose Continue.

2c. Review, update, or define actions and triggers for your connector

  1. Now choose Definition so you can review, edit, or define new actions and triggers that users can add to their workflows.

    Actions and triggers are based on the operations defined in your WSDL file, which automatically populate the Definition page and include the request and response values. So, if the required operations already appear here, you can go to the next step in the registration process without making changes on this page.

  2. Optionally, if you want to edit existing actions and triggers, or add new ones, see an example of editing an API definition.

3. Finish creating your connector

When you're ready, choose Update Connector so you can deploy your connector.

Congratulations! Now when you create a logic app, you can find your connector in Logic Apps Designer, and add that connector to your logic app.

In Logic Apps Designer, find your connector

Share your connector with other Logic Apps users

Registered but uncertified custom connectors work like Microsoft-managed connectors, but are visible and available only to the connector's author and users who have the same Azure Active Directory tenant and Azure subscription for logic apps in the region where those apps are deployed. Although sharing is optional, you might have scenarios where you want to share your connectors with other users.


If you share a connector, others might start to depend on that connector. Deleting your connector deletes all connections to that connector.

To share your connector with external users outside these boundaries, for example, with all Logic Apps users, Certify your connector.


Q: Is the SOAP connector generally available (GA)?
A: The SOAP connector is in Preview, and is not a GA service yet.

Q: Are there any restrictions and known issues for a SOAP connector?
A: Yes, see the SOAP connector restrictions and known issues.

Q: Are there any limits for custom connectors?
A: Yes, see the custom connector limits here.
