Note

The HTTP with Microsoft Entra ID (preauthorized) connector enables users to submit requests to any HTTP endpoint that supports Entra ID authentication. As part of our ongoing efforts to enhance security and data privacy, we have reviewed the permissions associated with this connector and are planning to provide improved identity isolation controls.

Currently, the HTTP with Microsoft Entra ID (preauthorized) connector operates through a Microsoft 1st party trusted application. This application includes preauthorization for various Microsoft services, including but not limited to Microsoft Graph, SharePoint, and other Microsoft offerings. This preauthorization empowers the connector to interact with these services using delegated access on behalf of the user. Rest assured that this approach fully respects the user's privileges and does not permit access to data or actions beyond their authorized scope.

With the existing connector, there is no need for administrators to explicitly grant consent for actions to be executed by the application on behalf of the user. However, we released a new version of this connector. The new version of the connector uses a new application without any preauthorization. This allows an administrator to grant discrete consent.

If you wish to restrict the use of this connector, you can leverage the existing Data Loss Prevention (DLP) capabilities. You have the option to create a new policy or update an existing one to block the utilization of this connector. It is important to note that some other connectors and features depend on the HTTP with Microsoft Entra ID (preauthorized) connector. For additional information, click here.

Virtual Network support (Subnet Delegation)

When the connector is used in a Power Platform environment linked to a Virtual Network, limitations apply:

Known Issues and Limitations

  1. The connector encodes the request body into base64 encoding, hence it should be used to call backend services which expect the request body in this format. You cannot use this connector to call a backend service that expects the request body in raw binary format.

  2. If you get an error similar to:

  • { "error": { "code": "Forbidden", "message": "" } }
  • { "error": { "code": "Authorization_RequestDenied", "message": "Insufficient privileges to complete the operation." } } then it could be because this connector has a limited set of scopes.
  • Users may also face pre-authorization errors when connecting to some resources that are not supported.
  • If your scenario requires something more advanced, please use the "HTTP" connector or create a custom connector.
  1. The connector is based on multi-tenant application registration. The application cannot tell what tenant the user is from until the user signs into it. Therefore, we only support specifying resources under users' default tenant ('common').

  2. Resources based on ADFS SSO (Microsoft Entra ID Federation Services for Single Sign-On) are not supported. As a workaround, please use the "HTTP" connector.

  3. When using this connector in a national cloud environment the resource must be their national cloud endpoint equivalent. Attempts to try to connect to public cloud (https://graph.microsoft.com, https://bing.com for example) from most national cloud environments will fail with a pre-authorization error.

  4. The use of cookie authorization request header is not supported in case of on-premises data gateway enabled connection.

  5. The asynchronous pattern based on the response Location header is not supported. Please use Azure Resource Manager connector instead if applicable.

  6. For the ‘HTTP with Microsoft Entra ID’ connector to successfully retrieve data from another service, the app used by the connector must be granted access to the required scope. For details on how to grant the required access to the app, refer to Authorize the app to act on behalf of a signed-in user. If the required access is not granted, you may receive one of the following errors when you attempt to create the connection:

    Consent Required: To enable the HTTP With Microsoft Entra ID connector to access resources on behalf of a signed-in user, grant consent to this application.
    

    Grant Consent

    If a scope (permission) has been granted but not all of the required scopes are included, the creation of the connection will succeed but you will encounter a Forbidden (403) error at runtime. The error details may include additional information such as:

    "code": "Authorization_RequestDenied"
    "message": "Insufficient privileges to complete the operation."
    
    

Authorize the connector to act on behalf of a signed-in user

As a user with the Global Administrator role, you need to create oAuth2PermissionGrants to approve the necessary permissions (scopes) for the required service.

For example, if you are using Microsoft Graph (https://graph.microsoft.com) and need to read calendar information, you can follow the Graph documentation to identify the permissions required (Calendar.Read). By granting the app (used by the connector) the Calendar.Read scope, it will allow the app to access this data from the service on behalf of the user. One important thing to note is that the data that can be accessed by the app is still limited to the data the user has access to in the service. It is not possible to use the Azure Portal to grant consent to this app. For this reason, a PowerShell script has been created by Microsoft to simplify granting consent to the app used by the HTTP with Microsoft Entra ID connector.

Important

PowerShell version 7 or later needs to be installed to run this script.

  1. Download the required PowerShell script from here.

  2. Right-click on the downloaded ManagePermissionGrant.ps1 file and then click Properties.

  3. Click the Unblock checkbox and then click OK.

    Unblock Script

    If you do not check the Unblock checkbox, you will receive an error indicating the script cannot be loaded because it is not digitally signed.

  4. Open a PowerShell command window.

  5. Change the path to the location where you downloaded the script.

  6. Type the following command and press Enter:

    .\ ManagePermissionGrant.ps1
    

    Execute Manage Permission Grant Script

  7. You will be prompted to choose whether to authenticate to Azure Global (recommended) or to select from a list (advanced). If you are not connecting to subscriptions in US Gov, US Gov DoD, China, or Germany, press Enter.

    Cloud Selection

  8. If you have not already, you may be prompted to authenticate to the Microsoft identity platform in a new browser window. Authenticate as a user with the Global Administrator role.

  9. To grant consent to some of the most used services such as Microsoft Graph or SharePoint, press Enter. If the service you need to consent to is not on the list of commonly used apps, use option A.

    Resource and Scope Selection

  10. A dialog will appear. Select the application you want to consent to allowing the connector to act on behalf of a user. You can use the textbox at the top to filter the results.

    Select Application

  11. Click OK.

  12. Select one or more scopes (permissions) you want to consent to and then click OK. Multiple scopes can be selected by pressing and holding the CTRL key while selecting rows.

  13. In the PowerShell window you will be prompted to choose the consent type. You can choose whether to allow the app to act on behalf of any logged in user or if you want to limit the consent to a specific user. If you want to provide consent for all users, press Enter. If you want to provide consent for only a specific user, type N and then press Enter. If you choose to consent for a specific user, you will be prompted to select the user.

  14. If consent for any scopes already exist for the selected resource, you will be prompted to choose if you want to delete the existing grants first. If you want to delete existing grants, type Y and press Enter. If you want to keep the existing grants, press Enter.

  15. A summary of the scopes you selected will be displayed in the PowerShell window. If you want to proceed with granting the selected scopes, type Y and then press Enter.

  16. If the script can grant the consent successfully, you will see a message that script execution completed.
