Create and delete B2C accounts for Dataverse Contact

Today, we’ll be discussing a crucial aspect of B2C account management – the creation and deletion of B2C accounts in response to changes in the Dataverse Contact. This is an important topic for businesses that deal with external Power Pages user (contacts) that want to ensure the security of their records and Power Pages. In this post I will explain how to create or delete B2C accounts that are connected to a Dataverse Contact. So, let’s dive in!

Create a B2C account when a Dataverse Contact is created

Whenever a new contact is created a new B2C account needs to be created automatically that is linked to the contact. This is done thought the email address of the contact and the Azure B2C account id. These automations will limit the amount of manual admin work.

  • Create a new Power Automate flow with the name Create B2C user for Dataverse Contact.
  • Add the Dataverse trigger When a row is added.
  • Set the Change type to Added.
  • Set the Table name to Contacts.
  • Set the Scope to Organization.
  • Create the following 3 variables.
  • You will need to create an Application Registration in the B2C tenant with the following permissions.
Permission typePermissions (from least to most privileged)
Delegated (work or school account)User.ReadWrite.All, Directory.ReadWrite.All
Delegated (personal Microsoft account)
Not supported
ApplicationUser.ReadWrite.All, Directory.ReadWrite.All
  • Store the Client ID, Tenant ID and Secrect in the corresponding variables.
  • Add a HTTP action called HTTP – Delete User to the flow.
  • Set the Method to: Post.
  • Set the URI to the following code.
  • Set the body to the following code.
  • In my scenario the user will not be using the password but the one-time password from B2C. That’s why I have added a guid twice as the password.
  • This call will create an account of the type email address which allows for any valid email to be used. The email does not have to be part of the B2C domain.
  • Parse the JSON response of the HTTP – Create User call.
  • Add the Dataverse action Update a row.
  • Set the Table name to Contact.
  • Set the Row id to the contact id of the trigger.
  • Add the id that was returned by the HTTP call that created the B2C account.
  • Save the flow.

Delete B2C account when Dataverse Contact is deleted

In my scenario I am maintaining the Power Pages contacts within a canvas app, and when a contact is deleted the associated B2C account needs to be deleted too.

  • Create a new Power Automate flow with a Power Apps (V2) trigger with the name Delete B2C users for deleted Dataverse Contact.
  • Add an input Text field names ActiveDirectoryID.
    • This is the Object ID of the Azure B2C Active Directory User connected to the Contact.
  • Create the following 3 variables.
  • You will need to create an Application Registration in the B2C tenant with the following permissions.
Permission typePermissions (from least to most privileged)
Delegated (work or school account)User.ReadWrite.All
Delegated (personal Microsoft account)
Not supported
  • Store the Client ID, Tenant ID and Secret in the corresponding variables.
  • Add a HTTP action called HTTP – Delete User to the flow.
  • Set the Method to: Delete.
  • Set the URI to the following code.
  • Add the PowerApp (V2) parameter ActiveDirectoryID to the end of the URI.
  • Set the Tenant, Client ID and Secret fields with their corresponding variables.
  • Set the Authentication to Active Directory OAuth.
  • Set the Audience to the following code.
  • Save the Power Automate Flow.
  • Open or create a canvas app (Power Apps).
  • Open the Power Automate panel in the canvas app.
  • Add the Delete B2C users for deleted Dataverse Contact Power Automate flow.
  • Add a gallery with the source set to the Dataverse Contact table.
  • Add a recycle bin or other delete Icon to the gallery.
  • Add the following code to the recycle bin icon under OnSelect.
    • This will remove the contact record.
    • Starts the Power Automate Flow and sending the User Name (Users B2C object ID).
    • Notifies the users.
Remove(Contacts, ThisItem);
DeleteB2CuserfordeletedDataverseContact.Run(ThisItem.'User Name');
Notify("Record deleted successfully", NotificationType.Success);
  • Save and publish the canvas app.

Power Platform: Custom administrator and developer role

Custom security roles on Power Platform are mostly used for Dynamics and model-driven apps, but they also work for canvas apps. By default an environment (without a Dataverse database) has two default roles (environment maker and environment admin). However if you create and environment with a Dataverse database, you get the ability to create custom security roles and 10 default roles. I strongly advise not to change the default roles.

Custom administrator role

At the moment of writing this blog it is possible to alter the default environment maker role (not system administrator), but I would not recommend it. Microsoft might push changes to the default roles and overwrite the customizations.

Creating a copy of the system administrator role or the environment maker role and making changes to the copied role, is also not an option. In the background Microsoft sets the CanEdit privilege to the administrator/environment maker role, and if you copy the role the CanEdit privilege is lost. The CanEdit privilege can only be set by Microsoft.

This practically means that creating a custom administrator role is not possible.

Note: Granting a user a role that effects the CanEdit privilege will take a non-specified amount of time to take effect. For example, if you switch from a copied role to a default role, it can take 30 minutes for the change to take effect.

Custom developer role

Creating a custom developer role is possible if you are willing to accept the following scenario. The developer gets an custom security role granting the required privileges, for example the ability to work with solutions and canvas apps but no export privileges. With only this security role the developer cannot access the environment and is missing the hidden CanEdit role.

The CanEdit role can also be granted by being an owner or a co-owner of a canvas app in the environment. If an administrator creates a canvas app and makes the developer co-owner of that app then the developer can access the environment and has the hidden CanEdit role.

Retrieve Dataverse records with JavaScript

When validations or manipulations in a model-driven app are too complex for a business rule you can use JavaScript instead. With JavaScript you can use the Dynamics API to gather information and/or update records. JavaScript only runs on the interface; this means that the validation or manipulation only happen when a user is interacting with the model-driven app.


With retrieveRecord you can retrieve a records form a table if you know the ID.

Xrm.WebApi.retrieveRecord("account", "a8a19cdd-88df-e311-b8e5-6c3be5a8b200", "?$select=name,revenue")

Xrm.WebApi.retrieveRecord("TABLE", "ID", "?$select=COLUMN,COLUMN")

In this example a record from the table accounts is retrieved and the columns name and revenue are returned. If it was successful the results are displayed in the console, if an error occurred then the error message is displayed in the console.

Xrm.WebApi.retrieveRecord("account", "a8a19cdd-88df-e311-b8e5-6c3be5a8b200", "?$select=name,revenue").then(
    function success(result) {
        console.log("Retrieved values: Name: " + + ", Revenue: " + result.revenue);
        // perform operations on record retrieval
    function (error) {
        // handle error conditions


With retrieveMultipleRecords you can retrieve multiple records from a table based on a filtering.

Xrm.WebApi.retrieveMultipleRecords("account", "?$select=name,primarycontactid&$filter=primarycontactid eq a0dbf27c-8efb-e511-80d2-00155db07c77")

Xrm.WebApi.retrieveMultipleRecords("[TABLE]", "?$select=[COLUMN],[COLUMN]&$filter=[COLUMN] eq ID")

In this example three records from the table accounts are retrieved and the columns name is returned. If it was successful the results are displayed in the console, if an error occurred then the error message is displayed in the console.

Xrm.WebApi.retrieveMultipleRecords("account", "?$select=name", 3).then(
    function success(result) {
        for (var i = 0; i < result.entities.length; i++) {
        console.log("Next page link: " + result.nextLink);
        // perform additional operations on retrieved records
    function (error) {
        // handle error conditions

Expand query to get related records

With the $expand options we can retrieve related records of the record that was returned, this works for both retrieveRecord and retrieveMultipleRecords. Expand uses navigation columns (relationship/lookup) to retrieve the related records.

Xrm.WebApi.retrieveRecord("account", "a8a19cdd-88df-e311-b8e5-6c3be5a8b200", "?$select=name&$expand=primarycontactid($select=contactid,fullname)")
Xrm.WebApi.retrieveRecord("[TABLE]", "ID", "?$select=[COLUMN]&$expand=[NAVIGATION COLUMN]($select=[COLUMN],[COLUMN])")

Xrm.WebApi.retrieveMultipleRecords("account", "?$select=name&$top=3&$expand=primarycontactid($select=contactid,fullname)", 3)
Xrm.WebApi.retrieveMultipleRecords("[TABLE]", "?$select=[COLUMN]&$top=3&$expand=[NAVIGATION COLUMN]($select=[COLUMN],[COLUMN])", 3)

Asynchronous function to wait on the return

When using retrieveMultipleRecords you might need to use an asynchronous function. The function needs to wait on retrieveMultipleRecords to return the values before continuing with the function. You do this by making two async functions, one with the main logic and the second one which retrieves the records.

async function xseption(formContext) {
    var xseptions = await getXseptions(companyProfileId);
    //Do something with the return
async function getXseptions(guid) {
    var query = "?$select=rc_categorytypeid,rc_xseptionsid&$filter=_rc_related_companyprofile_value eq " + guid + "&$expand=rc_categorytypeid($select=rc_value)";
    var result = await Xrm.WebApi.retrieveMultipleRecords("rc_xseptions", query);

    return result;

Embed a canvas app in a model-driven app

Did you know that you can embed (add) a canvas app in a model-driven app? With the embedded canvas app, you can fully use the power of the canvas app inside a model-driven app. In my project I used it to provide the user with the capability to search an Oracle database and select a specific company.

It is very easy to add a canvas app, but I recommend to use it only when no other options are viable. The reason for this is that the embedded canvas app needs to be reconnected every time you transfer the solution form one environment to another.

Embed the canvas app

  • Create / add a canvas app in the same environment as the model-driven app.
  • Open the form of the entity where the canvas app needs to be embedded.
  • Click on +Component and select the Canvas app.
  • Fill in the App ID Static value with the unique ID of the canvas app and click on Done.
  • You can find the App ID by right clicking on an app and clicking on Details.

Solution deployments

The canvas app is now part of the model-driven app and needs to be in the same solution. When you transfer the solution from the development environment to the test environment, you will need to update the model-driven form manually. The reason for this is that the model-driven app is still connected to the canvas app on development. You will need to change the reference / GUID to the canvass app on production. And do not forget to share the canvas app with the users.

Power Automate: Advanced Flow building

Power Automate is one of my favorite tools from the Power Platform. It is extremely versatile and can be used to automate tasks between online services and automate processes ranging from simple to highly complex. In this post, I will share with you 3 advanced expressions I have used recently on my project. One part of the project is to convert XML data to data we can store in the dataverse.

Convert XML to JSON for easy access

For a project I needed to read multiple XML files with millions of rows and store data from the files into the dataverse. XML is harder to use in a Flow then JSON, so with a simple expression I transformed the XML to JSON.

  • Add a compose action with the name XML to JSON with the following code.
  • Change the variable(‘XML’) to your XML content or store your XML content in that variable.
  • Add a parse json action set the Content to the output of the XML to JSON compose.
  • Add/create the JSON schema.

Using path in JSON

In most cases when you need to save data from JSON you can use the dynamic content to find it.
But sometimes you are looking for a field name that is not unique. In my case I needed a field called country related to the company. But the country field was used multiple times for various blocks. You can select the correct country by using the path (location) of the field in an expression.

  • Select the JSON through the dynamic content.
  • Copy the code from the dynamic content to the Expression.
  • Add the path add the end of the code.
  • I added to select the country of the company.

Dataverse lookup field

Lookup fields in Dataverse are really useful, but when you select them through the dynamic content the value will be the id not the display value. If the data must be readable for users, you can use the following steps to select the display value.

  • Add a compose to the flow.
  • Select the lookup field in the Inputs through the dynamic content.
  • Copy the code from the dynamic content to the Expression.
  • Your output looks something like this.
  • Add the @OData.Community.Display.V1.FormattedValue’ after rc_countrycode (your field name will be different).
  • The end results looks like this.

Power Automate: Find the current environment

When working with an ATOP setup you might need to know in which environment the Power Automate flow is running. For my solution I needed to know the environment because each environment uses a different Gateway and database credentials. In this post, I will share with you how to find the environment GUID and name.

Creating the flow

  • Create a flow and use the trigger Manually trigger a flow.
  • Add the action Get Environments under Power Apps for Makers
  • Add the Compose action and use the Workflow() expression, to get the current instance of the flow.
  • Parse the Output in a Parse JSON action.
  • Initialize a variable with the name environment as a string.
  • The Value is the EnvironmentName form the Parse JSON output.
  • Now you have the GUID of the current Environment in the variable.
  • To find the name of the current environment we need to go through the results of the Get Environments action.
  • Add a Condition control action and check if the environment variable is equal to the name from the Get Environments actions.
  • This will automatically add an Apply to each, this is because the Get Environments action might return more than one environment.
  • Add a Set variable action in the If yes section and set the variable environment to displayName.
  • Now you have the Name of the current Environment in the variable.
  • The final step is to add a Switch control and switch based on the name of the current environment.
  • The flow will now look like this.
