Configure Power Automate cloud flows in Power Pages

  • Grein

Power Automate cloud flow allows users to create automated workflows between different applications and services. You can use a Power Automate cloud flow to create logic that performs one or more tasks when an event occurs. For example, configure a button so that when a user selects it, send an email or meeting request, update a record, collect data, synchronize files, and other tasks.

Now, you can securely invoke Power Automate cloud flows from Power Pages to interact with 1000+ external data sources and integrate it into your business site.

Note

  • Your Power Pages site version must be 9.5.4.xx or later for this feature to work.
  • Your starter site package version must be 9.3.2304.x or higher.

Prerequisites

To integrate with Power Pages, a Power Automate license is required. It's recommended to use a Power Automate Process license in the production instance.

Steps to integrate cloud flow

  1. Create a cloud flow.

  2. Add the flow to your site.

  3. Invoke a flow from your website.

  1. Sign into Power Pages.

  2. Select site + Edit.

  3. Navigate to the Set up workspace, then select Cloud flows under App integrations.

  4. Select + Create new flow.

    Selecting Power Pages options in Power Automate.

  6. Define your flow steps and return values and select Save.

Note

Only solution-aware flows can be attached to the Power Pages site.

After you create an instant cloud flow, it needs to be associated with the Power Pages site and secured with a web role.

  1. Sign into Power Pages.

  2. Select site + Edit.

  3. Navigate to the Set up workspace, then select Cloud flows (preview) under App integrations.

  4. Select + Add cloud flow.

  6. Select + Add roles under Roles.

  7. Select roles that should have access to the flow.

  8. Select Save.

    Add cloud flow to website.

Note

When you add a flow to your site, a unique URL is generated that allows you to invoke the cloud from your site.

Invoke a flow from web page

Use Power Pages cloud flow API to interact with Power Automate to perform external service integration. Cloud flow API operations consist of HTTP requests and responses.

Operation Method URI
Invoke cloud flow POST [Site URI]_/api/cloudflow/v1.0/trigger/<guid>

Example:

Request

POST https://contoso.powerappsportals.com/_api/cloudflow/v1.0/trigger/4d22a1a2-8a67-e681-9985-3f36acfb8ed4
{
    "Location":"Seattle"
}

Response

Cloud flow without response action

HTTP/1.1 Accepted
Content-Type: application/json

Cloud flow with response action

HTTP/1.1 200 OK
Content-Type: application/json
Body
{
    "conditions":"Rain",
    "humidity":"93",
    "latitude":"47.60620880126953",
    "longitude":"-122.33206939697266"
}

Authenticating cloud flow API requests

You don't need to include an authentication code, because the application session manages authentication and authorization. All API calls must include a Cross-Site Request Forgery (CSRF) token.

Passing parameter to cloud flow

In a cloud flow, you can define input parameters of type Text, Boolean, File, and Number. The parameter name you define in the request body should match the parameter name defined in the cloud flow trigger.

Important

  • You must pass the request parameters name as defined in the cloud flow.
  • Support for passing a parameter to a flow configured with secure inputs is not available.

Sample JavaScript to call a flow

This sample demonstrates how to call a flow using Asynchronous JavaScript and XML (AJAX).

    shell.ajaxSafePost({
        type: "POST",
        url: "/_api/cloudflow/v1.0/trigger/44a4b2f2-0d1a-4820-bf93-9376278d49c4",
        data: {"eventData":JSON.stringify({"Email": "abc@contoso.com", "File":{"name":"Report.pdf", "contentBytes":"base 64 encoded string"} })}
    })
    .done(function (response) {
    
    })
    .fail(function(){
    
    });
