Interacting with Power Automate from World of Workflows

Summary

This guide provides a step-by-step tutorial on integrating an World of workflow with Power Automate. The workflow demonstrates how to trigger a Power Automate flow and wait for its completion using HTTP callbacks.

Step-by-Step Guide

Setting Up Power Automate

1. Create a New Flow:
   • Start by creating a new flow in Power Automate.
   • Use the “When an HTTP request is received” trigger to begin the flow.
2. Configure the HTTP Request:

   • Define the JSON schema that will be sent from World of Workflows, such as

      {
         "type": "object",
         "properties": {
            "RunCode": {
                  "type": "string"
            }
         }
      }
     

3. Add Your Logic:
   • Implement any necessary logic within Power Automate.
   • For example, add conditions or other actions depending on your needs.
4. HTTP GET Callback:
   • At the end of the Power Automate flow, add an HTTP action to make a GET request back to the World of workflow’s /powerautomate/complete endpoint.
5. Save and Publish the Flow:
   • Save the flow and copy the HTTP POST URL provided by Power Automate. This URL will be used in your workflow.

Setting Up the Workflow

Follow these steps to set up your workflow to interact with Power Automate:

1. Define the Power Automate API Endpoint

• Activity: SetVariable
• Variable Name: powerAutomateAPI
• Value: The Power Automate HTTP POST URL.

{
  "VariableName": "powerAutomateAPI",
  "Value": "As provided by Power Automate"
}

2. Set the HTTP Request Content

• Activity: SetVariable
• Variable Name: httpContent
• Value: JSON content to pass through to the Power Automate flow.

{
    "RunCode": "StartPowerAutomate"
}

3. Send HTTP Request to Start Power Automate

• Activity: SendHttpRequest
• URL: getVariable("powerAutomateAPI")
• Method: POST
• Content: getVariable("httpContent")

4. Wait for Power Automate to Complete

• Activity: HttpEndpoint
• Path: /powerautomate/complete
• Method: GET

This activity initializes the follow-up segment of the workflow.

5. Clean Up Workflow Instances

• Activity: RemoveWorkflowInstances
• Workflow Definition Name: PowerAutomateWorkflow
• Version Selection: All
• Instance Retention: 1

Workflow: Power-Automate-Workflow
