So let’s see an example where we will create a flow that will send a successfully submitted email to the employee when an employee submits for the expense reimbursement in SharePoint Online List.

So, for this, we will create a two flow,

2. Child Flow: This flow contains the small tasks we want to run on parent flow.

Steps for how to call MS flow from another flow

Here we will see the steps on how to call MS flow from another flow.

Step 1 Create a SharePoint Online List

I have already created a SharePoint list called Expense Reimbursement, which had 4 columns with column types.

Column	Column Type
Title	Single line of text
Amount	Number
Date	Date and Time
Category	Choice

Apart from this column, you can add an in-built column that is hidden these are Attachments, and Created By.

Once your flow is ready we will create a child Flow First then we will create a parent flow in Power Automate.

Step 2: Create a child flow

To create a child flow, Log in to Power Automate. Then click on Solutions, click on New solution. Then Provide a Display Name, select a publisher from the drop-down and click on Create.

Then open that solution, and click on New -> Automation -> Cloud Flow -> Instant.

Next, provide the Flow name, and select the trigger ‘When an HTTP request is received, then click on Create.

Step 3: When an HTTP request is received

In this step provide the below JSON schema or else generate your sample JSON schema. Next click on Show advanced options and choose Method type as POST.

{
    "type": "object",
    "properties": {
        "Title": {
            "type": "string"
        },
        "Amount": {
            "type": "number"
        },
        "Date": {
            "type": "string"
        },
        "Category": {
            "type": "string"
        },
        "Created By": {
            "type": "string"
        },
        "Attachment": {
            "type": "string"
        },
        "Created By Email": {
            "type": "string"
        }
    }
}

Step 4: Send an Email

To send an email, click on the Next step and select Send an Email(V2) action. Then provide To, subject, and body field from the dynamic contentment which we get from the previous step.

Step 5: HTTP response

In this step, we will use response action, which is an incoming API call, and it used the result of an action to trigger this flow.

So, click on the Next step and select the Response action, then provide the status code as 200, and in the body write some message.

Now the child flow is ready to go, let’s create a parent flow and call the child flow.

Step 7: When an item is created

In this step provide the site address and list name of the SharePoint list.

Step 8: Run a child Flow

Now we will call the child flow inside the Parent flow, so click on the Next step and then select Run a child flow action. Then provide the child flow you have created, and provide the input to the child flow field.

Now our parent and child flow is ready, so now we can test the flow.

Step 9: Run the flow

Now to run the flow manually, click on Save and create an item in the list to trigger the flow.

Now in the below screenshot, you can see both the flows ran successfully.
