easy

Complete the code to create a Logic App trigger that starts when an HTTP request is received.

Azure

{

      }
    }
  }

💡 Hint

Common Mistakes

Using 'HttpTrigger' which is from Azure Functions, not Logic Apps.

Using 'Http' which is the 'kind' property, not the type.

Using 'HttpRequest' which is not a valid trigger type.

The trigger type for starting a Logic App on an HTTP request is Request.

Complete the code to add an action that sends an email using Office 365 connector.

Azure

{
  "actions": {
    "send_email": {
      "type": "[1]",
      "inputs": {
        "host": {
          "connectionName": "office365",
          "operationId": "SendEmail"
        },
        "parameters": {
          "To": "[e-mail]",
          "Subject": "Hello",
          "Body": "Welcome to Logic Apps!"
        }
      }
    }
  }
}

💡 Hint

Common Mistakes

Using 'Http' which is for HTTP calls, not connectors.

Using 'SendEmail' which is an operation, not a type.

Using 'Email' which is not a valid action type.

The action type to call a connector like Office 365 is ApiConnection.

hard

Fix the error in the condition expression to check if the variable 'count' is greater than 5.

Azure

{
  "actions": {
    "check_count": {
      "type": "If",
      "expression": "@greater([1], 5)",
      "actions": {}
    }
  }
}

Avariables('count')

Bcount

Cvariables[count]

Dvariables.get('count')

Attempts:

💡 Hint

Common Mistakes

Using 'count' directly which is undefined.

Using bracket notation which is invalid in Logic Apps expressions.

Using 'variables.get' which is not supported.

To access a variable in Logic Apps expressions, use variables('count').

4fill in blank

hard

Fill both blanks to create a loop that iterates over an array variable 'items' and appends each item to a string variable 'result'.

Azure

{
  "actions": {
    "for_each": {
      "type": "Foreach",
      "inputs": {
        "items": [1]
      },
      "actions": {
        "append_string": {
          "type": "AppendToStringVariable",
          "inputs": {
            "name": "result",
            "value": [2]
          }
        }
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

Avariables('items')

Bitems()

Citem()

Dvariables('result')

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'items()' which is not a variable or function here.

Using 'variables('result')' as the value to append instead of current item.

Using 'variables('items')' incorrectly inside the loop for current item.

The loop iterates over variables('items'). Inside the loop, item() gets the current element.

5fill in blank

hard

Fill all three blanks to define a Logic App action that initializes a variable named 'count' with integer type and value 0.

Azure

{
  "actions": {
    "init_count": {
      "type": "InitializeVariable",
      "inputs": {
        "variables": [
          {
            "name": [1],
            "type": [2],
            "value": [3]
          }
        ]
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

A"count"

B"integer"

C0

D"int"

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'int' instead of 'integer' for type.

Not quoting the variable name and type.

Using a string '0' instead of number 0 for value.

The variable name is "count", type is "integer", and initial value is 0.
