Creating a Logic App that showcases the use of all variable types

Trigger:

• Use a HTTP Request trigger to run the workflow manually.

2. Initialize Variables:

• Add an Initialize variable action for each variable type:
  • String Variable:
    • Name: myString
    • Type: String
    • Value: "Hello,"
  • Integer Variable:
    • Name: myInteger
    • Type: Integer
    • Value: 10
  • Boolean Variable:
    • Name: myBoolean
    • Type: Boolean
    • Value: true
  • Array Variable:
    • Name: myArray
    • Type: Array
    • Value: ["Apple", "Banana", "Cherry"]
  • Object Variable:
    • Name: myObject
    • Type: Object
    • Value: { "name": "John", "age": 30, "isActive": true }
  • Float Variable:
    • Name: myFloat
    • Type: Float
    • Value: 12.34

3. Manipulate Variables:

• Append to String:
  • Use the Append to string variable action to append text to myString:
    • Name: myString
    • Value: "World!"
• Increment Integer:
  • Use the Increment variable action to increment myInteger:
    • Name: myInteger
    • Value: 5
• Toggle Boolean:
  • Use the Set variable action to toggle myBoolean:
    • Name: myBoolean
    • Value: false
• Add to Array:
  • Use the Append to array variable action to add an item to myArray:
    • Name: myArray
    • Value: "Date"
• Update Object:
  • • Use the Compose action to update myObject:
      • Inputs: @json(concat('{ "name": "', variables('myObject')?['name'], '", "age": ', add(variables('myObject')?['age'], 1), ',}'))
• Decrement Integer:
  • Use the Decrement variable action to decrement myFloat:
    • Name: myFloat
    • Value: 2.12

4. Output Variables:

• Use the Response action to return the final values of all variables:
  • Status Code: 200
  • Body:
    

    {
      "myString": "@{variables('myString')}",
      "myInteger": "@{variables('myInteger')}",
      "myBoolean": "@{variables('myBoolean')}",
      "myArray": "@{variables('myArray')}",
      "myObject": "@{variables('myObject')}"
      "myFloat": "@{variables('myFloat')}"
    }
