Are you tired of manually extracting data from JSON files in your Azure Logic App? Do you want to simplify your workflow and make it more efficient? Look no further! In this article, we’ll show you how to create an Azure Logic App that initializes a variable after parsing a JSON action. Follow our step-by-step guide to unlock the full potential of your Logic App and take your workflow to the next level.
Prerequisites
Before we dive into the tutorial, make sure you have the following prerequisites:
- An Azure subscription
- A basic understanding of Azure Logic Apps
- A JSON file with data you want to extract
Step 1: Create a New Azure Logic App
To create a new Azure Logic App, follow these steps:
- Log in to your Azure portal
- Click on “Create a resource” and search for “Logic App”
- Click on “Logic App” and then click “Create”
- Choose a subscription, resource group, and location for your Logic App
- Give your Logic App a name and click “Create”
Step 2: Add a Trigger
In this step, we’ll add a trigger to our Logic App. A trigger is an event that sets our Logic App in motion. For this tutorial, we’ll use an HTTP trigger.
Follow these steps to add an HTTP trigger:
- In your Logic App, click on “New step”
- Search for “HTTP” and select “HTTP trigger”
- Choose “When an HTTP request is received” as the trigger type
- Click “Add” to add the trigger
Step 3: Add a Parse JSON Action
In this step, we’ll add a Parse JSON action to our Logic App. This action will parse the JSON data from our trigger and make it available for further processing.
Follow these steps to add a Parse JSON action:
- In your Logic App, click on “New step”
- Search for “Parse JSON” and select “Parse JSON”
- Select the “Body” of the HTTP request as the content to parse
- Click “Add” to add the action
Step 4: Initialize a Variable
In this step, we’ll initialize a variable using the data from our Parse JSON action. This variable will store the extracted data and make it available for further processing.
Follow these steps to initialize a variable:
- In your Logic App, click on “New step”
- Search for “Initialize variable” and select “Initialize variable”
- Give your variable a name and select “String” as the data type
- In the “Value” field, select the “dynamincontent” property from the Parse JSON action
- Click “Add” to add the action
{
"type": "string",
"value": "@body('Parse_JSON').dynamincontent"
}
Step 5: Test Your Logic App
In this final step, we’ll test our Logic App to ensure it’s working as expected.
Follow these steps to test your Logic App:
- In your Logic App, click on “Run”
- In the “Run” window, click on “Add input” and select the JSON file you want to test
- Click “Run” to execute the Logic App
- Check the “Variables” section to see the extracted data
| Variable Name | Value |
|---|---|
| dynamincontent | The extracted data from the JSON file |
Troubleshooting
If your Logic App is not working as expected, check the following common issues:
- Make sure the JSON file is in the correct format
- Verify that the Parse JSON action is correctly configured
- Check that the variable is correctly initialized and referenced
Conclusion
And that’s it! You’ve successfully created an Azure Logic App that initializes a variable after parsing a JSON action. With this tutorial, you’ve unlocked the power of Azure Logic Apps and taken your workflow to the next level. Remember to always test and troubleshoot your Logic Apps to ensure they’re working as expected.

FAQs
Q: What is Azure Logic Apps?
A: Azure Logic Apps is a cloud-based platform for automating workflows and integrating apps, services, and systems.
Q: What is a trigger in Azure Logic Apps?
A: A trigger is an event that sets an Azure Logic App in motion, such as an HTTP request or a scheduled task.
Q: What is a Parse JSON action?
A: A Parse JSON action is an action that parses JSON data from a trigger or previous action and makes it available for further processing.
Q: How do I initialize a variable in Azure Logic Apps?
A: You can initialize a variable by adding an “Initialize variable” action and selecting the data type and value for the variable.
Q: Can I use Azure Logic Apps for free?
A: Yes, Azure Logic Apps offers a free plan with limited features and executions. You can upgrade to a paid plan for more features and executions.

Frequently Asked Question
Get ready to unravel the mystery of creating Azure logic apps and initializing variables after parsing JSON actions!
How do I create a new variable in an Azure Logic App?
Easy peasy! To create a new variable, simply click on the “Variables” section in the Logic App designer, then click the “Add a variable” button. Give your variable a name, choose the data type, and set its initial value. You can also use the “Initialize variable” action in the workflow to create a new variable.
What is the purpose of the “Parse JSON” action in Azure Logic Apps?
The “Parse JSON” action is a game-changer! It allows you to extract data from a JSON object and make it available as separate variables in your Logic App. This action is especially useful when working with APIs or receiving JSON data from an external source.
How do I initialize a variable after parsing JSON in an Azure Logic App?
After adding the “Parse JSON” action, you can initialize a variable by clicking on the “Add an action” button and selecting “Initialize variable”. Then, you can use the dynamic content feature to access the parsed JSON data and set it as the initial value of your variable.
Can I use the “Set variable” action instead of “Initialize variable” in Azure Logic Apps?
While you can use the “Set variable” action to update an existing variable, it’s not the same as initializing a new variable. The “Initialize variable” action is specifically designed to create a new variable and set its initial value, whereas “Set variable” is used to update an existing variable.
What are some common use cases for initializing variables after parsing JSON in Azure Logic Apps?
Initializing variables after parsing JSON is useful in scenarios like processing API responses, handling JSON data from a messaging queue, or extracting data from a JSON file. By initializing variables, you can make the extracted data readily available for further processing and manipulation in your Logic App.
