How to Convert HTTP Requests to JSON in Make.com: A Step-by-Step Guide
Struggling with messy API responses that come as raw HTML? Learn how to automatically transform HTTP requests into clean, structured JSON data using Make.com's visual workflow builder - no coding required. This essential skill will supercharge your API integrations and automation projects.
Why Parse HTTP to JSON?
When working with APIs, you'll often receive responses in raw HTML format that's difficult to work with programmatically. JSON (JavaScript Object Notation) provides a structured alternative that's both human-readable and machine-friendly. Over 70% of modern APIs use JSON as their primary data format, making this parsing skill essential for automation.
Without proper parsing, API responses remain locked in a format that requires manual extraction or complex string manipulation. By converting to JSON, you unlock the ability to:
- Access specific data fields directly
- Transform and manipulate the data easily
- Integrate with other applications seamlessly
- Build more reliable and maintainable workflows
Key benefit: JSON parsing turns unstructured API responses into organized data you can actually use in your automations, saving hours of manual processing.
Getting Started with Make.com
Make.com (formerly Integromat) provides a visual interface for building automation workflows without coding. To begin parsing HTTP responses:
Step 1: Access Your Make.com Account
Navigate to Make.com and log in to your account. If you don't have one yet, you can start with a free plan that includes all the features needed for this tutorial.
Step 2: Create a New Scenario
Click the purple "Create a new scenario" button in the top right corner. Scenarios are Make.com's term for individual workflows or automation recipes.
Pro tip: Name your scenario descriptively (e.g., "Weather API to JSON Parser") to make it easier to identify later among your growing collection of automations.
Creating Your HTTP Request
The foundation of our JSON parsing workflow is the HTTP module, which lets you communicate with web APIs. Here's how to set it up:
Step 1: Add the HTTP Module
Click the big plus icon in the scenario editor and search for "HTTP". Select "Make a request" from the dropdown options.
Step 2: Configure the Request
In the module settings:
- Enter the API endpoint URL
- Set the method to GET (for retrieving data)
- Add any required headers or query parameters
Important: Double-check your API documentation for the correct endpoint structure and any required authentication parameters before testing.
Configuring Response Parsing
This is where the magic happens - converting raw HTTP responses to structured JSON:
Step 1: Enable Parsing
In the HTTP module settings, locate the "Parse response" option and set it to "Yes". This tells Make.com to automatically convert the response body to JSON.
Step 2: Handle the Output
Once parsed, the JSON data becomes available in Make.com's data structure. You can:
- Map specific fields to subsequent modules
- Transform the data using built-in functions
- Filter arrays based on conditions
Watch for: Some APIs return JSON by default while others need explicit parsing. Check the response headers for "Content-Type: application/json" to confirm.
Testing Your Workflow
Before putting your parser into production, thorough testing is essential:
Step 1: Run Once
Click the "Run once" button at the bottom left to execute your scenario manually. This sends your HTTP request and attempts to parse the response.
Step 2: Verify Output
Check the execution panel to ensure:
- The HTTP request succeeded (status code 200)
- The response was properly parsed to JSON
- All expected data fields are present
Troubleshooting tip: If parsing fails, examine the raw response to determine if the API is returning valid JSON or if you need additional preprocessing steps.
Common Use Cases
HTTP-to-JSON parsing unlocks numerous automation possibilities:
API Integrations
Connect SaaS platforms like CRM, marketing tools, or databases by parsing their API responses into usable data.
Data Aggregation
Combine information from multiple sources into unified reports or dashboards by standardizing on JSON format.
Webhook Processing
Parse incoming webhook payloads from services like Stripe or Shopify into structured data for your workflows.
Real-world example: A retail client used this technique to automatically update inventory levels by parsing responses from their eCommerce platform's API, saving 15 hours per week of manual work.
Troubleshooting Tips
When your JSON parsing isn't working as expected:
Check Response Headers
Ensure the API is actually returning JSON content (Content-Type: application/json). Some APIs require specific Accept headers.
Validate JSON Structure
Use a JSON validator to check if the response is properly formatted. Malformed JSON will fail to parse.
Handle Errors Gracefully
Add error handling routes in your scenario to manage cases where parsing fails or returns unexpected data.
Remember: The HTTP module's "Show advanced settings" reveals options for timeout configuration and other parameters that might help with problematic APIs.

Frequently Asked Questions
Common questions about this topic
Parsing HTTP responses to JSON is essential when working with APIs because JSON provides a structured, machine-readable format that's easier to work with than raw HTML. Most modern APIs return data in JSON format, which allows for easier data extraction, manipulation, and integration with other systems.
Without proper parsing, API responses would be difficult to process and use in your automations. JSON's hierarchical structure lets you access specific data elements directly rather than parsing through unstructured text.
- JSON is the standard format for API communication
- Structured data enables precise field access
- Simplifies integration between different systems
Make.com can parse responses from GET, POST, PUT, and DELETE HTTP requests into JSON format. The most common use case is parsing GET requests when retrieving data from APIs. The parsing functionality works regardless of the HTTP method used, as long as the server returns data in a format that can be converted to JSON.
The platform handles the response parsing automatically when you enable the "Parse response" option in the HTTP module settings. This works consistently across all HTTP methods supported by Make.com.
