What Is the N8n HTTP Request Node?

The N8n HTTP Request Node is a flexible tool used to send HTTP/HTTPS requests within an n8n workflow. It allows you to interact with REST APIs, webhooks, and external servers using any standard HTTP method including GET, POST, PUT, PATCH, and DELETE.

With this node, you can:

Fetch data from APIs
Send form data or JSON payloads
Upload files
Trigger external microservices
Integrate cloud apps without native n8n nodes
Chain multiple API calls for complex sequences

Because almost every modern service exposes an API, the N8n HTTP Request Node acts as a universal connector in your workflow automation system.

Why the N8n HTTP Request Node Is Essential

While n8n offers hundreds of prebuilt nodes, not every tool or platform has native support. The HTTP Request Node eliminates limitations by letting you connect to any API, even those without official integrations.

Key Benefits

Unlimited Integrations – If it has an API, you can use it with this node.
Flexible Data Handling – Send and receive most formats: JSON, XML, text, binary, and more.
Customizable – Headers, query parameters, authentication, and advanced config are all possible.
Scalable – Handle small requests or large automation workflows effortlessly.
Supports Secure Authentication – OAuth2, API keys, headers, bearer tokens, and custom auth flows.

How to Use the N8n HTTP Request Node (Step-by-Step)

1. Add the Node to Your Workflow

From the left sidebar in the n8n editor, search for “HTTP Request” and drag it into your workflow editor. Connect it to any previous node or use it as the starting point.

2. Select Your HTTP Method

Choose the type of request you need:

GET – Retrieve data
POST – Create resources or submit data
PUT – Update existing resources
PATCH – Partially update resources
DELETE – Remove a resource

Most APIs use JSON-based POST or GET requests, but the method depends on the API documentation of the service you're calling.

3. Enter the API Endpoint URL

Paste the full URL of the API endpoint. Example:

https://api.example.com/v1/users

You may also dynamically insert variables using expressions:

{{ $json.userId }}

Configuring Parameters in the HTTP Request Node

The most common configuration options include query parameters, body data, and headers. Let’s explore them.

Query Parameters

Query params are appended to your URL. Example:

?page=1&limit=10

In n8n, add them under:

HTTP Request Node → Parameters → Query Parameters

Headers

Headers define request metadata such as content types and authentication tokens. Common examples:

Content-Type: application/json
Authorization: Bearer YOUR_TOKEN
Accept: application/json

You can add as many headers as needed, depending on the API provider’s requirements.

Body Parameters

The node supports multiple request body formats:

JSON
Form-data
URL-encoded
Binary file uploads

For JSON payloads, select “JSON” as the Body Content Type and enter your fields.

Authentication Options in the N8n HTTP Request Node

Most APIs require authentication. The HTTP Request Node includes several built-in methods.

API Key Authentication

This is the simplest method. Your key may go in:

Headers
Query parameters
Request body

Bearer Token

Add:

Authorization: Bearer YOUR_TOKEN

Basic Auth

Enter your username and password in the dedicated Basic Auth fields.

OAuth2

OAuth2 setup requires:

Client ID
Client Secret
Token URL
Authorization URL
Scopes

Once configured, n8n automatically refreshes tokens.

Handling Responses in the HTTP Request Node

API responses can be returned as:

JSON
Text
Binary

Parsing JSON Responses

Most APIs respond with JSON. The node automatically parses JSON into an object you can access in later nodes.

Example output:

{
  "id": 42,
  "name": "John Doe",
  "email": "john@example.com"
}

You can access this data using expressions like:

{{ $json.email }}

Error Handling

Common error types include:

400 – Bad Request (invalid input)
401 – Unauthorized
403 – Forbidden
404 – Resource not found
500 – Server error

You can enable "Continue On Fail" to stop your workflow from breaking on errors.

Advanced Features of the HTTP Request Node

Binary Data Handling

You can upload files or handle binary downloads such as:

PDF
CSV
Images

Binary mode is useful for file processing workflows, backups, or cloud storage integrations.

Rate Limiting Support

Some APIs require rate control. You can combine the HTTP Request Node with:

Wait nodes
Function nodes
Batch processing nodes

Dynamic URL and Parameter Generation

Using expressions, you can create dynamic URLs:

https://api.example.com/user/{{ $json.userId }}

Best Practices for Using the N8n HTTP Request Node

1. Use Environment Variables

Avoid hardcoding API keys. Store them in environment variables for security.

2. Validate API Responses

Use IF nodes to check for missing fields or unexpected values.

3. Use Pagination for Large Datasets

Loop through pages using a combination of Set, IF, and HTTP Request nodes.

4. Log Important Responses

Send logs to a database or sheet for debugging and audit purposes.

5. Minimize API Calls

Cache results where possible to reduce load and save time.
