# REST API Node

> Make HTTP requests to REST APIs with OpenAPI specification support

## Overview

The REST API Node allows you to make HTTP requests to any REST API endpoint. This node enables you to:

* Make GET, POST, PUT, DELETE, and other HTTP requests
* Configure headers and request bodies
* Import API configurations from OpenAPI specifications
* Use dynamic values from workflow inputs
* Handle JSON and other content types
* Integrate with external services and APIs

## Configuration Parameters

### Node Configuration

* **REST API Configuration**:

  Configure your API request using:

  * **Endpoint URL**: The target API endpoint (supports format strings)
  * **HTTP Method**: GET, POST, PUT, DELETE, PATCH, etc.
  * **Headers**: Key-value pairs for request headers
  * **Request Body**: Data to send (for POST/PUT/PATCH requests)
  * **Content Type**: Format of request body (JSON, form data, etc.)

  You can also import configuration from an OpenAPI specification URL for automatic setup.

## Expected Inputs and Outputs

* **Inputs**:

  * The node accepts text input that can be referenced in URLs, headers, and request bodies using format strings

* **Outputs**:

  * **output**: The response body from the API (typically JSON)

## Use Case Examples

1. **Third-Party Integration**:

   Call external APIs to send data, retrieve information, or trigger actions in other systems.

2. **Webhook Notifications**:

   Send webhook notifications to external services when workflow events occur.

3. **Data Fetching**:

   Retrieve data from REST APIs for processing in your workflow, such as fetching prices, weather data, or user information.

## Error Handling and Troubleshooting

* **Connection Errors**:

  Verify the endpoint URL is correct and the API is accessible from Pathlit's servers.

* **Authentication Issues**:

  Include necessary authentication headers (API keys, bearer tokens) in the headers configuration.

* **Response Parsing**:

  Ensure the API returns valid JSON if you're processing the response in downstream nodes.
