HTTP Call Block
Make HTTP requests to external APIs and services
Overview
The HTTP Call Block allows you to make HTTP requests to specified URLs with custom methods, headers, and body. This versatile block is essential for interacting with external APIs or services within your workflow.
Inputs
The HTTP method to use for the request (GET, POST, PUT, DELETE). Only shown when “Use Input” is enabled for Method.
The URL to make the HTTP request to. Only shown when “Use Input” is enabled for URL.
An object containing the headers to include in the HTTP request. Only shown when “Use Input” is enabled for Headers. Can accept a string containing JSON or an object.
The body of the HTTP request. Only shown when “Use Input” is enabled for Body. Can accept a string or an object that will be stringified.
Outputs
The raw text body of the HTTP response.
If the response has a content-type of application/json, this output will contain the parsed JSON object. Otherwise, this output will not be available.
The HTTP status code of the response.
An object containing the headers from the HTTP response.
Editor Settings

- Headers provided via input can be either a JSON string or an object
- Body content provided via input can be either a string or an object (which will be stringified)
- The JSON output is only available when the response has a content-type of application/json
