Body Editor

The Body tab lets you configure the request payload. The available editor depends on the body type.

Body Types

Type	Editor	Use Case
None	—	GET, HEAD, DELETE requests
JSON	Monaco Editor (syntax-highlighted)	REST APIs, GraphQL
XML	Monaco Editor (syntax-highlighted)	SOAP, legacy XML APIs
Text	Plain text area	Raw text payloads
Form Data	Key-value editor	File uploads, multipart forms
URL Encoded	Key-value editor	Standard web forms

JSON Editor

The JSON editor is powered by Monaco Editor (the same engine as VS Code). Features:

• Syntax highlighting
• JSON validation
• Format button (pretty-print JSON)

// Select Body type: JSON
// Enter:
{
  "name": "John Doe",
  "email": "john@example.com",
  "age": 30
}
// Click Format to beautify

Form Data

Use the key-value editor to build multipart form data. Each entry has a key and value.

// Body type: Form Data
//   username = johndoe
//   avatar   = (binary file selection)

URL Encoded

Standard application/x-www-form-urlencoded format.

// Body type: URL Encoded
//   grant_type = authorization_code
//   code       = abc123
//   redirect_uri = https://example.com/callback

Environment Variables

Use {{variable_name}} in any body field. Flamingo resolves variables before sending.
