Below is a structured explanation of **Request Body options in Advanced REST Client (ARC)** and when each should be used:

* * *

### 1. None

Select this when the API does not require a request body.  
Typically used with GET requests or APIs where parameters are passed only in headers or query parameters.

* * *

### 2. Raw

Used when sending structured content such as Text, HTML, XML, or JSON.

- You can directly write the payload.

- Fields can be inserted using navigator (double-click).

- Template placeholders supported:

- When substituting string values, ensure they are enclosed in double quotes (“”).

Common use case: JSON payload for POST/PUT APIs.

* * *

### 3. form-data

Used to send multipart/form-data.

Recommended when:

- Uploading files

- Sending non-ASCII text

- Sending large binary data along with parameters

Configuration columns:

- Key Type (Text/File)

- Key

- Value

- Value Field

- Description

* * *

### 4. x-www-form-urlencoded

Used to send simple ASCII key-value pairs.

Commonly used for:

- Login APIs

- Token generation APIs

- Simple form submissions

Configuration columns:

- Key

- Value

- Description

* * *

### 5. Read from File

Used when the entire request body needs to be read from a file.

Configuration:

- Content-Type for request body

- File Path

- Option to view file content

Useful for:

- Large JSON/XML payloads

- Static request templates stored externally

* * *

### 6. Read from Field

Used when the request body is dynamically stored in a field during runtime.

Configuration:

- Content-Type

- Field Name (contains raw request body text)

Recommended when payload is generated earlier in the process.

* * *

### 7. Binary

Used when sending raw binary content directly from a file.

Typical use case:

- PDF, image, ZIP upload where API expects binary stream

* * *

### 8. GraphQL (Beta)

Used when interacting with GraphQL APIs.

You must specify:

- GraphQL Query (query or mutation)

- GraphQL Variables (optional dictionary for dynamic values)

Fields can be inserted using navigator or template placeholders.  
Ensure string substitutions are enclosed in double quotes.

Limitation: Subscription queries are not supported in ARC GraphQL
