Request body

Use Body → Format on an HTTP request that sends a payload. Choose the format the endpoint expects, then check Headers for any content type required by that endpoint.

Choose a format

Format	What to enter
JSON	A JSON value, such as an object for a create request.
XML	An XML document.
Raw text	Plain text or a custom text format.
Form data	Multipart fields, each with a name and a text or file value.
Binary file	A single local file sent as the request body.

Try a JSON body

Start the Catalog API. Open an HTTP request with method POST and address http://127.0.0.1:8787/products.

Select Body → Format → JSON and paste the following payload.

{
  "name": "Travel Pouch",
  "category": "travel",
  "price": 24
}

Select Send. The test API returns 201 Created with the fields you sent, id: "p-demo", and inStock: true.

Use the format action to reindent JSON or XML. Use the search icon in the body editor to jump to text in a long payload.

Attach a file

For an endpoint that expects a multipart upload, select Form data, add the named field from the API documentation, and choose Make it a file field. For an endpoint that expects the file bytes as the whole payload, select Binary file, then Choose a file.

Follow Upload a file with form data to send a file alongside a text field and verify the response.
