File to variable

You can use the @file-to-variable directive to read the content of a file and assign it to a variable.

Create a file with the .http extension and write your JSON request in it.

Then, use the @file-to-variable directive to specify the variable name that you want to use in the request.

The second argument is the path to the file.

file-to-variable.http

POST https://httpbin.org/post HTTP/1.1
Content-Type: application/json
Accept: application/json
# @file-to-variable TEST_INCLUDE ./test-include.json

{
  "test-include": {{TEST_INCLUDE}}
}

The TEST_INCLUDE variable will be replaced with the content of the test-include.json file.

test-include.json

{
  "foo": "bar",
  "baz": {
    "qux": "quux"
  }
}
