    # Introduction

    This is reference documentation for the Next Matter API. It is a RESTful API
    that can be interacted with by sending JSON-formatted requests. Responses
    are also returned in a JSON format.

            The API doesn't expose any endpoints of the workflow editor.
            This means you can't use this API to edit the underlying workflow structure or change definitions.
     # Testing a request

            Use a third party client, such as curl, Postman, or Advanced REST Client, to test our REST API.

        Authentication is API key based. As an admin, you can generate an API
        key in Next Matter by going to Company > Next Matter API keys.


        When sending requests to the API, authenticate by passing the API key in
        the "Authorization"

        HTTP header, prepended with the string "Api-Key ".


        For example:

         Authorization: Api-Key xyzabc.12fsfe242ubdgakew
      name: Authorization
      in: header
      x-default: Api-Key YOUR_NM_API_KEY
