## VRM API

### Introduction

This document provides a brief overview of some of the available endpoints and their parameters. The API is a REST API, accepting JSON as request body.

### Authentication

Most endpoints require authentication, using a JWT token. This token should be placed in the `x-authorization` field in the HTTP header. There are two types of tokens:

*   **Bearer token**: Uses the `Bearer <token_value>` format. This is used when logging in to VRM, for example. Can be retrieved from `/auth/login` or `/auth/loginAsDemo`.
*   **Access token**: Uses the `Token <token_value>` format. This is commonly used for third party applications using the VRM API. Can be created using `/users/{idUser}/accesstokens/create`.

### Rate Limiting

Most endpoints are by default rate limited with a rolling window of max 200 requests, where every 0.33 seconds a request gets removed from the rolling window (so on average maximum of 3 requests per second won't get rate limited). There are different types of rate limiting in VRM. If you receive a 429 with a JSON response, you can check the `Retry-After` response header to check the amount of seconds you have to wait until retrying.
