# Authentication

> One simple token that works everywhere

## Create a token

Visit [developer settings](https://dash.tessie.com/settings/api) and select *Generate Access Token*.

## Use your token

### In a header

The recommended and most secure method is to pass your token in a header:

`Authorization: Bearer YOUR_TOKEN`

### In the URL

For easy debugging and specific applications, it can be helpful to pass your token as the access\_token query parameter instead.

<Warning>
  Do not pass your access token in the URL on insecure networks or behind VPNs where traffic logs could potentially be snooped.
</Warning>

## Examples

You can use all APIs using a single Tessie access token:

### Tesla Fleet API

`https://api.tessie.com/api/1/vehicles?access_token=YOUR_TOKEN`

### Tesla Fleet Telemetry

`wss://streaming.tessie.com/YOUR_VIN?access_token=YOUR_TOKEN`

### Tessie API

`https://api.tessie.com/vehicles?access_token=YOUR_TOKEN`
