Refreshing

[IMgoRt]

Hi,
I have a valid refresh token, how would I subsequently execute your code using the refresh_token rather than starting from email/password?

Thanks

There's no built-in function for refreshing a token in the HTML page. But if you run it locally with node.js it's super easy making your own, just using the cleaned-up teslaAuth.js library I added in the latest commit.

Clone or download the repository. Then create a refresh.js file in the root (next to the teslaAuth.js file), just containing something like this.

const teslaAuth = require("./teslaAuth");

const token = teslaAuth
    .refreshToken("<<<YOUR REFRESH TOKEN>>>")
    .then(t => console.log(t))

Run it with node refresh.js

The refresh call is a simple POST to the Tesla server. You can just curl it if you like.

curl --header "Content-Type: application/json" --data '{
 "grant_type":"refresh_token",
 "scope":"openid email offline_access",
 "client_id":"ownerapi",
 "refresh_token":"<<<YOUR REFRESH TOKEN>>>"
}' https://auth.tesla.com/oauth2/v3/token

The teslaAuth.js file is all you need from my repository if you want to put the function in your own project. Just copy that single file and then you can use the authenticate, refreshToken, and ownerapiToken functions. They're all documented inside the source.

That's great, thanks for taking the time to reply, I'll try it out in the morning (01:11 here)
