OAuth 2 flow

You can request and refresh OAuth 2 tokens using this client. First of all, import the necessary module and instantiate the class with your client id and client secret:

const { LokaliseAuth } = require('@lokalise/node-api');

const lokaliseAuth = new LokaliseAuth("client id", "client secret");

Now lokaliseAuth can be used to request and refresh tokens.

Generating authentication URL

The next step is generating a special authentication URL:

const url = lokaliseAuth.auth(
  ["read_projects", "write_team_groups"],
  "http://example.com/redirect",
  "random123"
);

Your users must visit this URL and explicitly permit access. As a result, they'll get an authentication token that you'll require on the next step.

THe auth method accepts the following arguments:

  • scope (string or array of strings, required) — OAuth 2 scopes that you would like to request access to.
  • redirect_uri (string, optional)
  • state (string, optional) — a random string to protect from CSRF attacks.

Requesting OAuth 2 access token

Now request the token using the secret code obtained at the previous step:

const response = await lokaliseAuth.token("secret code");

The response is an object with the following keys:

  • access_token — your OAuth 2 access token.
  • refresh_token — token to request a new access token.
  • expires_in — token expiration time.
  • token_type — usually, "Bearer".

Refreshing OAuth 2 access token

OAuth 2 access token has an expiration date but you can easily obtain a new one using refresh token:

const response = await lokaliseAuth.refresh("refresh token");

The response is an object with the following keys:

  • access_token — your new access token.
  • scope — an array of OAuth 2 scopes that you requested initially.
  • expires_in — token expiration time.
  • token_type — usually, "Bearer".

Using OAuth 2 tokens

After you've obtained an OAuth 2 token, you can use it to perform requests on the user's behalf:

const { LokaliseApiOAuth } = require('@lokalise/node-api');

const lokaliseApi = new LokaliseApiOAuth({ apiKey: '<apiKeyObtainedViaOauth2>' });

const projects = lokaliseApi.projects().list();
