Access the Guild Wars 2 API

The Guild Wars 2 API supports JWT tokens, called subtokens by the API, in addition to the usual API key to authorize requests. You can request a subtoken from the gw2.me API so you can make authorized requests to the Guild Wars 2 API yourself.

Subtokens generated by gw2.me are only valid for a short time (usually 10 minutes). This is because subtokens can not be invalidated and should stop working shortly after the user removes the authorization for your app.

Get Accounts

Before you can request a subtoken, you will need to get the list of accounts the user has shared with your application. Make a request to https://gw2.me/api/accounts. You will need to pass your access_token as a header (Authorization: Bearer <access_token>). This requires the accounts scope.

The response will be a JSON object with the list of accounts with the account id and name as returned by the /v2/accounts Guild Wars 2 API endpoint.

{
  "accounts": [
    {
      "id": "C2BFF77D-B669-E111-809D-78E7D1936EF0",
      "name": "darthmaim.6017"
    }
  ]
}

If the scopes include accounts.displayName, each account object will include the displayName the user has set (or null, if the user has not set a custom display name). Similarly, if the scope accounts.verified is included, the response will contain the boolean verified with the ownership verification status of each account.

Request Subtoken

Now you can request a subtoken for an account. Make a request to https://gw2.me/api/accounts/<accountId>/subtoken, again including the Authorization: Bearer <access_token> header. You can optionally include the permissions query parameter with comma-separated permissions to request a specific subset of permissions.

The response will include the generated subtoken and the expiration timestamp of that subtoken.

{
  "subtoken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJpU0V6M3NBOC1PejdteUUtVTEwbW53dWM2ZlFxMzh3dm5TRU45SVlnMGdZIiwiaWF0IjoxNjk4OTI3MTA4LCJleHAiOjE2OTg5Mjc3MDgsInBlcm1pc3Npb25zIjpbImFjY291bnQiXX0.YZRAmJ8o-T6c0r4IHspy3S2Nqz7zEBtc22b36xzbL6g",
  "expiresAt": "2023-11-02T12:21:48.000Z"
}

It is currently not possible to request multiple subtokens in bulk with one request.
