Authorization

The OpenAPI generator supports Bearer Token authorization. In order to enable the sending of tokens in each request you can set the token using the global OpenAPI configuration:

import { OpenAPI } from './generated';

OpenAPI.TOKEN = 'some-bearer-token';

Alternatively, we also support an async method that provides the token for each request. You can simply assign this method to the same TOKEN property in the global OpenAPI object.

import { OpenAPI } from './generated';

const getToken = async () => {
    // Some code that requests a token...
    return 'SOME_TOKEN';
};

OpenAPI.TOKEN = getToken;
