Sellsy proxy

Basic Sellsy API proxy; add CORS for full client side apps.

Server is deployed with consumer oauth keys and client must give its sellsy oauth token in each request.

Usage

Start the server with all the consumer API keys as environment variables

set CONSUMER_KEY="xxx";
set CONSUMER_SECRET="xxx";
npm start

Call Sellsy API from your browser

There are two ways to query the sellsy API :

Default : "transparent" proxy

Replace the default sellsy API endpoint with your proxy URL and it will relay all calls.

Also works with node-sellsy endPoint parameter.

via /GET

Using GET method, pass method and params url query parameters, following Sellsy API docs.

params must be URL encoded.

Also add oauth headers for the proxy :

// call to the API
const makeProxyRequest = ({ endPoint, method, params }) => {
  // create the proxy URL
  var urlParams = encodeURIComponent(params);
  // build url for the proxy
  var url = `${endPoint}?method=${method}&params=${urlParams}`;
  // use native fetch API and convert to JSON
  var request = new Request(url, {
    headers: new Headers({
      'X-USER-TOKEN': 'aaa',
      'X-USER-SECRET': 'bbb',
    }),
    mode: 'cors'
  });
  return fetch(request).then(r => r.json()).catch(e => {
    console.log('e', e);
    throw e;
  });
};

makeProxyRequest({
  endPoint: 'http://127.0.0.1:8282',
  method: 'Document.getList',
  params: JSON.stringify({
    doctype: 'invoice',
    search: {
      contains: 'test',
    },
  }),
}).then(data => {
  console.log(data);
});

You'll get the raw result from the Sellsy API.
