Configuration

Edit the .env file to configure your client ID, client secret and redirect URL, etc.

$ cp .env.sample .env
$ vi .env

Please visit Developer Portal to apply client ID and secret. And ensure the redirect URI in your config file has been entered in your app settings. By default, the URL is set to the following for this demo:

http://localhost:8080/callback

In the node.js entry file, create RingCentral SDK instance with parameters from the configuration file.

RingCentral platform accepts fax data in the form of multipart/form-data. In node.js, we use a module form-data to create multipart/form-data conveniently. This is our fax data holder.

Fax meta data is a json object where we can specify receivers, fax resolution and other properties of fax. After creating the meta data, append it to the formData.

RingCentral custom fax cover page can be rendered from HTML. Create an HTML page by Handlebars template engine. Append the HTML to the formData and set the contentType as text/html.

RingCentral custom fax cover page can be also rendered from PDF and multiple custom cover pages are accepted. Read the PDF file with node.js file stream and append it to the formData and set the contentType as application/pdf. Now the fax data is ready.

Log into RingCentral with password authentication flow.

After login, make POST request to RingCentral platform fax endpoint /account/~/extension/~/fax along with formData to send the fax.
