1. Please note that this package is a wrapper for an API, so it's logic runs on external servers.
2. Your data is secure and will not be shared with third parties.
3. We try to keep the API up and running at all times, but we cannot guarantee 100% uptime. Please build in a retry
mechanism in case the API is down for maintenance.
4. Make sure to upgrade your package to either >2.4.0 or >3.0.25 for apiKey support.

- Android: https://play.google.com/store/apps/details?id=nl.dashweb.factuursimpel
2. Create an API key through the app: settings -> API keys
3. Make sure to upgrade your package to either >2.4.0 or >3.0.25 for apiKey support.
4. Use the API Key as shown in the complete example below. Add the apiKey property to the data object.
Note: The GUI is not (yet) fully translated to English, though the path to getting an apiKey should mostly be in
English. Also this will allow you to use the in app purchase mechanism to pay for the subscription.
When using the free version, you can set the mode to 'development' to make sure you are not running into rate limits
while testing this package or developing your invoices. The free version is limited to 25 invoices per 15 days. When
your
invoice looks good, you can switch to 'production' mode to create your production invoices. Production mode is activated
by either not setting the mode or setting the mode to 'production'.
In case you don't want to use NPM, but you want to call our invoice creation api directly.

CommonJS
`js
var easyinvoice = require('easyinvoice');
`ES6 =<
`js
import easyinvoice from 'easyinvoice';
`Getting Started - Basic Example
NodeJS
`js
// Import the library into your project
var easyinvoice = require('easyinvoice');// Create your invoice! Easy!
var data = {
apiKey: "free", // Please register to receive a production apiKey: https://app.budgetinvoice.com/register
mode: "development", // Production or development, defaults to production

}
]
};
easyinvoice.createInvoice(data, function (result) {
// The response will contain a base64 encoded PDF file
console.log('PDF base64 string: ', result.pdf);
// Now this result can be used to save, download or render your invoice
// Please review the documentation below on how to do this
});

`High volume: asynchronous invoice creation
Our API is able to handle high volumes of requests. If you need to create a lot of invoices fast, make sure to create
them asynchronously. This will allow you to create multiple invoices at the same time.
Note: using async/await for this example
`js
// Import the library into your project
var easyinvoice = require('easyinvoice');// Create a promises array to store all your promises
const promises = [];
// Use a loop to prepare all your invoices for async creation
for (let i = 0; i < 25; i++) {
// Add your invoice data to the promise array
promises[i] = easyinvoice.createInvoice({
apiKey: "free", // Please register to receive a production apiKey: https://app.budgetinvoice.com/register
mode: "development", // Production or development, defaults to production
});
}
// Create all your invoices at the same time
const invoices = await Promise.all(promises);
