Quick Invoices Endpoint

Quick Invoices is a way for a merchant to send an email to a customer with a link to make a payment. This link, when clicked, opens a browser containing the Quick Invoice of whatever it is that the customer purchased. Each Quick Invoice email will have the ability to be customized by the merchant. There will be a default template provided for the merchant as a starting point. Once paid, the customer will receive an email thanking them for their payment. The system will send the customer email notifications prior to the due date, on the due date, and past the due at the discretion of the merchant. There will also be reporting provided to the merchant.

Quick Invoice Process

The detail listed below in this document explains how to use the API to create and update quick invoices. Once an invoice is created, the system will send an email with the details of the quick invoice and a link on how to make a payment towards the invoice.

The email will contain a link that looks something like the following:

https://{url}/quickinvoice/?id={quick_invoice_id}

When the end user receives this email, they will be able to click on the link and it will take them to a page that looks like the image below. This page is where they will be making their payment(s).

Once a payment is made on the quick invoice, the transaction will show up in the transaction listing with a reference to the quick invoice.

Including File Attachments

It is possible to create a QuickInvoice and attach files to it in a single request.  You just need to include all of the normally required fields along with the files and POST this data using multipart/form-data encoding. 

The following code examples demonstrate how this can be done across a few different popular languages.  You may need to extrapolate the concepts found here to whatever specific solution you are implementing.

For additional information on working with QuickInvoices and file attachments, please take a look at our File Attachments documentation further below on this page.

The url of the actual payment form payment_url

 

An example of “expanding” this endpoint to one of the above related records would look like this:

GET /v2/quickinvoices/xxxxxxxxxxxxxxxxxxxxxxxx?expand=contact

To use multiple expands on this endpoint, simply include them both separated by a comma like so:

GET /v2/quickinvoices/xxxxxxxxxxxxxxxxxxxxxxxx?expand=created_user,contact,payment_url

File Attachments

It can be useful to attach files to a Quick Invoice for many different business models, but before getting started there are some items to consider.

File Storage Service

In order to use file attachments with Quick Invoices, the File Storage Service must be enabled for the Location in which the Quick Invoice is being created. 

You can use the following request to enable the service:

POST /v2/productfiles

{
    "productfile": {
        "title": "Productfile",
        "product_file_credential_id": "{storage_credentials_id}",
        "location_id": "{location_id}}"
    }
}
Restrictions
  1. A Quick Invoice can have a maximum of 4 file attachments.
  2. Each file attachment can be a maximum of 5MB in size.
Considerations
  1. When provided, file attachments are always made available on the public facing QuickInvoice payment page where the recipient would be take to when clicking the link.
  2. By default, file attachments are NOT included in any of the QuickInvoice Notification emails.  If you want the file attachments to be included then you will need to make sure that quickinvoice.attach_files_to_email is set to 1.  This can be done in the Create request or an Update later (would need to make Resend request after Update).
  3. Some of the API interactions needed to manage files for QuickInvoices will require the using multipart/form-data encoding instead of JSON.

Attach File

The following example demonstrates how to attach a file to an existing QuickInvoice. If you are interested in uploading files at the same time you are creating the QuickInvoice, take a look at our documentation above for Including File Attachments.

POST /v2/quickinvoices/{id}/files

<?php
$client = new http\Client;
$request = new http\Client\Request;

$body = new http\Message\Body;
$body->addForm(NULL, [
  [
    'name' => 'file[file]',
    'type' => null,
    'file' => '{source_file_path}',
    'data' => null
  ]
]);

$request->setRequestUrl('https://{domain}/v2/quickinvoices/{id}/files');
$request->setRequestMethod('POST');
$request->setBody($body);

$request->setHeaders([
  'Content-Type' => 'multipart/form-data',
  'developer-id' => '{developer_id}',
  'user-api-key' => '{user_api_key}',
  'user-id' => '{user_id}'
]);

$client->enqueue($request)->send();
$response = $client->getResponse();

echo $response->getBody();
var fs = require("fs");
var request = require("request");

var options = { 
  method: 'POST',
  url: 'https://{domain}/v2/quickinvoices/{id}/files',
  headers: { 
    'Content-Type': 'multipart/form-data',
    'developer-id': '{developer_id}',
    'user-api-key': '{user_api_key}',
    'user-id': '{user_id}',
    'content-type': 'multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW'
  },
  formData: { 
    'file[file]': {
      value: 'fs.createReadStream("File {source_file_path}")',
      options: { filename: 'File {source_file_path}', contentType: null }
    }
  }
};

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});
curl -X POST \
  'https://{domain}/v2/quickinvoices/{id}/files' \
  -H 'Content-Type: multipart/form-data' \
  -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
  -H 'developer-id: {developer_id}' \
  -H 'user-api-key: {user_api_key}' \
  -H 'user-id: {user_id}' \
  -F 'file[file]=@File {source_file_path}'

DELETE /v2/quickinvoices/{id}/files/{file_id}

{
    // Empty Payload - Nothing Needed Here
}

Accessing Quick Invoice Payment Page

The public endpoint for viewing and paying the quickinvoice can utilize the quickinvoice id or the quick_invoice_api_id.

When using the Quick Invoice Id to view the Quick Invoice, the link will look as follows:

GET {url}/#/quickinvoicepay/{id}

When using Quick Invoice API Id to view the Quick Invoice, the link will look as follows, with the locsations id in the URL:

GET {url}/#/quickinvoicepay/{quick_invoice_api_id}?api_id=1&location_id={location_id}
