Web designer or developer's guide to implementing the web widgets – Donorfy Support

This guide is designed for web developers and web designers.

How Donorfy widgets work

A web widget is HTML code that can be embedded into most modern websites to enable online donations to be collected. Donorfy provides two kinds of web widget:

for single and recurring donations by payment cards (debit/credit cards), using the Stripe payment gateway
for recurring donations by Direct Debit, using the GoCardless payment gateway

So before you can even get started creating the web pages, the client needs to set up an account with each of:

Stripe - for donations via credit/debit card - do this in Donorfy, Settings, Stripe Connect
GoCardless - for Direct Debit donations - do this in Donorfy, Settings, GoCardless Connect

That's the easy bit! Now you need to build the website pages. To do that you'll need to understand how the integration works:

The Donorfy web widget is an API that, when provided with information collected from the web page, will (a) collect the donation via Stripe or (b) set up a regular gift by Direct Debit with GoCardless, and (c) populate Donorfy with:

a new donor (we call them constituents), unless it already exists
a new donation (a Transaction - if a single donation was made)
a Recurring Payment Instruction (if a recurring donation was set up)
a Gift Aid Declaration. So it needs a combination of web design and coding skills (CSS, maybe some PHP) to arrive at a finished solution like the examples given.

You will need at least two web widgets because each widget has a number of characteristics:

whether it's Stripe or GoCardless
and the following settings which affect how the donation is categorised when it reaches Donorfy

the Product
the Campaign
the Payment Method
the Fund

User interface

The web widget code generated by Donorfy supplies a basic UI - it is provided only to illustrate the basic information that your web page needs to collect, and send it to the Donorfy API. The design of the online user journey - from clicking a Donate button, and then funnelling them through the various 'products' the client wishes to offer (one-off donations - potentially at suggested amounts, regular gifts, sponsor a (something)....) is entirely up to you and the client to design and assemble using standard features of the CMS in conjunction with your own Javascript, HTML and CSS coding skills. The final step is to pass that information to the API using the code provided so that it collects the money and updates Donorfy, as described above.

Important - you should setup your giving pages so you only have one widget on a page - if you have two widgets on the same page - even if one is hidden - the widgets will not work properly.

The important thing is to use the correct field ids, names, lengths and the hidden fields. And to call the API correctly. See below for this information.

What happens - Payment Cards via Stripe

When a donor makes a payment card donation and clicks on the Submit button, the following happens within a few seconds:

The card details are sent directly to Stripe, and Stripe returns to the website a 'token' representing that card (therefore Donorfy never stores the card details)
the donor information on the form and the token are sent to Donorfy
Donorfy collects the payment from Stripe using the token provided earlier
the donor is added (if new) to Donorfy as a new Constituent and the donation is added to the constituent's Timeline as a Transaction.
If the donor made a recurring donation by card, a Recurring Payment Instruction is added to the constituent's Timeline, and the recurring payments will be subsequently collected by Donorfy.

The process is logged and visible in Financial | Online Donations.

Website compatibility

Any modern website system should be able to accommodate a Donorfy web widget.

Your website needs an SSL certificate - so the page containing the widget needs to be https://yoursite.org/donate (for example).

Your website needs to jquery version 1.9 or later. NOTE: whilst WordPress.Org sites (the majority) do support this, their WordPress.com does not.

The Stripe widget can only use the Live Publishable Key - do not attempt to use the Test Publishable Key from Stripe.

Testing the widget

For Stripe, to do a complete end to end test you need to use a real card and submit small test donations, of say £1. You will see the donation in the constituent's Timeline.

For GoCardless you can create a live Direct Debit using real bank account information, see it in the constituent's Timeline and cancel the DD in GoCardless before it gets to claim it.

In both cases you will see the processing information logged in Financial | Online Donations.

Generating the HTML code to embed in your website

Follow these instructions to create a Stripe (cards) widget, or these instructions for a GoCardless (Direct Debit) widget.

Copy the generated HTML so that you can embed it into a page on your website.

Adding the widget to your website

Create a new page on your website. Paste the HTML that you copied in the previous step into the new page. Ensure that you are pasting it as HTML code, not as content to be displayed on the page (in WordPress for example, make sure you have the Text tab highlighted:

Modifying and styling the widget

You will want to modify the widget so that it is styled nicely into your website. You may also want to default certain values or hide fields. Within reason you can do what you like here to make the widget appear and behave as you wish.

The key things are that you must NOT change are:

The form tag
The ids, names and maximum field lengths of the input fields
The hidden fields at the end of the generated HTML - after the comment 'Do not change these values' - these are used to control the operation of the widget.

More fields on the widget
