LaterPay Purchase Button and Purchase Links

LaterPay’s mission is to make buying digital content as convenient as possible.
An important part of this is to provide a consistent user experience across all websites that use LaterPay. Here are a few guidelines to ensure purchasing with LaterPay is as easy as possible for your users. Most of the guidelines are not mandatory, but there are a few rules you should keep in mind.
Required Elements¶
Please make sure our purchase button contains all required elements:
A LaterPay purchase button or link must include (at minimum)
The LaterPay Cart icon
The price
The currency (as a currency sign (e.g. “$”) or currency code (e.g. “USD”))
Price and currency are only mandatory if they aren’t stated very close to the purchase button or link already

Call-To-Action Text¶
Additionally, you may want to add call-to-action text in the purchase button or link. If you do, please make sure that the copy clearly reflects what the user can expect after clicking this purchase button or link.

Shape¶
A LaterPay purchase button can have any shape as long as your users can recognize it as a clickable element and it contains all the necessary information (see above). We recommend a rectangular shape with a corner radius of 3px.
Color and Contrast¶
You may choose the color of your LaterPay purchase button or link and its text color freely. Please make sure that both
The contrast between the button’s or link’s background and the button or link itself
And the contrast between the button’s background color and its text color
are sufficiently high (for more information about accessibility please see here).
