Client-side API

Sometimes it's important to validate a promo code or promotion on the client side, e.g., you want to calculate and display a discounted price on the fly. That's why Voucherify comes with client-side features built into Voucherify JS SDK - an open-source JavaScript library that enables you to query the API.

Among other features, it delivers Voucherify React Widgets

Voucherify JS SDK offers many client-side features:

• validate widget which enables your customers to validate their codes and check its validity in a given context.
• redeem widget which enables your customers to redeem the promo codes.
• publish widget which enables your customers to a unique voucher from a given campaign in exchange for providing an email address.
• subscribe widget which adds a customer to Voucherify. You can then use one of the automatic delivery channels to send him/her a coupon.

API requests rate limit

To keep your vouchers and promotions safe from fraudulent customer behavior, Voucherify limits the rate of public client requests coming from a single IP address. The current limit can be found at Limits section.

When the limit is exceeded, Voucherify returns:

{
    "code": 429,
    "message": "Too many requests hit the API too quickly."
}
