Payment Link (Checkout Page)

You can use our MixPay payment page to create a MixPay payment. Payment link is the most convenient way of integrating MixPay.

We provide 3 types of payment links:

1. Permanent Payment Link: This type of link can be customized and can be used for multiple payments. If you need to implement a long-term payment function, such as a donation, this type of link is a good choice. You can create a permanent payment link quickly in Dashboard Payment Link.
2. One-time Payment Link: This type of link can only be used for a single payment. If you need to implement a one-time payment function, such as a bill, this type of link is a good choice.You can create a permanent payment link quickly in Dashboard Billing.
3. Universal Payment Link: This type of link can achieve the functions of both permanent payment link and One-time payment link by customizing parameters, but the link cannot be personalized. If you need to implement a simple payment function, this type of link is a good choice.

Start with an example.

Here is an example of universal payment link, click the following button and check it out yourself:

IMPORTANT: The example is for new users to understand how the MixPay payment flow. We recommend using One-time Payment Link in the production.

Although this method is more convenient, and you may be more inclined to use this method of splicing parameters, you need to pay attention that when using this method, people can easily in the browser change the parameters you set.
