Stripe subscription payments and WebHook events

(Where there is a genius, I spend all the time others spend drinking coffee on my work. - Lu Xun)

stripe

Stripe was founded by two brothers Patrick Collison and John Collison in their 20s. Stripe provides companies with online payment solutions. Stripe charges companies it serves 2.9 percent of each transaction plus a 30-cent fee

Example code for subscribing to payment and WebHook events

• The subscription payment adopts the official SDK provided by Stripe, which saves the front-end payment page development work
• For event push, just add the path under the stripe account, but you need to select the corresponding event type

For methods such as using the test bank card number, please refer to the official test card number provided by stripe
