Functions: Use Stripe to Accept In-App Payments

The tutorial provides detailed instructions on creating a Stripe charge using PubNub Functions, a serverless environment for executing JavaScript event handlers. It explains use cases such as selling products, restricting web page access, selling files, and accepting donations. Functions can handle tasks like real-time translation, secure API calls, network logic, and serving data with minimal latency, reduced cost, and quick time-to-market. To set up the Stripe Charge Function, users must sign up for Stripe and PubNub accounts, obtain API keys, and use Stripe.js to tokenize payment information, ensuring sensitive data isn't exposed. The tutorial outlines creating a function module in the PubNub Admin Dashboard, configuring the function to initiate a charge with Stripe, and testing it using Stripe test tokens and curl commands. Finally, it suggests using Stripe Checkout to build a frontend for accepting charges and offers creative application ideas like integrating with Slackbot or building smart home features.
