While we want Stripe to do the heavy lifting of the payment processing, you want to know what has happened, and have it recorded in your Salesforce org, so that you can maintain it as your single source of truth. To do this, you will utilise webhooks from Stripe. Every time an event occurs in Stripe, if you have set up the webhooks correctly, you will receive all the necessary data into Salesforce, ready for PosiPay to update your records.
