How do I unlock membership automatically after a successful payment?
A mechanism where the other party proactively notifies an address you configured when something happensWhen events like successful payments or git pushes occur, the external platform immediately sends an HTTP request to your configured endpoint so your service can react. Compared to polling every few seconds, webhooks are instant and bandwidth-efficient; however, your endpoint must verify signatures against spoofing and deduplicate repeated retries.
