The API works this way:
- You register a webhook URL
- We send updates and information to the webhook URL you have specified
You can subscribe to published event types by registering webhooks. You will then be notified when any matching events are published for the given sales unit's Merchant Serial Number.
As an example, a merchant can register a callback URL to receive a callback when any of the merchant's payments are captured.
You can register a set number of webhooks per event type for each sales unit. See Register webhook for details.
