# Hosted Payment Webhooks (https://docs.tryacme.com/reference/webhooks-hosted-payments)

> For AI agents: the documentation index is at [llms.txt](https://docs.tryacme.com/llms.txt), with every page in one file at [llms-full.txt](https://docs.tryacme.com/llms-full.txt). Each page is also available as Markdown by appending `.md` to its URL.

Example webhook bodies for hosted payments, hosted refunds and tracked QR payments.

See [how to read the webhook examples](https://docs.tryacme.com/guides/webhook-examples). The values are made up, but every
field, its order and its format match what Acme sends.
