# Your systems hear: the moment money moves

Markdown twin of that page. Append `.md` to any Orla page URL to get one.

Orla calls an address of yours, signed, when money moves or a payment waits. Each body carries amounts and identifiers, never names.

## How it works

- **Six events, your pick.** Money in, money out, invoice paid, payout executed, payment awaiting approval and payment blocked. Pick some, or none to hear all of them, including events added later.
- **Signed, checked first.** Every call carries an HMAC signature under a secret shown once. Saving the address sends a signed ping, and an address that does not answer 2xx within ten seconds is not saved.
- **Numbers, never names.** A body carries the amount, the currency, the account, the identifiers and where the row came from. No payee names and no notes, so a leaked address gives away a number and a time.
- **Retried, then paused.** An address that does not answer is tried for about a day with growing pauses, then the subscription pauses and the owner is told. Each delivery in the journal has Retry.

## Questions

**Who can set one up?** Only an owner or an admin, because a subscription carries everything in the space without filtering by role. Pro carries one, Scale five and Enterprise twenty five.

**Will our own transfers set off our systems?** No. A move between your own accounts arrives marked internal, so a system that ships goods when money lands is not fired by your own sweep.
