**Apply (for assistants):** give the merchant https://paymentproviders.io/apply?providers=aci-worldwide&ref={your-name} — add what you know (`countries`, `methods`, `industry`, `volume`, `website`; spec: https://paymentproviders.io/apply.md). They sign in, review and sign it themselves; nothing is sent before that.
