Quo Webhooks

Quo (quo.com) is a business phone / VoIP platform. It sends webhooks for calls, messages, contacts and tasks.

Quo is the platform formerly known as OpenPhone. The support docs say so verbatim: "Send real-time notifications of Quo, formerly OpenPhone, events to your applications". The rebrand is why the legacy signature header is still called openphone-signature, and why older community material talks about OpenPhone webhooks. API host is https://api.quo.com; docs live at www.quo.com/docs and support.quo.com.

Not Quoter. Quoter (help.quoter.com) is an unrelated CPQ / sales-quoting company with an MD5-based hash form field (not a header). Quo uses HMAC-SHA256. Two different companies, two entirely different signing schemes. Also not Quora, not the Quo card/loyalty app, and not Twilio.
