Messages

Check whether a number is on WhatsApp

Answers checked: false when the engine cannot say. Treat that as "send anyway": refusing a message because a check failed turns a missing provider feature into a delivery failure. chat_id is WhatsApp's own id for the chat when it gives one. An answer from the last 24 hours is reused (cached: true) without asking WhatsApp again. Lookups that do reach WhatsApp go through your connected number and are limited to 10 a minute per workspace, and 30 a day on Sandbox.
