Connects a WhatsApp Business Account (WABA) to ChatSyncs programmatically — a POST request since it creates/updates a connection, and because access_token is sensitive and shouldn’t be sent as a GET query parameter.
Where to find user_id: call Get My Info first — copy the user_id value from its response and use that here.
Where to find whatsapp_business_account_id and access_token: for a first-time connection, both come from Meta, not ChatSyncs — see Meta Developer Account Setup. If the WABA is already connected, whatsapp_business_account_id is also shown right on the same WhatsApp → Connect Account card as phone_number_id — see Finding Your IDs & API Token for a screenshot.
