WhatsApp marketing API

The API lets your marketing stack send WhatsApp campaigns and alerts programmatically, so promotions and updates reach contacts on a channel they read. A Beam agent assembles a campaign from your list and template, applies your rule about consent and timing, and issues the messages to contacts who qualify. When a contact lacks opt in, or a template would breach the rules you set for frequency, the agent excludes them and notifies a marketer, so the send respects preferences instead of blasting everyone on the list regardless of whether they agreed to it.

Notification campaigns

Beyond promotions, the service carries operational notices like offers, reminders, and status alerts to WhatsApp. A Beam agent reads the trigger from your marketing automation, applies your rule to pick the audience and message, and updates each contact record to log what was sent and when. If a campaign targets an audience larger than your approved cap, or overlaps a message a contact just received, the agent pauses and routes it to a person to confirm, preventing the fatigue that pushes recipients to block or report the sender.

Contact list messaging

Campaigns run against segmented lists, so different groups receive messages suited to them rather than one blanket blast. A Beam agent reads the segment definition, applies your rule to build the recipient set, and writes delivery and reply outcomes back for reporting. When a contact appears in conflicting segments, or a reply signals an unsubscribe request, the agent flags it for a person and updates preferences, so someone handles the opt out properly instead of letting the next campaign message a customer who asked to stop.
