Capabilities

The full Meta Cloud API, hardened for African networks.

From template management to media uploads, every WhatsApp surface is covered — with delivery analytics that tie out against Meta's billing.

Templates

Approved templates in 30+ languages.

Submit, version, and roll out — without filing tickets with Meta.

Two-way chat

Webhook in, REST out.

Build agent inboxes, chatbots, or hybrid flows on the same API.

Media

Image, document, audio, video.

Receipts, contracts, proof-of-delivery photos — through one endpoint.

Broadcasts

Bulk-send to opted-in audiences.

With per-recipient delivery receipts and conversation tracking.

Compliance

Opt-in, opt-out, and audit trails.

Meta policy honoured automatically; full audit logs retained.

Two lines of code

Send a template-driven WhatsApp message in seconds.

Channel routing is implicit. Hit the same /messages endpoint as SMS; specify channel: whatsapp and a pre-approved template name. Black Konnect handles the rest.
