Developer platform
Add Buddy infrastructure to your own product.
Buddy API gives developers programmatic access to the same customer-engagement primitives inside Buddy: subscribers, audiences, consent, events, automation, messaging, and analytics. Your product keeps its own UI while Buddy handles the WhatsApp engagement layer.
Developer surface
Build against the same audience engine Buddy uses.
Buddy API is for teams that need customer engagement primitives in code: subscribers, consent, audiences, events, messaging status, replies and webhooks. Your product stays the front door while Buddy powers the WhatsApp relationship layer underneath.

Use predictable APIs for subscriber identity, customer events and messaging outcomes, then keep your system updated through webhooks and logs.
Create or match a subscriber: Attach identity, phone, source, consent, and external IDs from your product.
Record meaningful activity: Send an event when the customer buys, signs up, books, enrolls, renews, abandons, or fails payment.
Trigger the next action: Let Buddy update an audience, start a journey, or prepare an approved WhatsApp message.
Receive the outcome: Use webhooks to sync delivery, read, reply, failed, opt-out, campaign, and automation events.
A developer workflow that stays close to the customer.

Sandbox first
Developers should be able to test payloads, errors, idempotency, and webhook delivery before production.
Scoped access
API credentials should be limited to the workspace and actions required for the integration.
Official platform constraints
Messages still need to respect WhatsApp Business Platform rules, templates, consent, and account status.
