Outcome
Add WhatsApp engagement without rebuilding the engine.
The developer platform gives products and platforms access to Buddy primitives: workspaces, subscribers, consent, audiences, events, automations, messages, templates, analytics, webhooks, and connections.
Developer platform
REST
API style
HMAC
webhook signing
Scopes
workspace permissions
Build without touching production.
Messaging infrastructure gets complex fast.
A useful WhatsApp layer needs consent, customer identity, templates, delivery state, retries, replies, opt-outs, permissions, billing realities, and platform policies. Buddy packages that into infrastructure developers can build on.
Audience APIs
Create, update, tag, and organize subscribers and audiences from your own product while preserving source, identity, and consent context.
Event APIs
Tell Buddy when meaningful activity happens: purchase completed, checkout abandoned, subscription started, trial expiring, booking created, course enrolled, or payment failed.
Messaging APIs
Create or trigger approved messaging workflows and connect message state back into your product through delivery and engagement updates.
Webhooks
Receive subscriber, campaign, message, and automation events so your own systems stay synchronized with what happened in Buddy.
OAuth and SDKs
Let customers authorize access securely, then build faster with SDKs that wrap authentication, events, webhooks, and common API workflows.
Create credentials
Use test and live credentials with scoped access and predictable permissions.
Send simulated data
Validate subscribers, events, payloads, idempotency, and error handling before real customer activity flows.
Subscribe to webhooks
Confirm delivery, read, reply, failure, opt-out, and automation events in your own environment.
Go live carefully
Move from sandbox to production with logs, limits, consent, and approval flows in place.
