   Events API

   ](https://smashsend.com/integrations/events)

Turn every user event into an automated email

Send custom events from your product—signups, purchases, feature usage, anything—and trigger perfectly-timed campaigns based on what your users actually do. Use the Events API directly, or stream events from the analytics stack you already run.

curl "https://smashsend.com/v1/events" \ -H "Authorization: Bearer sk_..." \ -H "Content-Type: application/json" \ -d '{ "name": "purchase_completed", "email": "user@example.com", "properties": { "plan": "pro", "amount": 49 } }'

Behavior-driven email, without the busywork

Track any event

Define your own event schemas with custom properties. Capture signups, purchases, feature adoption, churn signals—whatever matters to your business.

Trigger automations

Start a workflow the moment an event arrives. Welcome flows, onboarding nudges, win-backs and upsells fire automatically based on real behavior.

Segment in real time

Event properties update contacts instantly, so your segments and personalization always reflect the latest state of every user.

How it works

From event to email in three steps

1

Send an event

Your app POSTs an event to the Events API, or your analytics tool streams it in automatically.

2

Match a contact

SMASHSEND attaches the event to the contact and updates their properties in real time.

3

Trigger the automation

A workflow listening for that event fires and sends the right email at the right moment.

• Nudge users who started but never finished a key action
• Win back accounts that show churn signals or go inactive
• Celebrate milestones and reward power users automatically
• Promote a feature the moment a user adopts a related one
