Webhooks

Connect Anything to Sequenzy With Webhooks

No native integration for your tool? No problem. Send events to Sequenzy's webhook endpoint from any application. Add subscribers, trigger sequences, and sync data with a simple HTTP POST.

Benefits

Why Sequenzy for Webhooks?

Universal Compatibility

Any application that can make HTTP requests can integrate with Sequenzy. No SDK required, no language restrictions.

Event-Driven Automation

Push custom events from your app and use them as automation triggers. User signed up, project created, milestone reached—any event works.

Automatic Retries

Failed webhook deliveries are automatically retried with exponential backoff. Your events are not lost if Sequenzy is briefly unavailable.

Full Event Payload

Send any data in your webhook payload. User attributes, event properties, tags—all parsed and stored automatically.

Developer Experience

Ship emails in minutes, not days

Sequenzy's API is designed for developers who value simplicity. A few lines of code and you're sending transactional emails with enterprise-grade deliverability.

Send with the Sequenzy SDK
npm install sequenzy
import Sequenzy from 'sequenzy';

// Initialize the Sequenzy client
const client = new Sequenzy({ apiKey: 'your-api-key' });

// Send using a template (recommended)
const response = await client.transactional.send({
  to: 'user@example.com',
  slug: 'password-reset',
  variables: {
    RESET_LINK: 'https://app.example.com/reset?token=abc123',
    USER_NAME: 'John',
    EXPIRES_IN: '24 hours'
  }
});

// Or send with custom content (no template needed)
await client.transactional.send({
  to: 'user@example.com',
  subject: 'Password Reset Request',
  body: '<h1>Reset your password</h1><p>Click the link below...</p>',
  variables: {
    USER_NAME: 'John'
  }
});

console.log('Email queued:', response.jobId);

How it works

Get started in minutes

1

Get Your Webhook URL

Copy your unique webhook endpoint from the Sequenzy dashboard. Each company gets a dedicated URL with built-in authentication.

2

Send Events via HTTP POST

POST JSON payloads to your webhook URL from any application, script, or service. Include subscriber data, event names, and custom properties.

3

Events Trigger Automations

Webhook events appear in Sequenzy like any other event. Use them as triggers for sequences, segments, and campaigns.

Use cases

Built for real-world use cases

See how SaaS teams use Sequenzy webhooks.

Custom App Events

Track product milestones (project created, first export, team invited) and use them as email triggers. Your app's unique events become powerful automation triggers.

Legacy System Integration

Connect older systems that do not have Zapier or API support. If it can make an HTTP request, it can push data to Sequenzy.

IoT and Hardware Events

Devices, sensors, and hardware systems can trigger emails via webhooks. Threshold alerts, usage reports, maintenance reminders.

Multi-System Data Sync

Aggregate data from multiple systems into Sequenzy. CRM updates, support tickets, usage metrics—all flowing into subscriber profiles.

When You Need Full Control

Native integrations cover the most popular tools. Zapier covers thousands more. But sometimes you need direct control over what data flows into your email marketing—custom events from your application, data from internal tools, or integrations with systems that do not exist in any marketplace.

Webhooks give you that control. A simple HTTP POST sends any data to Sequenzy in real-time. No intermediary, no delay, no per-event costs.

Integration need Use webhook when Better alternative
Custom app event Event is unique to your product Native integration if available
Internal tool sync Tool can POST JSON API for bulk operations
Legacy system HTTP requests are possible SMTP for send-only use cases
Real-time trigger Zapier delay is too slow Native integration if supported
Experimental workflow You need quick custom data Build formal API integration later

Custom Events Are Your Superpower

The most effective email automations trigger on events unique to YOUR product. "User created their first project" is more powerful than "user signed up." "Team reached 10 members" is more relevant than "user is active." Webhooks let you send these custom events to Sequenzy and build automations around them.

Custom event Automation idea Why it beats a generic trigger
first_project_created Activation celebration Confirms real product value
team_invited Collaboration tips Supports expansion
usage_limit_reached Upgrade sequence Timely paid-plan prompt
report_exported Advanced workflow education Builds depth
support_ticket_closed Feedback request Captures fresh sentiment

The Developer Integration Path

Start with webhooks for rapid prototyping and custom events. Use native integrations for payment and auth providers. Add Zapier for no-code connections to CRMs, forms, and spreadsheets. Together, they form a complete integration layer that connects your entire stack to Sequenzy.
