How to Build Workflow Automations with ClinikAPI Event Flow (Webhooks, SMS Reminders, Billing Sync)

Quick Answer

ClinikAPI's Event Flow lets you subscribe to real-time clinical events — patient created, appointment booked, encounter finished, prescription written — and trigger automations in your application. When an appointment is booked, send an SMS reminder. When an encounter is completed, sync the billing system. When a new patient signs up, trigger an onboarding workflow. You listen for webhook events, and your code decides what happens next. No polling. No cron jobs. Real-time.

Why Static EHRs Are Not Enough

Most EHR systems are databases with a UI on top. Data goes in. Data comes out. Nothing happens in between.

But real clinical workflows are dynamic. When a patient books an appointment, they should get a confirmation text. When a provider finishes an encounter, the billing system should generate a claim. When a lab result comes back abnormal, the care team should be notified. When a prescription is written, the pharmacy should be alerted.

In a traditional EHR, all of this requires manual work or clunky integrations. With ClinikAPI's Event Flow, it happens automatically.

How Event Flow Works

Event Flow is ClinikAPI's real-time event system. Every time something happens in your ClinikAPI data — a resource is created, updated, or deleted — an event is fired. You subscribe to the events you care about, and ClinikAPI sends a webhook to your endpoint.

Clinical Action → ClinikAPI → Event Generated → Webhook Sent → Your Code Runs

Example flow:

1. A patient books an appointment via your app
2. Your app calls clinik.appointments.create()
3. ClinikAPI stores the appointment and fires an appointment.created event
4. ClinikAPI sends a webhook POST to your registered endpoint
5. Your endpoint receives the event payload with the appointment details
6. Your code sends an SMS confirmation to the patient

All of this happens in under a second.

5 Automations You Can Build Today

1. SMS Appointment Reminders

The most common automation. When an appointment is booked, send a confirmation. 24 hours before, send a reminder. After the visit, send a follow-up.

Webhook event: appointment.created

// Your webhook endpoint (Next.js API route)
export async function POST(req: Request) {
  const event = await req.json();

  if (event.type === 'appointment.created') {
    const appt = event.data;

    // Send confirmation SMS via Twilio
    await twilio.messages.create({
      to: appt.patientPhone,
      from: '+1234567890',
      body: `Your appointment is confirmed for ${formatDate(appt.start)}. 
             Reply C to cancel or R to reschedule.`,
    });

    // Schedule a 24-hour reminder
    await scheduleReminder({
      patientPhone: appt.patientPhone,
      appointmentId: appt.id,
      sendAt: subtractHours(appt.start, 24),
      message: `Reminder: You have an appointment tomorrow at ${formatTime(appt.start)}.`,
    });
  }

  return Response.json({ received: true });
}

Impact: Clinics that send automated reminders see 30-50% fewer no-shows.

2. Billing Sync on Encounter Completion

When a provider finishes an encounter and marks it complete, automatically generate a billing record in your billing system.

Webhook event: encounter.updated (status changed to finished)

if (event.type === 'encounter.updated' && event.data.status === 'finished') {
  const encounter = event.data;

  // Fetch the full encounter with observations and prescriptions
  const { data } = await clinik.encounters.read(encounter.id, {
    include: ['Observation', 'MedicationRequest'],
  });

  // Generate billing codes based on encounter data
  const billingRecord = {
    patientId: encounter.patientId,
    encounterId: encounter.id,
    date: encounter.date,
    codes: extractCPTCodes(data),
    diagnoses: extractICDCodes(data),
  };

  // Send to your billing system
  await billingSystem.createClaim(billingRecord);
}

Impact: Eliminates manual billing entry. Claims are generated the moment the encounter ends.

3. Care Team Notifications

When a critical observation is recorded — abnormal lab result, high blood pressure, concerning assessment score — notify the care team immediately.

Webhook event: observation.created

if (event.type === 'observation.created') {
  const obs = event.data;

  // Check if the value is outside normal range
  if (obs.flag === 'high' || obs.flag === 'critical') {
    // Notify the care team via Slack, email, or pager
    await slack.postMessage({
      channel: '#clinical-alerts',
      text: `⚠️ Abnormal result for patient ${obs.patientId}: 
             ${obs.code} = ${obs.value} ${obs.unit} (${obs.flag})`,
    });

    // Also send an email to the assigned provider
    await sendEmail({
      to: obs.providerEmail,
      subject: `Abnormal Result: ${obs.code}`,
      body: `Patient ${obs.patientId} has an abnormal ${obs.code} reading.`,
    });
  }
}

Impact: Critical results are flagged in real-time instead of waiting for the next chart review.

4. Patient Onboarding Workflow

When a new patient is created, automatically trigger an onboarding sequence: send a welcome email, create intake forms, schedule a reminder to complete them.

Webhook event: patient.created

if (event.type === 'patient.created') {
  const patient = event.data;

  // Send welcome email
  await sendEmail({
    to: patient.email,
    subject: 'Welcome to Our Practice',
    template: 'welcome-patient',
    data: { firstName: patient.firstName },
  });

  // Create intake form request
  await clinik.intakes.create({
    patientId: patient.id,
    responses: [], // Empty — patient will fill in
  });

  // Schedule a reminder if intake not completed in 48 hours
  await scheduleTask({
    type: 'intake-reminder',
    patientId: patient.id,
    runAt: addHours(new Date(), 48),
  });
}

5. Prescription Pharmacy Alerts

When a prescription is created, notify the pharmacy or trigger an e-prescribe workflow.

Webhook event: prescription.created

if (event.type === 'prescription.created') {
  const rx = event.data;

  // Send to pharmacy system
  await pharmacyAPI.submitPrescription({
    patientId: rx.patientId,
    medication: rx.medication,
    dosage: rx.dosage,
    prescriberId: rx.practitionerId,
  });

  // Notify patient
  await sendSMS({
    to: rx.patientPhone,
    body: `Your prescription for ${rx.medication} has been sent to your pharmacy.`,
  });
}

Setting Up Webhooks

Step 1: Register your endpoint

In the ClinikAPI developer portal, add your webhook URL and select which events you want to receive.

Step 2: Build your endpoint

Your endpoint receives POST requests with a JSON payload containing the event type and data. Verify the webhook signature to ensure it came from ClinikAPI.

export async function POST(req: Request) {
  // Verify webhook signature
  const signature = req.headers.get('x-clinikapi-signature');
  const body = await req.text();

  if (!verifySignature(body, signature, process.env.WEBHOOK_SECRET!)) {
    return Response.json({ error: 'Invalid signature' }, { status: 401 });
  }

  const event = JSON.parse(body);

  // Route events to handlers
  switch (event.type) {
    case 'appointment.created':
      await handleAppointmentCreated(event.data);
      break;
    case 'encounter.updated':
      await handleEncounterUpdated(event.data);
      break;
    case 'observation.created':
      await handleObservationCreated(event.data);
      break;
    case 'patient.created':
      await handlePatientCreated(event.data);
      break;
    case 'prescription.created':
      await handlePrescriptionCreated(event.data);
      break;
  }

  return Response.json({ received: true });
}

Step 3: Handle failures gracefully

Webhooks can fail (your server is down, network issues, etc.). ClinikAPI retries failed webhooks with exponential backoff. Your endpoint should return a 200 status quickly and process the event asynchronously if the work takes time.
