What is Polar?

Polar is a modern payment platform designed for developers, open source maintainers, and digital product creators. It offers subscriptions, one-time payments, and benefits management with a developer-friendly API.

​
Connecting Polar

Unlike Stripe (which uses an app integration), Polar requires manual API key and webhook setup. Here’s how to connect:

​
Step 1: Get Your Polar API Key

  1. Go to your Polar Dashboard
  2. Navigate to Settings in your organization
  3. Click API & Webhooks
  4. Create a new Organization Access Token
  5. Copy the token (format: polar_oat_xxxxxxxxx)
Your API token is only shown once. Store it securely before closing the dialog.

​
Step 2: Set Up Webhooks in Polar

  1. In Polar, go to Settings → Webhooks
  2. Click Create Webhook Endpoint
  3. Enter your Sequenzy webhook URL:
    You can find this URL in Sequenzy when connecting Polar—it’s automatically shown in the connection modal.
  4. Select these events to listen for:
    • subscription.created
    • subscription.active
    • subscription.updated
    • subscription.canceled
    • subscription.uncanceled
    • subscription.revoked
    • order.created
    • order.paid
    • checkout.expired
    • customer.created
    • customer.state_changed
  5. Click Create to save the webhook
  6. Copy the Webhook Secret (format: polar_whs_xxxxxxxxx)
Already connected? Polar only delivers the events selected on your existing webhook endpoint. Edit it in Polar → Settings → Webhooks and make sure checkout.expired and subscription.uncanceled are checked - otherwise abandoned-checkout tracking and trial-reactivation handling will not receive their events.

​
Step 3: Connect in Sequenzy

  1. Go to Settings → Integrations in Sequenzy
  2. Click Connect next to Polar
  3. Enter your:
    • API Key (from Step 1)
    • Webhook Secret (from Step 2)
  4. Click Connect Polar
Sequenzy will immediately begin syncing your existing Polar customers.

​
Synced Attributes

When connected, Sequenzy adds these attributes to each subscriber matched by email:

​
MRR Calculation

MRR is normalized from any billing interval:
  • Monthly: Used as-is
  • Yearly: Divided by 12
  • Weekly: Multiplied by 52, then divided by 12
  • Daily: Multiplied by 365, then divided by 12
Only active subscriptions count toward MRR.

​
LTV Calculation

LTV sums all successful orders for a customer, minus any refunds. This gives you the true lifetime value accounting for partial refunds.

​
Automatic Tags

Sequenzy automatically applies tags to subscribers based on their Polar subscription status: These tags update automatically whenever subscription status changes - both from live webhooks and from Sync Revenue runs, which apply the same rules.

​
Tracked Events

When you connect Polar, these events are automatically tracked for use in automations:
Polar does not send a trial-ending webhook, so Sequenzy schedules saas.trial_will_end itself when a trial starts - about 3 days before the trial’s end, matching Stripe’s timing. The reminder is cancelled automatically if the trial converts, is cancelled, or churns first, so automations built on this event never reach someone who already decided.

​
Using Revenue Data

​
Building Segments

With MRR and LTV synced as numeric attributes, you can create sophisticated segments: Revenue-based segments:
  • mrr >= 100 — High MRR customers
  • ltv > 1000 — Lifetime high-value customers
  • mrr >= 50 AND mrr < 200 — Mid-tier customers
Combining with tags:
  • tag = churned AND ltv > 500 — High-value churned customers (win-back targets)
  • tag = cancelled AND mrr >= 100 — At-risk high-value customers needing attention
  • tag = saas.yearly AND mrr >= 100 — Yearly enterprise customers

​
Automations

Trigger automations when revenue attributes change:
  • Send a thank-you email when ltv exceeds a threshold
  • Trigger a win-back sequence when a subscriber gets the churned tag
  • Notify your team when a high-value customer cancels

​
Manual Sync

To re-sync revenue data at any time:
  1. Go to Settings → Integrations
  2. Find your connected Polar account
  3. Click Sync Revenue
The sync processes all Polar customers and updates matching subscribers.

​
How Matching Works

Subscribers are matched by email address (case-insensitive). A Polar customer with email User@Example.com will match a subscriber with email user@example.com. If a Polar customer doesn’t have an email or doesn’t match any subscriber, they’re skipped during sync.

​
Troubleshooting

​
Webhooks Not Arriving

  1. Verify your webhook URL is correct in Polar settings
  2. Check that you’ve selected the correct events
  3. Ensure your Polar organization has the webhooks:write scope
  4. Check Polar’s webhook delivery logs for failed attempts

​
Customers Not Syncing

  1. Ensure the customer email in Polar matches a subscriber in Sequenzy
  2. Try clicking Sync Revenue to force a re-sync
  3. Check that your API key has the required scopes:
    • customers:read
    • subscriptions:read
    • orders:read

​
Invalid Webhook Signature

If webhooks are failing with signature errors:
  1. Verify you copied the complete webhook secret from Polar
  2. Re-create the webhook in Polar and update the secret in Sequenzy
  3. Ensure the secret starts with polar_whs_
