Whop Connection Setup

Connect Flexprice to Whop to sync invoices and reconcile payments automatically

Overview

A Whop connection in Flexprice lets you:

• Sync invoices - push finalized Flexprice invoices to Whop
• Generate payment links - every synced invoice gets a Whop-hosted payment URL
• Reconcile payments - payment status is kept in sync between Whop and Flexprice automatically

Prerequisites

Before you start, have:

1. Whop business account - whop.com
2. Flexprice account - flexprice.io

Keys you need

Key	Where to get it	What it’s for
API Key	Whop Dashboard → Developer → API Keys → Create → select Admin role	Authenticating all Whop API calls from Flexprice
Company ID	View your business profile on Whop → click the three-dot menu (…) → Copy ID	Your Whop business identifier (biz_...)
Product ID (optional)	Whop Dashboard → Products	Which Whop product invoices are grouped under - leave blank and Flexprice creates one automatically

How to connect your Whop account

Go to Flexprice Dashboard → Settings → Integrations → Whop → Add a connection.

1. Name your connection

   Enter a name to identify this connection, e.g. Whop Production.

2. Enter API Key and Company ID

   • API Key - starts with apik_. Go to Whop Dashboard → Developer → API Keys → Create, enter a name, and select the Admin role.
   • Company ID - starts with biz_. Open your business profile on Whop, click the three-dot (…) menu in the top right, and select Copy ID.
3. Product ID (optional)

   If you have an existing Whop product, enter its ID (prod_...).

   Leave blank - Flexprice will automatically create a product called Flexprice Billing Product on the first invoice sync and reuse it for all future invoices.

4. Enable Invoice Sync

   Toggle Invoice Sync on to push finalized invoices to Whop. With this off, invoices stay only in Flexprice.

5. Copy your Webhook URL

   At the bottom of the drawer, copy your webhook URL. You will need it in the next step.

   The URL format depends on your region:

   Region	Webhook URL
   US	https://us.api.flexprice.io/v1/webhooks/whop/{tenant_id}/{environment_id}
   India	https://api.cloud.flexprice.io/v1/webhooks/whop/{tenant_id}/{environment_id}

Configure Webhook in Whop

For Flexprice to mark invoices as paid when payment is completed through Whop, register your webhook URL in Whop.

1. Open Whop Webhook Settings

   Go to your Whop Dashboard → Settings → Webhooks → Add Endpoint.

2. Paste the Webhook URL

   Paste the URL copied from the Flexprice connection drawer.

3. Subscribe to events

   Select the following events and save:

   Event	Purpose
   invoice_paid	Marks the Flexprice invoice as paid when payment completes
   payment_succeeded	Enables Charge Automatically for future invoices

Without the webhook configured, invoices synced to Whop will not automatically mark as paid in Flexprice and Charge Automatically will not activate.

Troubleshooting

Issue	Cause	Solution
Invoice not syncing to Whop	Invoice sync toggle is off	Enable outbound sync in connection settings
Sync fails - customer error	Customer has no email address	Add an email to the customer in Flexprice before finalizing the invoice
Webhook events not received	Wrong URL or events not subscribed	Re-copy the URL from the drawer and confirm both invoice_paid and payment_succeeded are selected in Whop

Next Steps

1. Finalize a test invoice in Flexprice and verify it appears in your Whop dashboard
2. Check the invoice in Flexprice for whop_checkout_url in the metadata
3. Pay the Whop invoice and confirm the Flexprice invoice is marked paid
