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

​

Before you start, have:
  1. Whop business account - whop.com
  2. Flexprice account - flexprice.io

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:
RegionWebhook URL
UShttps://us.api.flexprice.io/v1/webhooks/whop/{tenant_id}/{environment_id}
Indiahttps://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 invoice.paid

Select the invoice.paid event and save.
Without the webhook configured, invoices synced to Whop will not automatically mark as paid in Flexprice when payment is completed. You would need to reconcile payments manually.
