Webhooks
Stripe Webhook
Send signup and purchase events to Cello using Stripe Webhook
Cello makes it easy to connect securely to your Stripe payment provider to automate transaction events, attribution, and payouts. Transactions are monitored and used to payout referrers based on your campaign reward rules.
Overview
A notification event is securely sent to Cello through the webhook endpoint every time a customer makes a purchase or a customer record is created or updated. Cello checks these events to perform the following actions:- Determine if a reward for referrer needs to be created and paid out
- Inform the referrer on new signups and rewards
- Cancel recurring rewards if a subscription is cancelled
If the automation of Cello detects unclear cases the automation will be paused and Cello will reach out to you to clarify the case.
Endpoint URLs
