Overview

AppSumo uses webhooks to notify partners when a license for their product is purchased, activated, upgraded, downgraded, or deactivated.

What is a Webhook?

A webhook, or web callback, is a way for apps to send real-time data to other applications automatically. Unlike standard APIs that require constant polling, webhooks push data immediately when events happen, making them more efficient.

AppSumo Webhook Event Types

AppSumo sends the following webhook events related to your product’s licenses:

• purchase: Triggered when a user buys your product.
• activate: Triggered when a user activates their purchase.
• upgrade: Triggered when a user upgrades their product tier (e.g., Tier 1 to Tier 2).
• downgrade: Triggered when a user downgrades their product tier (e.g., Tier 2 to Tier 1).
• migrate (add-on specific): Triggered during both upgrade and downgrade events specifically related to deal add-ons. This event serves as a ledger record, assuming the association with the newly upgraded or downgraded parent deal has already been established through the upgrade/downgrade webhook.
• deactivate: Triggered when a license is deactivated, often due to a refund or cancellation.

Test Webhooks

Test webhooks validate your webhook URL and include "test": true in the POST request. These should not trigger actions within your product but should respond successfully to confirm your URL is working.
