How do I notify my application or web service when a subscription has been canceled?

You can notify your application or web service about cancellations in Zoho Subscriptions by using Webhooks. Here’s how:

• Go to Settings > Automation > Webhooks.
• Click + New Webhook.
• Enter a name for your webhook and select the module as Subscriptions.
• Select Cancel Subscription in the Predefined Events section.
• Configure the rest of the webhook and click Save.

Now, this webhook will be triggered whenever a subscription has been canceled in Zoho Subscriptions.
