The [docs](https://www.revenuecat.com/docs/webhooks#webhook-events) don’t mention about the event type when a promo code is used for a subscription.
As soon as the user redeems a code, I want to get a webhook event so that I can update user’s data on my backend. How can I then do it?
Hi,
This is a great question.
When the promo is purchased, a webhook will come in with the following fields,
"period_type": "PROMOTIONAL",
"type": "NON_RENEWING_PURCHASE"When it expires,
"period_type": "PROMOTIONAL",
"type": "EXPIRATION"When it comes to syncing customer information to your database, we do recommend using the webhooks only as a trigger to call our API. You can find more information about this here.
Thanks for the answer.
Does it also mean that the user won’t be charged once the subscription (via promo code) expires? I think they must be charged as there’s no such thing as “Free subscription” but “Free trials to subscription”.
