# transactionReason

The cause of a purchase transaction, which indicates whether it’s a customer’s purchase or a renewal for an auto-renewable subscription that the system initiates.

## Declaration

```data
string transactionReason
```

## Possible Values

PURCHASE: The customer initiated the purchase, which may be for any in-app purchase type: consumable, non-consumable, non-renewing subscription, or auto-renewable subscription. RENEWAL: The App Store server initiated the purchase transaction to renew an auto-renewable subscription.

## Discussion

Discussion If a customer upgrades an auto-renewable subscription, the upgrade is effective immediately and the transactionReason is PURCHASE. If a customer downgrades an auto-renewable subscription, the product change occurs on the subscription renewal date. The resulting transactionReason is RENEWAL.
