An indicator of whether an auto-renewable subscription is in the introductory price period.

```
string is_in_intro_offer_period
```

## Discussion

This field is returned in the JSON response, in the [`responseBody.Latest_receipt_info`](/documentation/AppStoreReceipts/responseBody/Latest_receipt_info-data.dictionary) and [`responseBody.Receipt.In_app`](/documentation/AppStoreReceipts/responseBody/Receipt-data.dictionary/In_app-data.dictionary) arrays.

You can use this value to determine if the user is eligible for introductory pricing. If a previous subscription period in the receipt has the value `“true”` for either the [`is_trial_period`](/documentation/AppStoreReceipts/is_trial_period) or `is_in_intro_offer_period` keys, the user is not eligible for a free trial or introductory price within that subscription group.
