# TransactionNotDevManagedGroupError

An error that indicates the transaction isn’t for a subscription that uses developer-hosted invitations.

```
object TransactionNotDevManagedGroupError
```

## Discussion

A request returns this error if you call the [`Get Seat Info`](/documentation/AppStoreServerAPI/Get-Seat-Info), [`Claim Seat`](/documentation/AppStoreServerAPI/Claim-Seat), [`Unclaim Seat`](/documentation/AppStoreServerAPI/Unclaim-Seat), or [`Associate Seat`](/documentation/AppStoreServerAPI/Associate-Seat) endpoint with an original transaction identifier for a subscription that doesn’t use developer-hosted invitations. This includes a multiseat subscription with an [`invitationManagement`](/documentation/AppStoreServerAPI/invitationManagement) value of `APPLE`, and a subscription that isn’t a multiseat purchase.

Before you call these endpoints, check that the [`TransactionMultiSeatInfo`](/documentation/AppStoreServerAPI/TransactionMultiSeatInfo) in the latest transaction for the subscription has an `invitationManagement` value of `DEVELOPER`.
