Create an In-App Purchase key
Generate the In-App Purchase key (Issuer ID, Key ID, and .p8 file) that Voidhash uses to verify StoreKit transactions.
The In-App Purchase key lets Voidhash verify StoreKit 2 transactions and look up purchase data
through the App Store Server API. You collect three values from App Store Connect: the Issuer
ID (a team-wide UUID), the Key ID (a 10-character identifier), and the .p8 private key
file.
Open the Integrations keys
In App Store Connect, go to Users and Access, open the Integrations tab, and select In-App Purchase under Keys. You need the Account Holder or Admin role to generate keys.
Generate a key
Click Generate In-App Purchase Key, or the + icon if you already have one. Give the key a
name such as Voidhash and create it. The name is for your reference only, and you cannot edit
it afterwards.
Copy the Issuer ID and Key ID
The Key ID is the 10-character identifier shown in the key's row under Active. Copy it into the Key ID field in Voidhash.
The Issuer ID is shown at the top of the keys page. Copy it into the Issuer ID field.
If no Issuer ID is shown, generate any App Store Connect API key once under Integrations → App Store Connect API. The name and access level do not matter. The Issuer ID is a single team-wide value, and it appears on both tabs once that key exists.
Download the .p8 file
Click Download Key to save the .p8 private key, then upload that file to the P8 key
file field in Voidhash.
Apple lets you download each private key a single time. Store it somewhere safe. If you lose it, you need to revoke the key and generate a new one.
