Response

Your app's own identifier for this installation, such as the ID of the linked account in another system, or null when none is set. At most 255 characters and unique across your app's installations, so you can find an installation with GET /app_installations?external_id=; setting one another installation already has returns a 409. Only the app and its developer see it; for the account the app is installed on it is always null.

"aag_xxxxxxxxxxxxxx"
String keys and values your app stores about this installation, such as a sync cursor or the ID of the linked account in another system. Empty until your app sets a key, and kept if the account removes the app and installs it again. At most 50 keys; keys are at most 100 characters and values at most 500. Only the app can change it. Only the app and its developer see it; for the account the app is installed on it is always null.
Whether the app now asks for permissions the account hasn't approved yet.
false
When the installation last changed, such as a metadata update or the account changing the app's permissions, as an ISO 8601 timestamp.
