AppVersion

A version of an app: the inputs its main takes, the tools it pins and its time limit.

Kind: an object, used in responses.

Fields

Every field is present in a response; empty ones are null.

Field	Type	Description
inputs	AppInput[]	The inputs this version takes: the parameters of its main, in order.
externalOperationsMcp	McpExternalOperationBinding[]	MCP tools pinned for the app’s code. Apps pin only OpenAPI tools, so this is empty.
externalOperationsOpenApi	OpenApiExternalOperationBinding[]	Tools the app’s code calls with ExtOpInvoke, each pinned to the version it had when the app was deployed (functions.openApi in the app’s .mtr file). A tool not listed is called at its latest version.
fileChecksum	base64	A checksum of the version’s compiled code. It changes when the code does.
executionTimeLimit	timespan | null	The longest a run of this version may take (duration.max), after which it is stopped with status Error. Null: no limit of its own.
credentialStack	string | null	The credential stack this version’s runs use, by id or name, when their start doesn’t name one (credentialStack in the app’s .mtr file). Null: the namespace’s default stack, then your tenant’s.
version	integer	The version number, from 1. Every change to a definition adds a new version with the next number.
date	datetime	When this version was created, in UTC.
isDisabled	boolean	Whether this version is disabled. A disabled version is never used: new links and runs take the latest enabled version, and anything pinned to this one fails until it is re-enabled.
