Update tenant app version by ID

Updates the description field on a specific tenant app version.

This is a narrow update endpoint; the only writable field is description, so it's used for annotating a version rather than changing its binary or platform.

About Update Tenant App Version

⚠️ iOS and Windows only. Because the app binary itself is immutable once uploaded, this endpoint only supports updating the version's description. To change the actual app content, upload a new version through POST /v2/tenant-apps instead.

Key Fields / Request Body

description — the only writable field on this endpoint

Common Use Cases

Adding release notes or context to an already-uploaded version

Correcting a typo in a version's description after upload

Best Practices

Do not expect this endpoint to change anything beyond description, including platform or the app binary

Workflow

Obtain the appId and versionId for the version you want to annotate

PUT the updated description to this endpoint

Confirm the change with a follow-up GET on the version detail
