Evidence boundary: Atlassian Marketplace continues. The removed surface is the V2 API family.
What changes
Marketplace integrations can no longer rely on V2 endpoints and must use the supported V3 API contracts.
Who is affected
- Marketplace vendors with automation calling V2 endpoints.
- Internal reporting or catalogue tools built around V2 response shapes.
- Libraries, scripts and CI jobs that did not complete the V3 migration.
Timeline
V2 endpoints were switched off on 30 June 2026.
Required action
- Identify all V2 calls and map them to V3 equivalents.
- Update request paths, authentication assumptions and response parsing.
- Retest publishing, reporting and catalogue workflows.
What is not affected
The Marketplace product and supported V3 APIs remain available.
PlatformTrace analysis
This is a completed API removal: applications that missed the migration window require code changes before normal operation can resume.
