Hi Arihant J., great question. I'm Byron, Head of Platform, and my team works on the API and MCP.
Gamma 5 has dedicated generation endpoints you can move to, and your existing Classic integration can keep running while you test. The main changes are the request body, polling endpoint and result parsing. You can still request PPTX export.
Here's a new page in our dev docs that might help you and your agent do the migration.
