Important Rules

Important Rules

• Release notes are version-specific. Always match the documented behavior to the installed SDK version.
• Do not assume older projects use the latest request or response shape.
• Price-format changes matter operationally. In newer SDK versions, prices and many monetary fields are represented as integer paise.
• Check release notes before relying on newly added realtime streams, portfolio response versions, or trading request shapes.
