Adam vs manual tools

Tyms is the accounting platform. Adam is Tyms’ AI agent used on AI create tools (for example: “create invoice from a description”). Manual create/update tools talk to the Tyms API directly. For prompt tips when asking Adam to create records, the same idea as the Developer API applies: be specific about dates, amounts, contacts, and descriptions. See also AI Prompt Guidelines in the Documentation tab.
