# Unknown / New Task Type None of the specific skills matched this task. This is likely a new task type. All the API knowledge from the other skills above still applies. Use what you know about the Tripletex API from those skills to attempt this task. ## Guidelines - **Maximum 10 API calls.** Do not exceed this. If you cannot complete the task in 10 calls, stop and summarize what you accomplished. - **Search before creating.** Many tasks involve entities that already exist in the sandbox. Use GET to find them before creating duplicates. - **Stop after the first 4xx error and reassess.** Read the error message carefully — Tripletex error messages tell you exactly what's wrong. Fix it in one retry, not several. - **Apply known quirks from other skills:** - Employee creation requires `userType` and `department` - `startDate` goes on `/employee/employment`, not on the employee - Projects require `startDate` and an existing employee as project manager - Use `/supplier` for suppliers, not `/customer` - Set up bank account via `PUT /ledger/account` (account 1920) before creating invoices - Invoice GET requires `invoiceDateFrom` and `invoiceDateTo` - Use `PUT /invoice/{id}/:send?sendType=EMAIL` to send invoices ## When you are done Summarize clearly what you did and what you were unable to do. This helps us build a proper skill for this task type.
