Are API-created contacts exactly the same as UI-created ones?

Yes contextually. When you execute the `create_contact` function natively alongside `category` parameters (`3` stands for customer, `4` for typical suppliers), sevDesk anchors these entries officially inside the identical primary table. Be clear about whether it's an email-lead versus a firm.

Wait, does my generated API Token expire if left unused?

No. The verified 32-character hexadecimal key token possesses an infinite lifeline inherently tied directly, securely, and stubbornly to your primary login account. It decays or dies primarily upon deliberate manual revocation (regeneration) directly executed by you inside your dashboard user settings.

Can I fetch detailed line items from a single invoice ID using this agent?

Absolutely. Querying `list_invoices` outputs high-level paginated arrays, but invoking the precision extractor `get_invoice` fed deliberately with a target identifier ID unveils the core metadata array detailing isolated tax mappings, due-date boundaries, and intricate line items.
