Mollie sales invoice creation, listing, retrieval, updates, and deletion. This feature pack is generated from the complete OpenAPI 3.1 document embedded in Mollie’s official create-sales-invoice reference page and hash-locked in the generated audit fixture as 09254cb73aea39a7c0134c8d1ce0755929d8a32c35c73049329bc4e32bf74668. The installed family carries 124 catalog operations covering 124 of 143 unique official routes with 19 exact fail-closed exclusions. New reads are uncached, mutations are grant-off and approval-gated, every new POST requires a caller-owned Idempotency-Key, JSON inputs are bounded, and unsafe response integers remain exact strings. Beta capabilities retain an explicit warning. No financial or control-plane object is misrepresented as a task, note, or project Source.
