Every change to a model, battery, passport, document or registration is written to an audit trail with a hash of the record before and after. This is the "who, when, from which source" record (Art. 78(g)), readable over the API.
Personalise the samples. Paste a test key and every snippet uses it — and your own model and passport ids.
/v1/auditList audit entries
Audit entries for your organisation, newest first, a page at a time. Each holds the SHA-256 of the record before and after the change, so you can prove what a record looked like. Changes made over the API are attributed to the member who created the key.
