This is a full replacement, not a partial merge: every mutable field is written from the request, so a field you omit is set to null. Send the complete record, not just the fields you are changing.
The same validation as CreateClient applies, and clientInvoiceType is again the invoice type name rather than an id. A lookup id that does not exist returns 400.
A lead id returns 404 — leads are updated through UpdateLead. A client id belonging to another agency, or under a branch the Recruso user behind your API app cannot access, also returns 404. branchId must be a branch that user can access: moving a client to any other branch returns 400, not 403.
modifiedBy and modifiedOn are set from your credentials and the current UK local time; they are not taken from the request.
Access. Requires a client-credentials access token. Tokens issued through the interactive user login are rejected.
