updateRegister

mutation · in the family Register

What it does

Edit a register — one till position a device drives — change its details.

Edit a Register's mutable attributes. Requires the unrestricted capability + the record's CURRENT revision.

Careful

Edits take effect immediately and write a new revision; the old revision stays in history.

Who may call it

An API key whose scope allows api:updateRegister

Arguments

Name	Type	Required	Notes
`id`	ID `ID!`	yes	The id of the record.
`revision`	ID `ID!`	yes	The revision id you read on the record; the change is refused if an edit landed in the meantime.
`input`	EditRegisterInput `EditRegisterInput!`	yes	No further notes.

Returns

Register Register! — A Register — a POS terminal / till position at a LogicalFacility: the LOGICAL till identity TillSessions parent to (physical device pairing =, one-way Device→Register — never stored here). The OPERATIONAL lifecycle verbatim. The gate: a LIVE TillSession (open/suspended/counting) blocks deactivate AND doom, CONFLICT/REFERENCED naming it; terminal sessions never block.

Dry run

Add dryRun: true to the request envelope (extensions.at) to rehearse this call: every check runs, the write is rehearsed against the current records and nothing is stored; the answer is the refusal a real call would give, or the record it would create. Every response to a rehearsal carries dryRun: true, so a rehearsed record is never mistaken for a saved one.
