generated from the schema

Requires human confirmation

Put this tool on your client's “ask before running” list. The annotations are hints that the server declares, not guarantees: do not decide the approval from destructiveHint alone.

Same mode contract as accessories: merge is deltas, replace deletes what is absent. Returns the full item, with alternativeIds as they now stand, the same projection as its GET.

Arguments

itemIdstringRequired

Item identifier.

Limits: min length 1

modestring

merge (default): operations are deltas and whatever you do not name is kept. replace: the list sent is the final list and everything absent IS DELETED.

Available options: merge, replace

operationsobject[]Required

Operations to apply. At least one.

Limits: min 1 items

Show child attributes

operations.alternativeIdstring

Existing alternative. Required to update or delete.

operations.actionstring

What to do. If omitted: with alternativeId it updates, without it it creates.

Available options: create, update, delete

operations.alternativeobjectRequired

Alternative data.

Show child attributes

operations.alternative.itemIdstringRequired

Item that serves as the alternative.

Limits: min length 1

operations.alternative.notesstring

When or why this alternative is valid.

Limits: max length 1000

idempotencyKeystring

Idempotency key chosen by the client (a UUID is recommended). Repeating the same key with the same arguments within 24 h returns the stored response without executing again; with different arguments it responds 422. It is the safe way to retry after a network failure.

Limits: min length 1, max length 255

ifMatchstring

Optimistic locking: the meta.etag you got from the detail read of this resource (or "*"). If the resource changed since, the call fails with 412 precondition_failed before writing anything; read it again and retry. Omit it to write unconditionally.

Limits: min length 1
