Linked Keys

Link child keys to a parent key

Designates a translation key as a parent and links one or more child keys to it. Once linked, child keys receive a special reference marker as their translation content, signalling that their translations are derived from the parent. Use this when you want to group related keys — for example, a short label and its long-form variant — so translators see them in context together.

Pass an empty child_key_ids array to mark the key as a parent without linking any children yet. Both the parent key and every child key must belong to the main project; branch keys cannot participate in key links. A child key can have at most one parent at a time; attempting to link a child that already has a parent returns a 422 error with code CHILD_IS_ALREADY_LINKED. Parent and child key plurality must match — linking a plural child to a non-plural parent (or vice versa) also returns a 422.
