SetPostTranslationsInput

This is an ID that can be passed to a mutation by the client to track the progress of mutations and catch possible duplicate mutation submissions.

When true, replace the existing translation group with the input map (Polylang default). When false or omitted, the input is merged into any existing group so previously-linked siblings are preserved.

Two or more language-keyed post IDs that should be linked. The source post must be included.
