Successors mark the article that replaces a discontinued one (source_article_number → successor_article_number). Pushing them lets Mercura retarget demand for a phased-out article onto its current replacement.
You can:
POST /articles/successors— bulk-upsert up to 100,000 successor links in a single call. Async — returns aJobAck; pollGET /jobs/{job_id}for status.GET /articles/successors— cursor-paginated list of your successor links. Passsource_article_numberto look up one article's successor, ormodified_sinceon the first page to fetch only what changed.
A source article has exactly one active successor. Re-sending a source article with a different successor_article_number replaces the previous successor — this is the intended way to update a chain. order is accepted for parity with the other relations but has no effect on a 1:1 link.
