GET request

edit
List distinct links (i.e. no duplicates) which point to the main namespace.

Possible errors

edit
Code Info
badcontinue Invalid continue param. You should pass the original value returned by the previous query.
invalidparammix The alprop=ids parameter cannot be used with alunique.
This happens when you use alprop=ids and alunique together

Additional notes

edit
  • As with other link modules within the Action API , this module returns the titles of the pages that link to the namespace, not the exact URIs to those pages.
  • This module can be used as a generator.
  • Previous versions would return an error if the user tried to run this module as a generator, and alunique was set to true. This was altered in v1.24, to allow using the module as a generator even if alunique is true.
