Serve the complete JSON representation advertised as a resource's WebSub topic.<\/p>\n

The websub_topic<\/code> dispatch is \/.zotonic\/websub\/topic\/:id<\/code> and supports GET and\nHEAD. It offers only application\/json<\/code>, independently of the representations\navailable through the semantic \/id<\/code> URI. The export uses the x-default<\/code> language\ncontext, avoiding a language-dependent delivery topic.<\/p>\n

Successful responses use the resource-export envelope:<\/p>\n

{"status":"ok","result":{"uri":"https:\/\/example.com\/id\/123","resource":{}}}\n<\/code><\/pre>\n
The example abbreviates the result; m_rsc_export:full\/2<\/code> supplies the complete\nexport, including connections, media metadata, and discovery links. The resource's\nresult.uri<\/code> remains its language-less semantic identifier. The HTTP Link self\npoints to this JSON topic, and the hub link identifies controller_websub<\/code>.<\/p>\n
Only authoritative local resources are served. Export access uses the current\nrequest's ACL context; an export error returns 403, while a missing or\nnon-authoritative resource returns 404. Successful responses disable caching and\ninclude resource discovery headers. Private exports require authorized access.<\/p>\n
m_websub<\/code> uses the same full-export representation for delivery to verified\nsubscribers, including non-Zotonic subscribers. See mod_websub<\/code> for discovery,\nsubscription, and the distinction between resource identity and delivery topic.<\/p>","slug":"controller_websub_topic","is_protected":false,"visible_for":0,"tz":"UTC","language":["en"],"doc_source_hash":"00eb9352b95095aee4a9dc2a285898472b4bfeaa8f3ff4b77cfec719dd24e761","is_featured":false,"content_group_id":{"id":2551,"is_a":["meta","content_group"],"name":"content_group_imported_docs","title":"Imported documentation","uri":"https:\/\/zotonic.com\/id\/content_group_imported_docs"},"category_id":{"id":321,"is_a":["meta","category"],"name":"controller","title":"Controllers","uri":"https:\/\/test.zotonic.com\/id\/321"},"doc_source_path":"apps\/zotonic_mod_websub\/src\/controllers\/controller_websub_topic.erl","publication_start":"2026-09-29T13:07:43Z","github_url":"https:\/\/github.com\/zotonic\/zotonic\/blob\/master\/apps\/zotonic_mod_websub\/src\/controllers\/controller_websub_topic.erl","pivot_location_lng":null,"doc_source_kind":"controller","name":"doc_controller_controller_websub_topic","is_unfindable":false,"is_published":true,"pivot_geocode":null,"created":"2026-09-29T13:07:43Z","uri":null,"doc_status":"current","is_dependent":false,"erlang_app":"zotonic_mod_websub","publication_end":"9999-06-01T00:00:00Z","modifier_id":{"id":1,"is_a":["person"],"name":"administrator","title":"Site Administrator","uri":"https:\/\/zotonic.com\/id\/1"},"privacy":0,"doc_source_commit":"85498256abd162b9bc082d43a90c995844fd4408\n","erlang_module":"controller_websub_topic","creator_id":{"id":1,"is_a":["person"],"name":"administrator","title":"Site Administrator","uri":"https:\/\/zotonic.com\/id\/1"},"modified":"2026-09-29T14:40:15Z","title_slug":"controller_websub_topic"},"uri":"https:\/\/zotonic.com\/id\/2709","uri_template":"https:\/\/zotonic.com\/id\/:id","websub":{"hub":"https:\/\/zotonic.com\/.zotonic\/websub","topic":"https:\/\/zotonic.com\/.zotonic\/websub\/topic\/2709"}},"status":"ok"}
