Hello Wikimedia REST API users!

As part of the RESTBase Sunsetting project https://phabricator.wikimedia.org/T262315, we are rerouting the lint endpoints in the Wikimedia REST API https://www.mediawiki.org/wiki/Wikimedia_REST_API through MediaWiki. Both page and transform lint endpoints are affected. This change is expected to be seamless and non-breaking. However, because this work involves a service change, we would like your help to ensure that no tools, bots, or other integrations relying on these endpoints are negatively impacted.

*==== Impacted endpoints ====* Lint endpoints offered by the Wikimedia REST API https://en.wikipedia.org/api/rest_v1/ (under the /api/rest_v1/ path) are being rerouted. No other endpoints are affected. The specific endpoints are limited to:

GET /page/lint/{title}/ GET /page/lint/{title}/{revision}

POST /transform/wikitext/to/lint POST /transform/wikitext/to/lint/{title} POST /transform/wikitext/to/lint/{title}/{revision}

*==== Timeline & next steps ==== * The rerouted endpoints are currently live on test.wikipedia.org -- please feel free to test and verify functionality there at your earliest convenience.

Assuming no issues are observed or reported, we plan to utilize the following deployment schedule:

- *Tuesday, Oct 28*: Rerouting is live on test and test2 wikis. - *Monday, Nov 3*: Enable rerouting on Group 0 wikis. - *Tuesday, Nov 4*: Enable rerouting on Group 1 wikis. - *Thursday, Nov 6*: Enable rerouting on all remaining wikis.

*==== How to report issues ====* Please see T384216 https://phabricator.wikimedia.org/T384216 for more information, or to report any observed issues or changes in behavior related to this rerouting. You may also reply directly to this email, or file a new ticket to the MediaWiki Interfaces team board https://phabricator.wikimedia.org/project/view/6931/.

Thanks, Halley
