Editing Help:Link (section)

=== From a page ===
To report links ''from'' a page, you simply list all the wikilinks on that page.
* {{slink|Wikipedia:Tools/Editing tools|Relink}} can count wikilinks from a copy of the wikitext on your local machine.
* Some [[Wikipedia:text editor support|text editors support]] the counting and highlighting of the <code>[<nowiki/>[...]]</code> pattern occurrences.
* The Wikipedia [[Application programming interface#Web APIs|web API]] accepts queries by URL.<ref>
If you will use the API heavily or professionally you should follow its currently listed recommendations at [[mw:API:Query|API]].
(Use <kbd>continue=</kbd>, use <kbd>formatversion2</kbd>, use multiple pages at once, etc.)</ref>
One way to send a query to the API is by creating an external link ({{slink||External links}}).
For example, using an external link very much like a search link, you can
send the API a request to list the link properties of "[[wp:example]]".
It should interpret it correctly as "Wikipedia:Example", ''pageid 25263910''.
; What you type
:<kbd>[/<nowiki/>/en.wikipedia.org/w/api.php?action=query&prop=links&pllimit=500&titles=''fullpagename'' ''your label'']</kbd>
; What you get when fullpagename is [[wp:example]]
:[//en.wikipedia.org/w/api.php?action=query&prop=links&pllimit=500&titles=wp:example ''your label'']
* The report is in [[JSON]] format, as is usual for RESTful APIs.
* The pageid is available from '''Page information''' on every page.
* The <kbd>titles</kbd> parameter is plural. (It is designed to take multiple fullpagenames or pageid, delimited by the | pipe character.)
* The number of links returned by this query is limited to 500, per the URL you created. See [[mw:API:Query]] for how to safely get more. For example, [[Operating system]] has 510 wikilinks.

To make a page register as a link to a page, but without actually showing the link,
make a link to it, but label it with a space character using the pipe trick: <kbd>[<nowiki/>[''pagename''|&nbsp;]]</kbd>.
