- url: URL of an online location where the text of the publication named by title can be found. Cannot be used if title is wikilinked. If applicable, the link may point to the specific page(s) referenced. Remove tracking parameters from URLs, e.g.
#ixzz2rBr3aO94or?utm_source=google&utm_medium=...&utm_term=...&utm_campaign=.... Do not link to any commercial booksellers, such as Amazon; use|isbn=or|oclc=to provide neutral search links for books. Invalid URLs, including those containing spaces, will result in an error message.- access-date: Full date when the content pointed to by url was last verified to support the text in the article; do not wikilink; requires url; use the same format as other access and archive dates in the citations.[date 1] Not required for linked documents that do not change. For example, access-date is required for online sources, such as personal websites, that do not have a publication date; see WP:CITEWEB. Access dates are not required for links to published research papers or published books. Note that access-date is the date that the URL was found to be working and to support the text being cited. See "Automatic date formatting" above for details about interaction with
{{use dmy dates}}and{{use mdy dates}}. Can be hidden or styled by registered editors. Alias: accessdate. - archive-url: The URL of an archived snapshot of a web page. Typically used to refer to services such as Internet Archive and archive.today ; requires archive-date and url. By default (overridden by
|url-status=live) the archived link is displayed first, with the original link at the end. Alias: archiveurl.- archive-date: Archive-service snapshot-date; preceded in display by default text "archived from the original on". Use the same format as other access and archive dates in the citations. This does not necessarily have to be the same format that was used for citing publication dates.[date 1] Do not wikilink; templated dates are discouraged. See "Automatic date formatting" above for details about interaction with
{{use dmy dates}}and{{use mdy dates}}. Alias: archivedate. - url-status: the
|url-status=parameter should only be included if an|archive-url=is set (dead links without an archive URL can be marked with {{Dead link}}). If|url-status=is omitted, or is specified with a null value, the default value is|url-status=dead. When the URL is still live, but pre-emptively archived, then set|url-status=live; this changes the display order, with the title retaining the original link and the archive linked at the end.
If the original URL is 'live' but no longer supports the article text, set|url-status=deviated. When the original URL has been usurped for the purposes of spam, advertising, or is otherwise unsuitable, setting|url-status=unfitor|url-status=usurpedsuppresses display of the original URL (but|url=and|archive-url=are still required). - archive-format: File format of the work referred to by archive-url; for example: PDF, DOC, or XLS; displayed in parentheses after the archive link. HTML is implied and should not be specified. File format annotation is automatically rendered when a PDF icon is displayed. Does not change the external link icon. Note: External link icons do not include alt text; thus, they do not add file format information for the visually impaired.

- format: File format of the work referred to by url; for example: PDF, DOC, or XLS; displayed in parentheses after title. (For media format, use type.) HTML is implied and should not be specified.

URLs must begin with a supported URI scheme. http:// and https:// will be supported by all browsers; however, ftp://, gopher://, irc://, ircs://, mailto: and news: may require a plug-in or an external application and should normally be avoided. IPv6 host-names are currently not supported.
If URLs in citation template parameters contain certain characters, then they will not display and link correctly. Those characters need to be percent-encoded. For example, a space must be replaced by %20. To encode the URL, replace the following characters with:
| Character | space | " | ' | < | > | [ | ] | { | | | } |
|---|---|---|---|---|---|---|---|---|---|---|
| Encoding | %20 | %22 | %27 | %3C | %3E | %5B | %5D | %7B | %7C | %7D |
Single apostrophes do not need to be encoded; however, unencoded multiples will be parsed as italic or bold markup. Single curly closing braces also do not need to be encoded; however, an unencoded pair will be parsed as the double closing braces for the template transclusion.
