Get revision information.

May be used in several ways:

  1. Get data about a set of pages (last revision), by setting titles or pageids.
  2. Get revisions for one given page, by using titles or pageids with start, end, or limit.
  3. Get data about a set of revisions by setting their IDs with revids.
Specific parameters:
Other general parameters are available.
rvprop

Which properties to get for each revision:

ids
The ID of the revision.
flags
Revision flags (minor).
timestamp
The timestamp of the revision.
user
User that made the revision. If the user has been revision deleted, a userhidden property will be returned.
userid
User ID of the revision creator. If the user has been revision deleted, a userhidden property will be returned.
size
Length (bytes) of the revision.
slotsize
Length (bytes) of each revision slot.
sha1
SHA-1 (base 16) of the revision. If the content has been revision deleted, a sha1hidden property will be returned.
slotsha1
SHA-1 (base 16) of each revision slot. If the content has been revision deleted, a sha1hidden property will be returned.
contentmodel
Content model ID of each revision slot.
comment
Comment by the user for the revision. If the comment has been revision deleted, a commenthidden property will be returned.
parsedcomment
Parsed comment by the user for the revision. If the comment has been revision deleted, a commenthidden property will be returned.
content
Content of each revision slot. If the content has been revision deleted, a texthidden property will be returned. For performance reasons, if this option is used, rvlimit is enforced to 50.
tags
Tags for the revision.
roles
List content slot roles that exist in the revision.
parsetree
Deprecated. Use action=expandtemplates or action=parse instead. The XML parse tree of revision content (requires content model wikitext). For performance reasons, if this option is used, rvlimit is enforced to 50.
Values (separate with | or alternative): comment, content, contentmodel, flags, ids, parsedcomment, roles, sha1, size, slotsha1, slotsize, tags, timestamp, user, userid, parsetree
Default: ids|timestamp|flags|comment|user
rvslots

Which revision slots to return data for, when slot-related properties are included in rvprops. If omitted, data from the main slot will be returned in a backwards-compatible format.

Values (separate with | or alternative): main
To specify all values, use *.
rvcontentformat-{slot}

Content serialization format used for output of content.

This is a templated parameter. When making the request, {slot} in the parameter's name should be replaced with values of rvslots.
One of the following values: application/json, application/octet-stream, application/unknown, application/x-binary, text/css, text/javascript, text/plain, text/unknown, text/x-wiki, unknown/unknown
rvlimit

Limit how many revisions will be returned. If rvprop=content, rvprop=parsetree, rvdiffto or rvdifftotext is used, the limit is 50. If rvparse is used, the limit is 1.

May only be used with a single page (mode #2).
Type: integer or max
The value must be between 1 and 500.
rvexpandtemplates
Deprecated.

Use action=expandtemplates instead. Expand templates in revision content (requires rvprop=content).

Type: boolean (details)
rvgeneratexml
Deprecated.

Use action=expandtemplates or action=parse instead. Generate XML parse tree for revision content (requires rvprop=content).

Type: boolean (details)

Type: boolean (details)
rvsection

Only retrieve the content of the section with this identifier.

rvdiffto
Deprecated.

Use action=compare instead. Revision ID to diff each revision to. Use prev, next and cur for the previous, next and current revision respectively. For performance reasons, if this option is used, rvlimit is enforced to 50.

rvdifftotext

  • When using parameters marked as (enum), titles= must have only one title listed.
  • This module couldn't be used as a generator prior to version 1.25.
  • Diff functionality of this module was deprecated in version 1.30 and got moved to API:Compare .
  • The code for this query is located on the git repository at ApiQueryRevisions.php.
