Edit Action Not Working
Dear early adopters, does the edit action work for anyone? I try hard but can't get it to work with an php client. Like suggested at the login-discussion site i now use the Snoopy library to set the cookies for the mw system (hopefully this is not necessary anymore in the near future!). I am able to login and to request a edit-token. but if i try to edit the content, i get the result Conflict detected. Is it possible to get some more details about the conflict? Any logfiles or something else which could help?
 * Ah, found the conflict myself: i was using the false epedittime. Now it works!

Create pages
How do I need to change the code in order to create, rather than edit, a page? Thanks.

Sorry for the late response. Create and edit are the same from the API point of view. eptext=WikiText parameter is the whole article content, including changes when the article has been edited, or new content when eptitle did not exist. --Raquel.Frisa 10:07, 19 October 2007 (UTC)


 * one little difference would be useful: sometimes you want to change an article only if it exists, but not create it if it doesn't. an example: inserting a speedy-deletion-template should not recreate an already deleted article. -- ∂ 01:48, 21 October 2007 (UTC)
 * What about you just check for the article's existence using api.php?action=query&prop=info&titles=hddfal? --Catrope 12:26, 21 October 2007 (UTC)
 * Race condition -- ∂ 15:03, 25 October 2007 (UTC)
 * You'll get an w:Wikipedia:Edit conflict, won't you? --Catrope 22:16, 30 October 2007 (UTC)
 * that would only be possible if i fetched the edittoken before the article has been deleted, and there's no way to ensure that. -- ∂ 13:35, 5 November 2007 (UTC)
 * True. There should probably be an epNoCreate parameter. --Catrope 15:08, 5 November 2007 (UTC)

Can't pass &prop via php

 * That's weird. You could:
 * Try to use &amp; rather than &
 * Use Snoopy, which doesn't have this problem (and allows you to specify post data as an array instead).
 * --Catrope 14:25, 13 November 2007 (UTC)

Odd - is this enabled?
Maybe I'm missing something -- heck, I probably am :)

Say, I try a request like this:

deadline to enable action=edit on Wikipedia?
If not soon, what method you'd suggest to use meanwhile? -- Григор Гачев 09:20, 14 August 2008 (UTC)
 * I don't think action=edit will be enabled on WMF wikis very soon. To make action=edit cooperate nicely with extensions, a rewrite of EditPage.php should really be done. I've done some of that rewriting already, but it'll take some time. In the meantime, you can use pywikipediabot. --Catrope 12:41, 15 August 2008 (UTC)

internal server error using edit
I´m trying to edit an article on en.wikipedia.org. The response I´m getting from the server seems ok when it returns a code error, like "cantcreate-anon" if the query doesn´t identify the user, "articleexists" if it is trying to create a page that already exists and the createonly parameter is set or "badtoken" if the token is not valid

But when the request seems to be all right I get an Internal Server Error (Http code 500).
 * This was fixed, see also 15420. --Catrope 21:20, 6 September 2008 (UTC)

Strange stuff ?
I've some problems using this editing API: Is there any info about this comportement, do I fortget someting ? I use Mediawiki 1.13.1. Charles 16:39, 5 October 2008 (UTC)
 * All parameters must be send in the url to be understand by the server, but I must use a POST request and fill the content with some dummy data. (why not passing the content of my page in the post?)
 * And the token is not received properly : the final caracter + is replaced with a space, and the token test fails.
 * You should urlencode the token so the  is encoded as  . Also, you shouldn't put dummy data in the POST body; instead, you should set the Content-Type to   and use the query string (e.g.   as the POST body. --Catrope 20:26, 5 October 2008 (UTC)
 * Ok for the urlencode. Stupid question, trivial answer... :-p
 * For the post problem, that's really strange. It works perfectly if I send a POST and send ma datas in the URL... Setting Content-Type to application/x-www-urlencoded changes nothing. URL's length is limited, so I have to fix it. If anybody have a suggestion? Charles 20:14, 6 October 2008 (UTC)
 * Ok, found. you must set content type to application/x-www-form-urlencoded (do not forget the form !). Thnak you for your help! Charles 20:20, 6 October 2008 (UTC)

token clarification
currently, the code for getting an edit token is given as follows:
 * api.php?action=query&prop=info|revisions&intoken=edit&titles=Main%20Page

this raises a question about the use of combined queries like '&prop=info|revisions'. how far can that be extended? is it restricted within general categories, or could we (if it made sense) do, say, a 'prop' and a 'list' command in the same query?

I think for the purposes of the documentation that we should drop the '|revisions' bit, which isn't necessary to get the token and last revision. I'll go ahead and edit that change in (feel free to revert if there's something I'm misunderstanding).

actually, I think there ought to be a 'API Programming Conventions' page that lays out some of these obscure details (like using a vertical bar to separate multiple options or actions, or sending combined requests). maybe combine it with the Formats page? --Ludwigs2 20:23, 14 October 2008 (UTC)
 * Stuff like  can be extended as far as you want, although duplicate values will be ignored. Combining ,   and even   in one request is also allowed. In short: in an   request, you can use any combination of query modules.
 * As I explained in my edit summary,  is not redundant, you need it to get the last revision's timestamp, which may be different from.
 * I thought using the pipe for multivalue parameters was documented somewhere, I'll check and add it if it isn't. I'll also add a note about combining query modules if there isn't one already. --Catrope 14:19, 15 October 2008 (UTC)


 * ah, ok, that makes sense. and thanks for adding the note.  :-)

Don't watch ?
Hi,

Is there an option for not modifying your watchlist, even though you have a preference like "Automatically watch all pages I edit" enabled ? The options available on the documentation are listed below. I was looking for something like the  but without "Remove".


 * : Add the page to your watchlist
 * : Remove the page from your watchlist, or don't add it even though you have a preference like "Automatically watch all pages I edit" enabled

--NicoV 10:26, 18 October 2008 (UTC)
 * No, there is no such option. I guess we kind of expect people to know whether they're watching a page and what their preferences are. --Catrope 21:00, 19 October 2008 (UTC)


 * Thanks for the answer, but when you're editing pages on Wikipedia, the effect of this option is simply to check by default the "Watch this page" checkbox, so the user still has the choice of watching or not the page. When using the API, there's no easy way (or at least, it requires other requests) to know if the edited page is watched or not. What is strange for some users is that they think this setting is only used when directly editing (where they can choose for each edit), not when they are using a tool. --NicoV 16:12, 20 October 2008 (UTC)
 * You're right that the UI supports this option in a way; I'll investigate how hard it would be to add such an option. --Catrope 15:25, 21 October 2008 (UTC)
 * Oh wait, it doesn't. I confused the option not to change one's watchlist (which is what you want) with the option to do what the UI does by default (if you don't explicitly specify whether to watch or unwatch a page, don't change the watchlist unless your preferences say otherwise). About the confusion issue: tools making edits could simply provide a ternary choice like:
 * Watch this page
 * Don't watch this page and unwatch it if I'm already watching it
 * Only watch this page if I'm already watching it or if my preferences say to watch it (neither  nor  )
 * which should be fairly clear. --Catrope 17:52, 21 October 2008 (UTC)

About the ternary choice, it's possible but far from perfect is some situations even for edits page by page. In my own case, my own tool is a maintenance tool for small edits on a lot of pages, keeping the watchlist unchanged seems the better default option. And also, when you're doing changes in batch, this choice is not really possible because the answer could be different for each page. Thanks for the answers :) --NicoV 19:16, 21 October 2008 (UTC)

How to get the section numbers of sections?
To edit a specific section I need the section number of that section. Can anybody tell me how to get the section numbers for the sections on a page?

I tried to use:

but then I get number 1 for the first section, 1.1 for a subsection and so on. I need numbers like 1, 2, 3, and so on. No matter if section or subsection. Any clues?
 * Those numbers are sequential, so you can just count 1, 2, 3, ... from the top down. The fact that this doesn't work with sections transcluded from templates is a known bug. --Catrope 14:27, 11 February 2009 (UTC)

pagedeleted error
Hi,

It seems that there's a bug with some pages that have been deleted and restaured after that, but without any more modification. For example, on the French wiki, I get the error when trying to edit fr:Charbonnage. The page exists, its last version was one 2010-03-11 at 12:37:19, but it was deleted and recreated later this day (at 17:45).

Request made: http://fr.wikipedia.org/w/api.php?summary=WikiCleaner 0.99 - Correction des liens vers les pages d'homonymie&title=Charbonnage&text=...&basetimestamp=2010-03-11T12:37:19Z&token=xxxxxx+\&minor=&bot=&action=edit&format=xml

action=edit 'bot' parameter
The text of the manual reads:
 * bot: If set, mark the edit as bot, even if you are using a bot account the edits will not be marked unless you set this flag

What if you set this parameter for a non-bot account? Why do bot accounts have to set this flag at all? Cheers, --Dmb 22:40, 28 January 2011 (UTC)
 * As far as I know, nothing happens if you set the parameter for a normal account. For a bot account, the parameter has to be set so that if a person does a manual edit with the bot account (like answering on a talk page), this edit is not marked as a bot edit.

text from a file
Does anybody know how can I upload text from a file for a particular section? Thanks. Never mind I got it..I used `cat filename` instead of text I need help in this again, I am trying to execute the curl unix command from java and it does not accept `cat filename`. Anybody has a clue?

Appending text to a section
Is there a way to append the content of a section. This api deletes the existing section and replaces it with the supplied text.


 * I would retrieve sections contents ... Append to the string with my programming language and replace the sections contents with the result.


 * You can use the  and   parameters:

prependtext   - Add this text to the beginning of the page. Overrides text. appendtext    - Add this text to the end of the page. Overrides text
 * Hope that helped. --Ianmartorell 21:05, 27 August 2011 (UTC)


 * I found that appendtext didn't do what I wanted, somehow duplicating the entire page instead of just appending text to the section. My install's API docs say this about prependtext: "Don't use together with section: that won't do what you expect". I was forced to go the route of getting the section text, appending the new text, and setting it back. -- 193.119.19.197 16:18, 30 March 2012 (UTC)

captchaid and captchaword
I don't see captchaid and captchaword anywhere in the current ApiEditPage.php. Are those still parameters? Thanks, Leucosticte (talk) 03:33, 25 February 2014 (UTC)


 * It looks like those were moved to ConfirmEdit/Captcha.php as of 1.18. They appear in both places in 1.18.3 (and probably other 1.18s, that's just the one I have), then in 1.19 and onwards, they're only in Captcha.php. So, they still get emitted, it's just that the responsibility for them is handed off to the ConfirmEdit extension. Each module appears to have the ability to customize what gets output. For example, ReCaptcha.class.php appears to use recaptcha_challenge_field and recaptcha_response_field. – RobinHood70 talk 02:12, 26 February 2014 (UTC)

Null edit ?
Hi, is there a simple way to do a null edit without sending the current page contents ?

For my need, I'm not sure a simple purge will work. The problem is with the automatic categorization of pages using duplicate arguments in template calls (example on enwiki). If I fix a page that is trancluded in other pages, the other pages are still appearing in the category. On the user interface, I tried purging the page (with the purge gadget available in the preferences) without success, but performing a null edit worked.

I'd like to do the same using the API, but it could be nice to avoid sending back the entire text. --NicoV (talk) 12:26, 20 April 2015 (UTC)


 * You can try just editing and saving section zero and see if that helps. Also, if you're on a new enough wiki (1.18+), try using purge with the  option rather than just a plain purge. I don't remember whether you want to do that on the page or on the template affected...I believe it'd be the page, but try both and see if either helps. As a last resort, on MW 1.22+, you can also try   on the affected template. That's much harder on the server, though, so don't use it unless it's really needed. – Robin Hood   (talk)  16:03, 20 April 2015 (UTC)

URL encoding of token
Going off the example, I have spent the past 20 minutes or so trying to figure out what was wrong with my edit code and why it was returning a badtoken error. As a sort of last resort, I removed the URL encoding of the +/ part of the token. Bam, as soon as I do this, the code works perfectly fine. Does the token need to be encoded or not?


 * It should. Is it possible that whatever method you're using takes care of the URL encoding for you automatically, so it's being double-encoded? – Robin Hood  (talk)  02:06, 30 September 2015 (UTC)
 * From what I can see in httpclient.rb (from HTTPClient, the Ruby client that MediaWiki::Butt uses), it doesn't. But it might. I'm not 100% certain on what setting the content-type header to application/x-www-form-urlencoded does, but that might be what I'm looking for? I have no idea to be honest.

Edits randomly failing
I am adding large numbers of pages to my wiki via the Perl API. Some, maybe 5%, are creating pages that don't work correctly. Some are getting Lua error: Internal error: The interpreter exited with status 2 for the infoboxes and I've seen a few where a property is wrong. I can fix these in two ways: either edit the page via the GUI and click Save changes (without making any changes to the page), or by rerunning the Perl script to edit the page via the API (recreating the identical page).

This is with Mediawiki version 1.25.6, Semantic Mediawiki and the Perl Mediawiki::API.

Invalid CSRF token

Structured Data?
Is there a way to write structured data to a page, where some structured data already exists? Eg, CSV: Color, Info Blue, Like the sky Green, Like seaweed

i supposed one could simply write: Current text + newline + Purple, Like grapes but wondered if there was a more structured way.

The above example might work fine for new records, but not for editing existing records.

Using "Json" in the edit call might be the way. Any Json examples available? Thx Johnywhy (talk) 23:30, 26 May 2018 (UTC)

When i edit an existing section with javascript, the section title gets overwritten by the new text. sNewDescription = 'Hello, World.'; var api = new mediaWiki.Api; api.postWithToken( "edit", {       action: "edit",        title: "Portal:TagDescriptions",        section: iSectionID,        text: sNewDescription    } ).done( function( result, jqXHR ) {        alert( "Saved successfully" );        //location.reload;    } ).fail( function( code, result ) {        if ( code === "http" ) {            alert( "HTTP error: " + result.textStatus ); // result.xhr contains the jqXHR object        } else if ( code === "ok-but-empty" ) {            alert( "Got an empty response from the server" );        } else {            alert( "API error: " + code );        }

How to prevent?
