• URL: URL of pmwiki.php or index.php
• Method: POST

• Body:

  action=edit&post=1&prepend=1&n=(page name)&text=<<<* '''{{ReceivedAt}}''' [[<<]] {{MessageNoHashtag}}>>>&authid=(username)&authpw=(password)
  
  

Additionally, pmwiki.php's HandleEdit function must be modified as such:

Using WordPress channel

This method is mainly of historical interest now that IFTTT has a proper webhook channel.

1. Text message sent to IFTTT
2. IFTTT recipe converts from SMS to a new WordPress post with the post title as the wiki page to edit and the following post body:
   
   

   * '''{{ReceivedAt}}''' [[<<]] {{MessageNoHashtag}}
   

   
   The hashtag in the SMS chooses which namespace.
3. IFTTT sends the WordPress post data to sms.sick.bike, a fake WordPress backend modified from ifttt-webhook
4. sms.sick.bike runs a request on pmwiki.php with all the appropriate fields (authid and authpw are taken from the WordPress login information from the channel on IFTTT) and an additional field prepend=1.
5. This method also requires the modifications to pmwiki.php as described above.
