Title of web page in sentence case. (n.d.). In Title of website or dictionary/encyclopedia in italics. Retrieved from http://website.ca/full

Formatted example:

For more help citing websites, see this chart from the official APA website. 

There are two options for citing this source in-text:

1) Title of the entry in mixed case and quotation marks, publication date, and the page number(s) are placed in brackets at the end of the sentence. When there is no date, use (n.d.). When there are no page numbers, refer to the paragraph number or heading within the text:

("Crowdsourcing," n.d., para. 1).

2) Alternatively, the citation may be integrated into the sentence with a signal phrase and narrative. If lengthy, abbreviate the organization or group name:

"Crowdsourcing" (n.d.) is defined as a process of "obtaining needed services, ideas or content by soliciting contributions from a large group of people and especially from the online community" (para. 1).
