The third component is the title. Depending on what you are citing, your title will be formatted differently.
Author. (Date). Title OR Title. Source.
Sources: Publication Manual, 9.18-9.22; APA Style: Elements of Reference List Entries; APA Style: Missing Reference Information
APA requires you to only capitalize certain words in a title. You should capitalize the following:
APA requires you to italicize the titles of stand-alone works:
If you are citing something that is part of a bigger work, you do not italicize the titles:
If a title ends with a non-period punctuation mark (such as a question mark or an exclamation mark), use that as the ending punctuation without adding a period.

If the title uses an em dash instead of colons for a subtitle distinction, preserve those.

(Jain et al., 2004)
If the information you are citing is not a routine format, use square brackets after the title to clarify. Common examples include:

(Crash Course, 2017)
For some books, you will need to add the edition or the volume used after the title, in parentheses.

In very rare cases, you may be using a source without a specific title. This may be something like a social media post, untitled artwork, or a Google map. In the title component, include a description in brackets; try to include the medium in the description if possible.
