An APA citation uses endnotes. These are written as superscripts: smaller numbers that appear above the line of normal text.
For example,

Where should I put my endnotes?
Endnotes should be placed after periods and commas, and before colons and semicolons.
See examples below
At this point, the patient complained of headache.3

Ideas, facts, or passages of text that you found in a source all need to be cited.

or
Quotea source by using the author's exact words in your paper.
Either way you must give credit to the source you found the idea in!
If you want to use an idea but not quote it, you can restate it in your own words.
Make sure what you write is not too similar to the author's wording.
For example:
Jowers asserts that guard llamas are an effective way for a shepherd to protect sheep.2
Some argue that guard llamas are an effective tool in protecting a flock of sheep.2
Either way you need to place an endnote after the paraphrase.
If you use the author's exact words, you need to put them in quotation marks, and place your footnote after the quotation marks.
For example:
He stated, "Practitioners recognize these symptoms as characteristic of phlebitis."4
If you want to quote an entire paragraph or many sentences word for word, do a block quote. You do not need to use quotation marks in a block quote, but you do need to indent the entire quote.
Here is an example.
