How to insert DOI to APA output style?

I’m using Endnote 7th edition with APA 6th revised with no initials.  I need to include the DOI numbers in the bibliography. Could you please provide clear, step by step instructions? I’m working from rural Africa with intermittent internet. Thanks  

If you have a reference in your library that is a Journal Article, Electronic Article, Electronic Book or Electronic Book Section then DOI field will be included by default.

If you want to add DOI information to a reference you would double click on the reference then scroll down to the DOI field and enter in the information.

Here is a example reference.

Olry, R., & Haines, D. E. (2011). Renfield’s syndrome: a psychiatric illness drawn from Bram Stoker’s Dracula. J Hist Neurosci, 20(4), 368-371. doi:10.1080/0964704X.2011.595655

So in the DOI field you would enter 10.1080/0964704X.2011.595655

Here is the Clarivate site KB  link to the style editing documents in case you need to tweak any other templates.
