Grammar error

       In the first paragraph, "What is JSON Web Token?", change "an" to "a" before the word "URL." According to Ivy Wigmore, "Although the 'U' at the beginning of 'URL' is a vowel, the abbreviation is pronounced 'you-are-ell.' Because the letter 'Y' is a consonant in this case, use 'a' rather than 'an.'" @url: http://itknowledgeexchange.techtarget.com/writing-for-business/which-is-correct-a-url-or-an-url/ 
Please apply this very basic grammatical logic when writing articles in the future.
