I tried https://api.stackexchange.com/2.3/users/MY USER ID/timeline?sort=creation&page=1&pagesize=100&site=stackoverflow
, then https://api.stackexchange.com/2.3/users/MY USER ID/timeline?sort=creation&page=2&pagesize=100&site=stackoverflow
and continued to do the same requests incrementing page numbers until the API got to the last smaller page of data. I got an array called "items" that contained all of my questions, comments, answers, etc... but no body text.
I figured maybe if I requested "questions" individually it would give me the body text and then I could repeat this process for answers and comments. I ran https://api.stackexchange.com/2.3/questions/QUESTION ID 1;QUESTION ID 2;QUESTION ID 3;MORE QUESTION IDS SEPARATED BY SEMI COLONS ETC...?site=stackoverflow
and the result still didn't have body text.
So how can I do a query that actually gives me the body text of my questions, answers, and/or comments?
