I'm not very strong with http and urlfetch, but I'm trying to log in to my TD-Ameritrade account with urlfetch here is the API description: How do I pass the parameters and how do call urlfetch? what is a content type http header?
There maybe an issue with the documentation.
From local documentation "BodyData" is there and works. The link in the previous post does say "Wolfram Language"?
Thanks, that worked! Exactly what I was looking for. Where did you find the BodyData option?
