How to Authenticate with TD Ameritrade API to get the AUTH code for local trading apps

As I am learning about automating my options trading, one possible method would be to use TD Ameritrade’s API since I have an account with them and like the Think-or-Swim platform which would help me monitor trades with a familiar interface.

However, despite the official API documentation (which leaves a little to be desired) and this great post on Reddit with instructions, I still ran into problems.

So once I figured out what was going wrong I decided to make this video that shows how I did it (and automated a lot of it with Zapier) because there seem to be a lot of people with similar challenges as I faced.

Here’s how I did it. If you have any questions, feel free to leave a comment and I’ll do my best to help.
