ExTda
ExTda helps Elixir users use the TDAmeritrade API.
To use this, set the TDA_CLIENT_ID
environment variable to your developer Client ID. .envrc.example
is an example file that, once renamed to just .envrc
, can be used with direnv.
To get your developer Client ID sign in at https://developer.tdameritrade.com with your TDAmeritrade brokerage account and go to the My Apps
tab. Create an app with the callback url of https://127.0.0.1:4000
. The Client ID here is what you need.
To use ExTda, make sure .envrc
is updated with your Client ID, and generate self-signed certificates for a local https server in the root directory:
openssl req -newkey rsa:4096 -x509 -sha256 -days 365 -nodes -out localhost.crt -keyout localhost.key
Finally, use iex -S mix
to start up an elixir repl, which also starts a local https server on port 4000. Visit https://12.0.0.1:4000
and TDAmeritrade should ask you to log in. Log in with your brokerage account, allow the permissions warning, and you will be redirected back to https://12.0.0.1:4000?code=...
which should do the rest for you. At this point the rest of the functions in module ExTda.Client
should work. You can run ExTda.Client.get_access_token/0
which, if you get a token, means things are working. In order to get a token from that the refresh_token
must be valid.
