It is important you setup a new API key/secret pair for leonArdo. On most exchanges you can do this by going to the settings/security sections of their websites. Then you need to create a new API key/secret pair.
Let’s take a look at an example on Bittrex. After clicking the ‘Add New Key’ button and entering my 2FA code a new key is generated.
You should immediately save your secret as on many exchanges it is only shown once. We only need at least the first half of your secret so in this example the following would be enough
3a2aee8966474b59a1
This needs to be added to your margin account here: Manage exchanges
Note that all options, except for withdrawal rights, should be checked.
To login at the exchange later please save the full key and the full secret.
On each exchange the procedure is basically the same, but don’t hesitate to get in touch with us if you need any assistance!
