To connect your exchange account to J'JO you will need to enter your Public API key and Secret API key.
To get them, you will need to set up new API keys on the exchange website.
If you already have created API keys in your exchange account, you will not be able to connect to J'JO. The "Secret API Key" is only shown once, immediately after creation, and becomes unavailable for viewing in the future.
The J'JO team has prepared instructions for connecting each exchange. You can easily find them on the connection page of the selected exchange in your J'JO personal account.
