Possible errors that may appear during connecting or trading on the connected exchanges:
API key is invalid
API keys are no longer valid or incorrect
There is a problem with the connection. Please update your API connection.
Not enough permissions for API keys
Failed to generate API keys.
Please visit the API Management page on the Binance website.
Binance introduced a requirement that the first new API key created after 7th August 2023 on your account, will require you to visit Binance.com and accept a user agreement displayed on the API Management page.
Please accept the agreement and then link your account to 3Commas again.
This account is already connected
The exchange account that you are trying to connect is already connected to 3Commas. You can connect the same exchange account only once.
Exchange account is banned
Your account has been disabled from using the API
There may be a few reasons for this:
Please head to your exchange account and check if it is suspended for some reason. Also, you may need to contact the exchange's support.
If the conditions above are not applicable to your situation, please head to our status page to check if there is a general issue with API connection.
General information about API connection issues
Use the Fast Connect feature to update the API connection
If the exchange supports Fast Connect feature (Binance, OKX), update the API connection with it! Delete the old API keys on your exchange, and update the connection using Fast Connect (Reconnect) feature.
Here is an example of updating the Binance connection with Fast Connect.
Ensure exchange is available on 3Commas (just in case)
Similar names often represent different platforms.
Like Coinbase PRO and Coinbase, they are different exchanges.
Check available exchanges here.
Disable website translation
It often tries to translate API keys. Even one additional space makes keys invalid.
Use IP binding, whitelist, or restricted access everywhere it's required
Please make sure to input all the IP addresses that are shown on the exchange connecting window, which looks like this:
Select required permissions
When you create or edit API keys, you can choose what the key allows.
It varies across different exchanges, so it is better to check what permissions to enable on your exchange.
Copy keys fully and without extra characters
If the exchange provides a copy button near keys, use it.
Paste keys to a text editor, then compare with keys you see on the exchange. If they're different, select it more carefully or with a double click.
