Hi, yes, that's right. You have to use the api that is registered and linked to your wallet. If you have Gunbot Pro or Ultimate, you can add more apis. That way you can always add more apis yourself from the GUI. Remember to keep at least 1 working api linked, or you won't be able to add a new api again. If this is your case, you would need to contact your reseller to help you to swap your api.
