In your Conekta Admin you can find your API Keys.
Copy and use the private production mode key. Remember that it is very important to use the private production key, once you switch to production mode. If you continue to use the sandbox private key, all payments will be fake and you will not receive deposits from Conekta
Return to the SpinCommerce Admin (Preferences → Payment methods).
Locate the Conekta module and paste your production keys in the corresponding fields. When you are done click "Save".
