Hi @pradilla, I’ve asked about using axios in the Function node in the past but the team was hesitant to allow this. So I am afraid your code won’t work on n8n cloud 
You could try using request-promise-native which is currently whitelisted on n8n cloud, though this will eventually be removed from n8n altogether from my understanding. So your best bet would be to use a self-hosted version of n8n for the time being, and also leave a vote on the corresponding feature request.
