Hi dears,
i'm testing the sandbox, and the hello world is working find with me, when I try to do the card on file API call I'm getting the below error.
Hi @moneerqh,
COF API requires MLE (Message Level Encryption). Please encrypt your request payload and decrypt the response with the correct MLE credentials. Please navigate to the link below for the MLE guide.

Hope this helps, please let us know if you have any questions.
Thank you, it's clear now.
i couldn't find the "Get the Postman MLE Zip File". and tried to search for it on the web but couldn't find it!
found it in the Assets thank you.
