Based on my investigation and usage, it appears that Cardyfie’s API is actually utilizing upstream services from finup.io rather than operating on an independent card‑issuing infrastructure.

Additionally, the script developer integrated Cardyfie into their scripts (such as virtual card and payment solutions) either intentionally or without clearly verifying and disclosing the full dependency chain to buyers.

As a result:

Buyers believe they are purchasing an independent or complete solution

In reality, the service depends on Cardyfie → which itself depends on finup.io and other upstream providers

When downtime, compliance actions, or service limitations occur at the upstream level, end users and resellers have no control, no direct communication, and no accountability path

I am not making allegations about intent.
However, this lack of transparency regarding API dependency and upstream reliance creates serious business and financial risk for buyers.

This structure caused me over $1500 in losses, operational disruption, and customer trust issues.
