**Requirements:** Admin role; the API key from section 3. 1. In **Integrations**, find the **MONEI** card (in "Available" status) and click **Connect**. 2. The "Connect MONEI" modal repeats section 3's help, so you have it at hand without going back to MONEI. 3. Paste the **MONEI API key** into the field. 4. Click **Connect**. **Result:** the Platform **verifies the key against MONEI for real** before saving anything. If verification fails, you're told the specific error (section 8) and no credential is saved. If it succeeds, the card switches to **Connected** and the **Bizum** method is activated by default (section 5) — the other methods MONEI supports (Card, Apple Pay, Google Pay) remain available but not activated, so as not to promise more than what you asked for.
