Connecting a Viva softPOS to Wrapp takes two parts: first you locate your Merchant ID and Terminal ID in your Viva account, then you register them in Wrapp's Integrations. Once linked, every charge on the POS starts from the invoice, as required by the POS interconnection rules of AADE, the Greek tax authority.

### Part 1: Find your details in your Viva account

First, sign in to your [Viva account](https://www.vivapayments.com/).

**1.** From the main screen, go to `Settings → API Access`.

## Frequently asked questions

### Where do I find my Merchant ID in my Viva account?

Sign in to your Viva account and, from the main screen, go to Settings, API Access. Your Merchant ID is displayed there.

### Where do I find the Terminal ID (TID) of my Viva POS?

From the main Viva menu, go to Sales, Physical Payments, Terminals. The Terminal ID (TID) column lists the number of each of your terminals.

### Why do I need to connect my POS to my invoicing software?

POS interconnection is mandatory in Greece: AADE, the Greek tax authority, requires the amount charged on the terminal to come from an issued document. Wrapp, as an AADE-certified e-invoicing provider (YPAHES), covers this requirement automatically.

### Can I connect more than one Viva POS to Wrapp?

Yes. On the Settings, Integrations, POS page, click the "+" button and add each terminal with its own Terminal ID under the same Merchant ID.
