ISV Partner program

Allowing Independent Software Vendors and their merchants to easily and efficiently integrate with Viva's platform.


Integrate new features, differentiate your business model and grow your business — all with the support of Viva.

Our Independent Software Vendor (ISV) Partner program enables you to offer your products to any merchant inside the EEA without the need to expand your operations outside your country. Since Viva will be collecting the fee from your merchants, there is no need for you to establish a local presence in each country.


Our ISV program allows you to add payment options to your retail or business software, help your customers complete transactions faster and easier, and introduce new features without having to use a third-party payment terminal or software.

Some of the main benefits include:

Merchant onboarding

In order to onboard merchants, you can utilise our API-based onboarding process. These APIs streamline the onboarding process, reducing manual intervention and saving time for ISV Partners and merchants. Real-time notifications for onboarding and account verification are also available, in the form of webhooks, simplifying integration and enhancing the user experience.

Connected account API calls

The merchant onboarding process can be initiated with the Create a connected account API call, and information can be retrieved with Retrieve information about a connected account.

Please see the steps below for details on how to onboard merchants:

In the Demo environment, the merchant will not be able to follow the Onboarding URL mentioned below, as the onboarding flow only applies to the Production environment

  1. You - as the ISV Partner - initiate the creation of a connected merchant account via our Create a connected account API call, receiving an Account ID (accountId) and Onboarding URL (redirectUrl) in the response

  2. This Onboarding URL is then shared with the merchant, who follows the URL to begin the onboarding process

  3. Throughout the onboarding process, Viva handles all due diligence and verification steps - also known as Know Your Customer (KYC) / Know Your Business (KYB) - with no further action or input required by the ISV Partner

  4. You can use our Retrieve information about a connected account API call to retrieve information on a merchant account, such as email address, verification status and invitation details. Importantly, this API call also returns the account’s Merchant ID, which is used when creating payments for the account - this is also returned in the Account Connected and Account Verification Status Changed webhooks, outlined below

Using our ISV Webhook APIs, you are able to set up webhook notifications on behalf of your merchants. These can relate to the onboarding process, as well as to day-to-day payments and transactions.

Please see the steps below for details on how to set up webhooks:

  1. Firstly, use our Retrieve webhook key API call to generate a webhook verification key to be used in the response of your webhook endpoints for verification purposes

  2. You can then use the Create webhook API to set up webhooks for your desired events. Specifically regarding the onboarding process, the following webhooks can be used:

In addition to the above, you can also use this process to set up webhook notifications for payment- and transaction-related events:

- Transaction Payment Created - triggered when a successful customer payment has been made to one of your wallets
- Transaction Reversal Created - triggered when a refund for a previous customer payment has been made successfully
- Transaction Failed - triggered when a failed customer payment has been attempted to one of your wallets
- Transaction Price Calculated - triggered when a Viva commission payment has been withdrawn from your account

Account upgrades

For merchants who opted for external payouts, they will be provided with a limited account. If desired, the merchant is able to upgrade to a full business account at any time via self-care. This will provide the benefits of Debit Card activation, the possibility to reduce commission fees to 0% & a local IBAN for the merchant.


In order to upgrade to a full business account, the merchant should:

  1. Log into their Viva account and navigate to Settings > Products:

  2. For the Payment account item, select Request now:

  3. A pop-up will be shown. The merchant should read the information, agree to the terms & conditions and once again click Request now:

  4. At this point, the system will check whether there is any additional data to be submitted by the merchant. If there are no extra requirements, the upgrade is completed.

    If further information is needed, the merchant will be redirected to the Customer data update process to provide one or more of the following pieces of information, and the upgrade process will move to a Pending state:

    • Proof of Residence
    • Proof of Business Establishment
    • Economic Profile
    • Video ID
    • Proof of TAX ID
    • Proof of Funds & Wealth
  5. Once all required information is successfully provided, the account will be upgraded to a full business account

The above information will be shown in Viva’s ISV Directory under your Partner profile.

Can I set up a different fee per merchant?

Yes, you can set up a different fee per merchant. You can even set up a different fee per transaction of the same merchant.

What if I have merchants using a currency other than mine?

If one of your merchants is in a country with a different currency from the one you have in your Viva account, we will perform the exchange conversion based on the ECB FX rate of the day that the amount will be credited and charge the money directly to your account.

What happens in case one of my merchant’s transactions is refunded?

If a merchant refunds a transaction to a customer, then the ISV fee that was withheld for this transaction will be reversed.

What will happen if my ISV fee is greater than the total amount of the transaction?

The payment will be declined. So we suggest you run a check to make sure your ISV fee will always be less than the total amount of an individual transaction.

When will I receive the funds from the ISV fees?

You should be expecting to receive your funds within the first 10 working days of the month following the month that the transactions were executed.
