What is Bank Integrations?
Bank integrations mean that, with your consent, banks can share data about your accounts and transactions with other approved services, or let them initiate payments on your behalf. This happens through secure, standardised connections (APIs), which, when powered by Open Banking, are regulated by the EU's PSD2 directive.
Think of it as a door you hold the key to. No one can walk through it without your permission, but once you've unlocked it, your accounting software, for example, can go in and retrieve exactly the information it needs and nothing more.
In concrete terms:
You're in control. Your other bank never automatically shares your data. You have to actively approve the connection yourself, and you can revoke consent and remove the linked account at any time.
Only approved providers. Only companies authorised by a financial supervisory authority (in Denmark, the Danish FSA) are allowed to receive data via Open Banking.
Strong customer authentication. When you link an account, you have to confirm it with two-factor authentication at your other bank, just like when you log in there yourself.
Safe standard transfers directly to your Lunar account. You can make secure standard transfers from your linked bank to your Lunar account.
Is it safe?
Yes. Bank integrations aren't a grey area or a loophole, but a regulated part of how banks operate across the EU today.
Our partner behind Connect Bank
Lunar works with Aiia, one of the largest Open Banking platforms in the Nordics, to enable multi-banking. Aiia is authorised and regulated on par with the banks themselves, and they're the ones who technically handle the secure connection between Lunar and your other bank when you use Connect Bank.
Aiia covers a wide range of banks across Denmark, Sweden, and Norway, so in most cases, you'll be able to link the account you need.
Example: Connect Bank in the Lunar app
Do you have an account at another bank alongside your Lunar account?
With Connect Bank, you can link that account to the Lunar app so you can see the balance and transactions from both banks in one place, without having to log into two different apps to get the full picture of your finances.
This is exactly what Open Banking makes possible: with your permission, Lunar retrieves data from your other bank, so you get one unified view of your finances instead of piecing it together yourself.
How to get started:
Open the Lunar app and go to Discover
Find 'Linked bank account'
Tap '+ Add bank'
Find your other bank on the list
Follow the flow on your phone
Connecting other applications to Lunar
In some cases you want to connect to Lunar from other applications. For example you might want to show your Lunar accounts in another bank app. These connections also occur with Open Banking.
How do I connect?
You start a connection attempt from the other application. As you follow instructions (changes based on the application) you have to approve the connection in the Lunar app.
The connection will show up as a push notification if you have that enabled and as a message on the home screen with the text:
“Approve connection”
“X would like to connect to your Lunar accounts”
Before you approve the connection, the Lunar app will tell you what the application wants access to.
Accounts and transactions - The applications can fetch information on your accounts and the transactions in them
Payment initiation - The application can start payments from your Lunar accounts. These will still have to be approved by you.
All connections automatically expire after 6 months. After this you have to re-connect using the same approach as your first connection.

I don’t recognise the name of the connection
Many applications use special systems to connect with Open Banking. Therefore, the name of the connection might not coincide with the application.
If you’re in doubt about a connection, you should confirm with the other application about their connection partner. You can also always disconnect an unknown connection, as you can always reconnect again.
