SEB credentials

↑ Back to top

Once you have signed a contract with SEB, you need to generate and exchange certificates with them. If you have already done this, skip to the next section. If not, here’s how you do it: First, you need to generate a private key, which is used to sign all requests to the bank. Then, you need to generate a certificate signing request (CSR) from your private key – this is sent to the bank. If you are using Windows, ensure that you have OpenSSL installed. On Linux/Mac, OpenSSL should already be present. Open Terminal/Shell/Command Line and run the following commands:

openssl genrsa -out private_key.pem 2048
openssl req -sha1 -new -key private_key.pem -out csr.pem

You are asked for a series of data for the certificate:

• Country [AU]: 2-letter country code. One of EE, LV, LT. Example: EE
• State or Province Name (full name) [Some-State]: your company state/province. Example: Harju maakond
• Locality Name (eg, city) []: your company city/town/village. Example: Tallinn
• Organization Name (eg, company) [Internet Widgits Pty Ltd]: Example: Nööbid & Kindad AS
• Organizational Unit Name (eg, section) []: Can be left empty, but you can also enter “banklink” (without the quotes)
• Common Name (e.g. server FQDN or YOUR name) []: the domain name of your store. Example: www.mysuperawesomestore.com
• Email Address []: merchant’s (your) email address. Example: johndoe@example.com
• A challenge password []: leave blank (press Enter)
• An optional company name []: leave blank (press Enter)

As a result, you have 2 files in the directory you ran the commands from: private_key.pem, which contains your private key and csr.pem, which contains the certificate signing request (public key). You need to send the csr.pem file to SEB now and wait for their response. SEB will send you their public key and your Merchant ID – but it could take some time.

Test Mode

You can test the SEB gateway using the third-party Banklinks (for SEB Estonia) or Test Pay (for SEB Lithuania) services. These services allow you to create mock/test payments without having a contract with the bank. To set up testing for SEB Estonia, you need test credentials for your bank and the appropriate country from the Banklinks page.

1. Click SEB Estonia Test
2. Click Certificates
3. Copy the following to the gateway settings and save:
   • Copy Merchant ID to Test Merchant ID field.
   • Copy Merchant’s private key to Test Private Key field.
   • Copy Bank’s certificate to Test Public Key field.

To set up testing for SEB Lithuania, you need to create an account with Test Pay. Once logged in, generate certificates, create a “test shop” and get credentials.

1. Generate a test certificate using the Test Pay Certificate Generation tool. Save the private key and certificate body in your somewhere in your computer.
2. Download the SEB bank certificate from the list of certificates. This saves a file called seb.crt on your computer.
3. Select My Shops in User Menu
4. Select Add new store
5. Enter something meaningful as the Store name, for example: SEB Lithuania Test
6. Copy & paste the Store certificate that you generated in step 1 to the appropriate field.
7. Copy & paste the Store private key (without password) that you generated in step 1 to the appropriate field.
8. Copy & paste the Bank certificate that you downloaded in step 2. You can open the seb.crt file with a text editor, such as Notepad (Windows) or TextEdit (Mac OS) and simply copy it’s contents to the appropriate field.
9. Select “SEB” bankas as the payment gateway
10. Save – you should now be presented with Shop testing data
11. Copy the following to WooCommerce SEB Gateway settings and save:
    • Copy VK_SND_ID to Test Merchant ID field.
    • Enter any name to the Test Recipient Name
    • Enter any IBAN account number to Test Recipient Account
    • Copy Private Key (without password), that you generated in step 1 to Test Private Key field.
