Let\u2019s learn how to integrate Klarna with your Synder account, allowing you to sync Klarna order payment and general financial data with your accounting software seamlessly.<\/p>\n\n\n\n


Setting up the Klarna integration from scratch<\/p>\n\n\n\n

1. Create an account<\/strong><\/h3>\n\n\n\n

If you are getting started with Synder, you will need to create a free trial account<\/a> first.<\/p>\n\n\n\n

Note<\/em><\/strong>:<\/strong> If you want to integrate your payment platform with QuickBooks Online or Xero, check out this guide<\/a>. For connecting your QuickBooks Desktop company, refer to this article<\/a>.<\/p>\n\n\n\n

2. Provide your business details<\/strong><\/h3>\n\n\n\n

Then, fill out the information about your business and hit the \u201cNext step\u201d button.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

3. Select the platforms you would like to integrate<\/strong><\/h3>\n\n\n\n

Now you need to select the platforms you would like to connect to Synder. Click \u201cView all integrations\u201d to see the list of all available platforms and select Klarna. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


Note 1<\/em>:<\/strong> Select all the services you use to receive payments. You can integrate them now or skip this step and invite someone with admin access to set them up later.<\/p>\n\n\n\n

Note 2<\/em>:<\/strong> When you integrate your payment platforms, such as Karna to Synder, the system automatically creates a clearing account<\/a> for each integration. This clearing account functions as a holding account, representing your actual payment provider within your accounting system.

4. Connect your accounting platform
<\/strong>Select the accounting company you would like to connect to Synder and click on the \u201cNext step\u201d.<\/p>\n\n\n\n

Note:<\/strong> If you are connecting to QuickBooks Online or Xero, you will be prompted to select the sync mode. Proceed with the desired option.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


Click on the \u201cNext Step\u201d to link your accounting company.

5. Generate Klarna API Keys<\/strong>
<\/strong>In another browser tab, open your Klarna account and navigate to settings. By default, it will open the Klarna API Keys tab, where you will need to click on \u201cGenerate new Klarna API Key\u201d.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


You will be presented with a username and a password. Make sure to save the  API Username<\/strong> and API Password<\/strong> somewhere, as they are necessary for the next step.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


<\/strong>6. Connect your Klarna account<\/strong><\/p>\n\n\n\n

Almost there! To complete the setup, you need to connect your Klarna and other payment platforms to Synder.

Get back to your Synder website tab, where you will be asked to provide API Username and API key.<\/p>\n\n\n\n

Copy and paste your saved \u00a0API Username<\/strong> into the Provide your API Username<\/strong> field.
Then copy your saved API Password <\/strong>and paste it into the Provide your API Key<\/strong> field. Click \u201cConnect\u201d.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


Select your bank account and Timezone and click \u201cNext\u201d.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n



7. Check the result<\/strong><\/p>\n\n\n\n

Once you\u2019ve connected Klarna, Synder will import and sync the most recent orders with your accounting system.<\/p>\n\n\n\n

You can see the imported orders in the \u201cTransactions\u201d \u2192 \u201cPlatform transactions\u201d tab. To see more details, click on \u201cExplain\u201d under the synced order.<\/p>\n\n\n\n
