Testing split payouts involves testing multiple steps: * Seller Creation * Payment Session Creation * Payout and Settlement ## Seller Creation To create sellers in Sandbox, go to **Settings** → **Sellers**, select **Test** and click **Add Seller**. * In the **Organization number** field, put the organization number of the seller you want to test. * In the **Seller ID** field, put any value that would represent the seller in your system. It can be anything, but it needs to be unique. For automatic approval, check **Fast-track seller status** and select **Automatic approval** from the dropdown. After clicking continue, you will reach this screen: The seller will then be approved automatically within a few minutes. ### Testing with the API It's of course possible to test sellers with the API as well. Follow this [guide](./add-payout-destinations#onboarding-your-merchants-through-the-api), and make sure to use the account id with a T-prefix. Use a bank account from [Test bank accounts](/docs/checkout/testdata/approvals/bank-accounts). For testing purposes you can also auto-approve, decline, or leave a new seller awaiting signature by adding magic values to `payout_destination_description`. See [Auto-approve sellers](/docs/checkout/testdata/approvals/auto-approve). ## Payment Session Creation Sessions can be created with the T-prefixed account as shown in [Creating Split Sessions](./creating-split-session). You can put a `payout_destination_id` created above in the split items, but any other value is also valid here. ## Payout and Settlement These are not available in the sandbox environment, as it is a complicated process involving payment providers and banks. As long as the seller exists and the session is created correctly, payouts and settlements are tested to work.
