The statuses of a transaction are PENDING, RECEIVED and LOSS. The status of a transaction can only be determined and changed by us if you activate automatic reconciliation for your recipient account.
If automatic account reconciliation is not active, the transaction always remains in PENDING status. It is not possible to set the status manually using the API and/or UI. You can activate the automatic account reconciliation under https://manage.onlineueberweisen.com/merchant/bankaccount . Please note that you need the necessary rights for this setting.
