You can terminate seller accounts through the Finix Dashboard or via our APIs.
There are several reasons to terminate a seller merchant account after approval, including suspected fraud, compliance violations, excessive chargebacks, or merchant churn. The seller's merchant account state will immediately update to Terminated.
Terminating a seller merchant account will:
Disable payment processing (
processing_enabled: false)Disable settlements (
settlement_enabled: false)Disable refunds (
refunds_disabled: true)
If a merchant is terminated by mistake, please contact the Finix Support Team.
On the Merchants > Merchant Accounts page, you can see all Merchants in your system. Click on the Merchant to navigate to their account page.

On the Merchant page, click the three-dot icon in the top-right corner, then select Terminate Merchant Account from the dropdown menu.

Choose a reason for terminating the merchant account from the dropdown menu. Then, enter a description explaining the reason (maximum 1,000 characters).

Terminating the merchant account will disable processing, settlements and refunds. The action cannot be reverted.
