In principle, anything delivered on the client side can be read.<\/p><p>Use a server-side secret manager or a secure environment configuration with restricted access.<\/p><h4><strong>Separate testing and production<\/strong><\/h4><p>A sandbox and a production environment must use different credentials and endpoints. Test data should not appear in production reports, and a test key must not be able to process actual refunds or payments.<\/p><p>Make the environment visually recognizable to minimize errors during development.<\/p><p>Are you unsure whether to choose a plugin or an API?

An application that reads payment statuses may not need to be allowed to process refunds or make account changes. Where possible, restrict the allowed IP addresses, domains, or merchants.<\/p><p>Use separate credentials for each application or vendor so that access can be revoked on a targeted basis.<\/p><p>When creating a link, it's important that you <a href=\"https:\/\/omespay.be\/en\/kassasystemen\/kassakoppeling-betaal-api\/\"><strong data-start=\"456\" data-end=\"508\">Securely connect your cash register to your payment terminal or payment API<\/strong> <\/a>is linked.<\/p><h4><strong>Rotate and brake in time<\/strong><\/h4><p>Update credentials in accordance with the provider\u2019s policy and immediately upon suspicion of a breach, a change in personnel, or the expiration of a supplier contract. Test rotation without extended downtime by temporarily overlapping old and new credentials in a controlled manner, if the provider supports this.<\/p><p>Record the owner, creation date, rights, and scheduled expiration date without entering the value itself in the registry.<\/p><h4><strong>Log in securely<\/strong><\/h4><p>Logs may contain references, timestamps, and error codes, but must not include PINs, full card details, or secrets.
