Frequently Asked Questions

updateAppSettingsPage.faq.items.0.question
updateAppSettingsPage.faq.items.0.answer
Will updating the keys disrupt my shop?
If you save correct credentials, the transition should be immediate. If the new credentials are incorrect, checkout may fail temporarily—which is why we recommend testing the connection right away.
Can I switch from one processor to another?
No. A CartDNA app cannot switch from one processor to another processor. Each processor has different APIs and connection architecture. A new app and a new agreement are required.
Can I switch from test keys to live keys?
Yes. This is a normal update. Review your settings carefully, then test the connection and checkout flow before relying on live payments.
What should I do if the new keys do not work?
Check whether the keys are complete, correct, and tied to the right account. Review related configuration values. If the issue continues, contact CartDNA support and use the troubleshooting resources.

Need Help Updating Your CartDNA Connection?

If you need to edit keys, fix configuration errors, or connect a different account within the same processor, CartDNA support can help you do it safely. Take action before a setup issue affects checkout performance or customer trust.
