Invalid checkout domain

[crimson inlet]

Hi team — I’m seeing an issue in production with subscriptions. Everything works in testing, but production fails with this error:

Invalid checkout domain: https://live.checkout.dodopayments.com/

on testing, i am using:- https://test.checkout.dodopayments.com

so it working fine on testing

This happens because live.checkout.dodopayments.com is not a valid checkout domain.

What to do:

• ✅ Test mode: https://test.checkout.dodopayments.com (correct)
• ✅ Live mode: use your own production domain (e.g. https://yourapp.com)
• ❌ Do not use live.checkout.dodopayments.com anywhere

Fix steps:

1. Update your production integration to open checkout from your site domain.
2. Ensure your checkout/session is created with live API keys.
3. If using Inline or Overlay checkout, initialize SDK with:

   mode: "live"
   

4. Retry the subscription flow.

If this still fails, your production domain may not be whitelisted—email support with your live domain.

The endpoint is incorrect; the correct one is:

Test - https://test.dodopayments.com/checkouts
Live - https://live.dodopayments.com/checkouts

i am trying
this
Test - https://test.dodopayments.com
const checkoutUrl = new URL(
/checkouts/buy/${process.env.DODO_API_SUBSCRIPTION_PRODUCT_ID},
process.env.DODO_CHECKOUT_LINK,
);

Test - https://test.dodopayments.com/checkouts
const checkoutUrl = new URL(
/buy/${process.env.DODO_API_SUBSCRIPTION_PRODUCT_ID},
process.env.DODO_CHECKOUT_LINK,
);

So I am getting this error in testing
This test.dodopayments.com page can’t be found

When I am using this
Test - https://test.checkout.dodopayments.com/
const checkoutUrl = new URL(
/buy/${process.env.DODO_API_SUBSCRIPTION_PRODUCT_ID},
process.env.DODO_CHECKOUT_LINK,
);
It's working fine

Yes

You can use a checkout session instead of a static link, as static links are quite difficult to manage as url becomes lengthy. Checkout sessions are easier to handle.

ok

do you have any doc link for that
