ClientId idk-node-1.0.10 is invalid

[pmggary]

It appears that as of today 2026-05-29 that the Sandbox has decided that using the clientId of 'sdk-node-1.0.10' is invalid.  This is the clientId that is hardcoded into the last release of https://github.com/AuthorizeNet/sdk-node

Using the exteranlConfig param on the constructor with a custom clientId makes this error message go away.

Hopefully this doesn't impact Authorize.net production before our next release,  if this was communicated in advance somewhere that I've missed I would love to know.

This appears to be a recent change on Authorize. Net’s side where the hardcoded SDK client ID  used by the Node.js SDK is now being rejected as invalid. As a workaround, specifying a custom  through the  parameter resolves the issue. If this behavior is intentional, it would be helpful for Authorize.Net to clarify whether it affects production environments and whether any advance notice or documentation was provided. Until an updated SDK release is available, overriding the client ID seems to be the recommended temporary fix.

Hello everyone! I was reading a tech blog about how to bypass regional restrictions using APK files instead of the Play Store. The blog recommended this program. What interested me was the claim that the mobile version is optimized for older Android devices. My phone has limited RAM and usually crashes on heavy sites here in Bangladesh. I installed the  and the difference was night and day. The interface loads instantly, and the odds update without lag. I am genuinely satisfied with the smooth performance!

Thanks for the heads-up. It looks like the Sandbox is now rejecting the default sdk-node-1.0.10 clientId. Using a custom clientId via externalConfig appears to be a working workaround until there's official clarification or an SDK update.
