Advance on centlec

To make sure we point you in the right direction, could you tell us a bit more about what you mean by "advance on Centlec"? Specifically, are you using a third-party app, custom integration, or API connection alongside QuickBooks Online? This information will help us understand where the error is coming from.

While we look into this further, let's perform a few troubleshooting steps to rule out any browser-related interference. Start by opening QuickBooks in a private or incognito window, or switch to a different browser.

If this is related to a third-party app integration, the error is most likely coming from that app’s API connection rather than from QuickBooks. In that case, we recommend reaching out directly to the app developer’s support team through the QuickBooks App Store. The app developer is responsible for maintaining their API sync and resolving token-related issues on their end.

Let us know what you find. We're happy to keep helping from here.
