# I’ve updated my E-Waybill System account credentials in Zoho Books but I’m getting an error that my credentials are incorrect. What should I do?

In Zoho Books, you have to enter your GSP credentials to connect Zoho Books with the E-Waybill System website. The GSP credentials are different from your E-Waybill System website credentials.

Read our FAQ on [generating GSP credentials](/in/books/kb/e-way-bills/add-zoho-books-as-your-gsp.html) to learn more about generating GSP credentials.
