Hi @SK3250,
Welcome to the DocuSign Community!
We are glad to have you here and can't wait to help share as much knowledge as possible.
I am sorry to hear that you haven’t been able to use your Workday integration due to this authentication error, but I will share more details on the topic.
From a DocuSign point of view, the error you reference will only appear if you have updated the credentials (password, email, access token) related to the user building the connection between DocuSign and Workday.
Taking this into consideration, you would need to ensure that your credentials have not changed, and, if they haven’t and you can use them in DocuSign eSignature, the problem must be related to Workday’s setup.
In this scenario, it will be in your best interest contact Workday directly, so they can investigate the issue in more detail.
Feel free to let us know if you need further assistance with this.
Thank you for using DocuSign, we hope you have a wonderful rest of your day!
Best regards,
Alejandro R. | DocuSign Community Moderator
