Hi Hailong,

Thank you for bringing this issue to our attention. In looking voer the docuemnts, I want to just make sure that you have done the following items. As it looks like there has been an erroro in setting up the account which is why you would get this.

• Have you checked to make sure that you have the correct account Id and secret Word, as shown here ..
• Have you setup the refresh tokens, as shown here , and all the ids at the top level of the files.
• You can also check out this previous thread that showed this same issue.

Hi,

I work with William and let me provide support to your concern.

To give more details about this error, this signifies that the access or refresh token being passed in your request is incorrect or invalid. Please note that the email address used to generate those credentials should have the appropriate access to the production account that you're trying to make an API request.

If you continue to encounter the said error while using email address that has the appropriate access to the production account, could you share with us the following details below via Reply privately to author option?

• Email address (used to generate those credentials)
• Customer ID (used for the API request)
• Complete API logs (request and response) generated when the error occurred
