How to determine what URI to use for Stage API requests

Hello,

I have created API Credentials in our Stage Environment, successfully generated a Bearer Token, but am unable to complete requests using the stage environment company name and stage bearer token.

It returns ErrorMessage "Request to the instance Stage ** ** cannot be processed by this URI"
ErrorCode: "DATABASE_VERSION_MISMATCH"

What is the sandbox/stage uri I should be using? currently using "https://am-ce98c.corrigo.com/api/v1/query/"
