Are the credentials the same for the Mailbox API and the Online Filing 2.0 API?

Yes. 

When you request API credentials the first time, we will create a B2B (business-to-business) account for your MyEPO Portfolio company and send your company administrator credentials consisting of an OAuth 2.0 client ID and client secret for this account. 

These credentials and the B2B account can be used for all MyEPO APIs, including the MyEPO Portfolio API and the Online Filing 2.0 API. 

Your company administrator will see the B2B account in list of company members in the administration area of MyEPO Portfolio and should assign Mailbox access rights. In addition, your company administrator should grant permissions for the B2B account to access portfolios of applications in the applications and patents area of MyEPO Portfolio. 

In Online Filing 2.0, your company administrator should first add the B2B user to your company and make sure that it has been assigned “draft rights” at minimum.  

For more information see the feature guide available on our webpage on exchanging data with us using an API which also provides links to the technical documentation in Swagger and step-by-step instructions.
