How frequently can I safely cache the baseUrl?

Question

Before each request to the DocuSign REST API, I make a call to https://demo.docusign.net/restapi/v2/login_information. But the only information I need from that

Answer 1

Since it is a third-party API outside your control, I would recommend that you follow the requirements of the documentation, and make the call each time. There's no telling when they might change the internals of the API.
