The two sections below cover each one - start with credentials, since your base URL is confirmed by the same delivery team.

​
Get your credentials

Credentials are provisioned by the Nitro delivery team. Depending on how your organization has configured the platform, you will receive either:
  • Basic Auth credentials - a username and password sent directly to you
  • OAuth2 credentials - a client_id and client_secret, available when your organization has an identity provider (IDP) configured
If you have not received credentials yet, contact your Nitro delivery team or project contact. See Authentication for a detailed explanation of the difference between these two methods.

​
Find your base URL

The API base path is always esig/webportalapi/v4. Your host is tenant-specific - each NSEV customer has a unique URL. It typically looks like:
The esig segment is required - the Web Application Firewall routes requests on it. Your delivery team will confirm the exact host for your environment.
Set your base URL as an environment variable from the start. All examples in this documentation use BASE_URL as the variable name.
