# Platform Access

> What you need before making your first request: credentials and your tenant base URL.

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](/docs/nsev/authentication/credentials) 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:

```
https://your-tenant.sign.gonitro.com/esig/webportalapi/v4
```

The `esig` segment is required - the
[Web Application Firewall](/docs/nsev/build/guides/gotchas#the-web-application-firewall-is-strict)
routes requests on it. Your delivery team will confirm the exact host for your environment.

<Tip>
  Set your base URL as an environment variable from the start. All examples in this documentation
  use `BASE_URL` as the variable name.

  ```bash theme={null}
  export BASE_URL="https://your-tenant.sign.gonitro.com/esig/webportalapi/v4"
  ```
