# Determining the API Hostname

> Identify your Fynapse API hostname and understand how it maps to web, API, and auth endpoints.

## Overview

This article will guide you on how to determine the correct hostname for accessing the API endpoints.

## Finding your API Hostname

The hostname for your Fynapse instance is typically provided during your onboarding process. If you are unsure about your instance hostname, contact your professional services representative or refer to your service provisioning details.

Your instance will be accessible at the following base URL structure:

`https://HOSTNAME/`

## API Hostname Structure

Once you have identified your HOSTNAME, you can use the following structure:

| **Endpoint**    | **URL Format**                | **Purpose**                    |
| --------------- | ----------------------------- | ------------------------------ |
| Web Application | `https://HOSTNAME/web`        | Access the web-based interface |
| API Base        | `https://HOSTNAME/api`        | Interact with API endpoints    |
| Auth Token      | `https://HOSTNAME/auth/token` | Retrieve authentication tokens |
