# Create API credentials

> This guide helps you to create an API user for consuming E-Invoice APIs.

To access e-Invoicing through APIs, you need to create API credentials on the E-Invoice portal. These credentials are used in the [E-Invoice Authentication API](https://developer.sandbox.co.in/api-reference/gst/compliance/endpoints/e-invoice/authenticate.md) to generate a 6-hour access token.

> [!WARNING]
>
> **Prerequisites:** You must have an active GST account and access to the [E-Invoice portal](https://einvoice1.gst.gov.in/).

## 1. Log in to the E-Invoice Portal

Log in to your account on the [E-Invoice portal](https://einvoice1.gst.gov.in/) using your GST credentials.
