# Auth Access

To access all the functionality for your API Core Banking operations, you must generate an access token using the [Get Access Token](https://docs.udara360.io/udara360-docs-1/getting-started/authentication/accesstoken) API. This token is essential for successfully carrying out all your requests.

#### Authorisation Header <a href="#authorisation-header" id="authorisation-header"></a>

The access token will be used as a bearer token for all your API requests. The access token you generate from the /GetToken request functions as the bearer for your authentication. Place your JWT token, obtained after successful authentication, in the Authorization header of each request you send to the API.

```
curl  https://openapi.test.udara360.io/api/../v1

    -H  "Accept:  application/JSON"
    -H  "Authorization:  Bearer  {access_token}"
```
