# Registration

You need to first register your client with sgID before any integration steps can begin. 

## Required information

sgID requires the following information from you to register your client:

<table><thead><tr><th width="184.40112994350278">Item</th><th>Description</th></tr></thead><tbody><tr><td>Display name</td><td>Maximum 25 character string representing your client to display to the end user</td></tr><tr><td>Allowed scopes</td><td>The set of scopes that your app is requesting authorization for to access. Refer to the <a href="/pages/mpSapcahgEAGnY3jZQUo">Data Catalog</a> for a full list of available scopes.</td></tr><tr><td>Callback URL</td><td>The URL that sgID will redirect after the end user authenticates with Singpass. We assume that you have access to the underlying codebase and service for this URL.</td></tr></tbody></table>
