# Setting up an API account

Setting up an API account is as easy as inviting a colleague to collaborate with in TerraIndex.

Just make sure the "API account" checkbox is checked, and a representative username is chosen.

Information

After saving the new account, and opening the new account again, the "Pin code" field will be available for you to generate your own API key.

# Usefull code snippets

## C# .NET

## Zip Stream class

Information

This is a Zip Stream class you can use to extract a zipstream.
