# Multi-Org Support

### Overview

Catalyst allows you to [create](https://docs.catalyst.zoho.com/en/getting-started/catalyst-organizations/) and [manage](https://docs.catalyst.zoho.com/en/getting-started/catalyst-organizations/#manage-organizations) multiple organizations within your Catalyst account. A unique Org ID will be generated for every organization you create. You can [create individual projects](https://docs.catalyst.zoho.com/en/getting-started/catalyst-projects/#creating-a-catalyst-project) in each organization and also assign [access permissions](https://docs.catalyst.zoho.com/en/getting-started/set-up-a-catalyst-project/profiles-and-permissions) to people contributing to the project. 

You can only have one organization in your account as the default one. The organization marked as default will be logged in automatically when you sign in to your Catalyst account every time. 

While you execute an API from Catalyst, it will be executed for the default organization automatically. For instance, when you pass the project ID in your API request, Catalyst will automatically look for a project with the same ID in your default organization. However, you can execute an API for other organizations that are not the default by exclusively passing the unique Org ID of those organizations in your requests.

### Usage

You can pass the Org ID as a header in an API request to access a project in that organization in this format:

**Sample API Header Format**

```bash
 -H CATALYST-ORG: 15090237

```

You can check a complete sample request from the [Request Format](https://docs.catalyst.zoho.com/en/api/introduction/request-format/#RequestFormat) section.
