ToolJet can connect to Zendesk APIs to read and write data using OAuth 2.0, which helps us to limit an application's access to a user's account.
## Connection
To establish a connection with the Zendesk data source, you can either click on the **+ Add new Data source** button located on the query panel or navigate to the **[Data Sources](/docs/data-sources/overview)** page from the ToolJet dashboard and choose Zendesk as the data source.
ToolJet connects to your Zendesk app using :
- **Zendesk Sub-domain**
- **Client ID**
- **Client Secret**
### Authorization Scopes
You can create a Zendesk data source with one of either of the two permission scopes :
You must first be a verified user to make Zendesk API requests. This is configured in the Admin Center interface in **Apps and integrations > APIs > Zendesk APIs.** For more information, see Security and Authentication in the [Zendesk Support API reference](https://developer.zendesk.com/api-reference/ticketing/introduction/#security-and-authentication) or [check out Zendesk's docs](https://support.zendesk.com/hc/en-us/articles/4408845965210).
