# Popular connectors

> Common business apps that Flow processes connect to, such as Salesforce, ServiceNow, Slack, and Microsoft Teams, with a link to each connector.

A connector lets a workflow work with another app, such as reading a Salesforce record, creating a ServiceNow ticket, or posting a Slack message, without writing the API call yourself. In the **Add node** panel, each connector is listed by app name in the **Connector** category, and opens the list of its actions.

These are some of the apps that workflows commonly connect to. Each link opens the page of the connector in the Integration Service guide, which lists its actions and events, and describes how to authenticate.

## More connectors

The connectors available to you depend on your organization. The **Connector** category of the **Add node** panel lists all of them. [Connectors](/integration-service/automation-cloud/latest/user-guide/connectors) in the Integration Service guide describes how connectors work, and its sidebar lists the page of every connector.

If an app has no connector, call its API with [HTTP Request](node-http-request.md).
