# App Connections

Connect the services you use, select compatible accounts in workflow nodes, and discover the available action reference.

## Connect once, select where needed

Open **App Connections** in your organization. Choose the service you need and complete its protected sign-in or connection form. Then select that account in the workflow node’s inspector.

The connection picker is the authority for which account types an action supports. An account connected for one service or one processing path may not be usable in another.

## Connections are organization resources

Check the organization before creating or selecting an account. Importing a workflow does not transfer access to another team’s connection. When moving a workflow, select destination accounts and resources explicitly.

Enter access credentials only in the application’s protected setup. Do not put passwords or access keys in workflow Properties, customer messages, shared JSON, or support screenshots.

## Choose the action and permissions together

A signed-in account can still lack access to a particular file, calendar, channel, store, or database. Verify the exact resource the action will use. Start with a small read operation when possible.

Connected-service quotas and charges are separate from a promise that an action appears in the node picker. Check your provider account and current Chatigram plan.

## Events need their own setup

Some integrations offer automation-specific connections or event actions. A normal account connection does not automatically subscribe a workflow to every event. Check the event source, trigger, and any remaining setup shown in the application.

## Browse the integrations

This is the currently documented selection. Chatigram continues to add nodes, triggers, App Connections, and integrations. Use each page’s review date and the current application selectors to check what is available now; this catalog is not a fixed limit on future features.

The guides below group the actions currently described in the Chatigram catalog. Use the filter to find a service. For every individual action, the [node reference](/reference/nodes/) lists its fields, outputs, and declared branches.
