Connections
To connect to a system, whether it's a data source or a data target, create a connection with that system's standard connection or with an existing external named credential. You can connect to multiple systems within a flow and reuse each connection. You can create connections in the Integrations tab or in Flow Builder.
Standard Connection
This system uses OAuth2ClientCredentials authentication.
OAuth2ClientCredentials authentication obtains an access token from a user-defined path.
This system requires this credential information for its connections.
| FIELD | DESCRIPTION |
|---|---|
| Connection Name | Enter a unique connection name that helps you remember the details of this connection. Salesforce hides the credentials after you create the connection. Reuse connections as needed. Anyone with the Manage Integration Connections permission can see and use all connections in the org. |
| ClientId | Enter the OAuth client ID to use to authenticate the requests. |
| ClientSecret | Enter the OAuth client secret to use to authenticate the requests. |
| URL | Enter the URL to use to authenticate the requests. |
| Scope | Enter the scopes that the client can access. |
| Token URL | Enter the URL to use to get an access token. |
Named Credential Connection
Select a pre-existing named credential from Setup to use for your external system connections.
Before connecting to your external system with a named credential, first create or use an existing authenticated named credential and external credential that is enabled for your users.
To ensure a successful connection for use in a flow, use only one principal for each named credential.
- Use the same name for the named credential and its related objects, such as the external credential and external authentication identity providers. Labels for these objects can differ.
- Assign the user creating the connection the required user permission for the principal. Without this permission, the connection test fails and the connection remains inactive.
When you create a connection with an existing named credential, note these behaviors:
- Manage the named credential’s read-only details in Setup, not the Integrations tab. On the Integrations tab, you can only edit the connection's Connection Name and Description.
- Perform reconnections for the named credential in Setup. The Reconnect button isn’t visible on the Details page.
- Delete associated named credentials in Setup. Deleting a connection doesn't remove the credential.
Triggers
A trigger initiates the flow when a specified event occurs. Triggers are important for automating business processes because they react to real-time data changes in various systems. For more information about triggers, refer to Create a Flow with a Connector as a Trigger.
These Microsoft Excel triggers are available in Flow Builder.
- On New Spreadsheet
Actions
An action performs a specific task or operation within a target system. Use actions to automate tasks across different systems without manual intervention, based on conditions set in the flow. For more information about actions, refer to Create a Flow with a Connector as an Action.
These Microsoft Excel actions are available in Flow Builder.
