3. Create application connections

Once permissions are in place, proceed to establish secure connections with the applications you plan to integrate. Within MuleSoft Composer, open the Connections tab and select New Connection. Choose the desired application and follow the authentication process, which may involve OAuth login or API key authorization. After successful authentication, a green check mark will appear beside the connection name, indicating that it is active. Each connection must be authenticated separately for each user or environment to ensure data security and compliance.

4. Build a new flow

After establishing connections, you can begin building your first integration flow. Navigate to the Flows tab and click New Flow to create one. Define the trigger that will initiate the process—such as when a new record is created in Salesforce—and specify the corresponding actions that should occur as a result, such as sending a message in Slack or creating a ticket in Jira. During this stage, configure the required field mappings to ensure accurate data is transferred between systems. This structure allows business processes to operate seamlessly and automatically.

5. Test the flow

In the Composer interface, select Test to simulate the workflow using sample data. Observe how data moves between the connected systems and verify that each step functions as expected. If any errors occur, review your field mappings, connection settings, or authentication credentials. Repeat testing until the flow executes successfully without issues.

6. Activate the flow

Once testing confirms that your automation works properly, you can proceed to activate it. Click Activate Flow in the Composer interface to enable automatic execution based on the defined trigger conditions. Activated flows will run in real time whenever the specified event occurs, eliminating the need for manual intervention. You can confirm activation by checking the flow’s status indicator in the dashboard.

7. Monitor and maintain flows

After activation, ongoing monitoring and maintenance help ensure that integrations continue to perform efficiently. Access the Flow Runs tab to review execution logs and track each instance of the flow. Successful runs are marked with a checkmark, while any errors are displayed with warning icons for troubleshooting. Periodically review your flows to identify areas for optimization, deactivate outdated processes, or duplicate existing flows for similar use cases.
