Key Difference

Use Cases

1. Completing tasks in Appian workflow
2. Filling forms (SAIL)

4. Submitting approvals

Service Account

1. Calling REST/SOAP APIs between systems
2. Running scheduled processes (like nightly batch jobs)

Permissions & Security

1. Service accounts often get least privilege necessary to perform the automated task.
2. Example:
3. A service account for API integration may only need access to read/write specific CDT objects and start specific processes.
4. Normal users get role-based access according to business functions.
