What is Server Script?
Server Scripts in ERPNext are Python snippets that run on the server for document events, API calls, or scheduled jobs — enabling custom business logic without a full custom app.
Types of Server Scripts
Go to Settings → Server Script → New. Choose Script Type: DocType Event (runs before/after save, submit, cancel, delete), API (creates a new REST endpoint callable via URL), or Scheduler Event (runs on a cron schedule). Write Python using the frappe API.
Server Script vs Custom App
Server Scripts are ideal for quick customisations — no deployment needed. For complex integrations, database-heavy logic, or version-controlled customisations, a Custom Frappe App is more appropriate. Server Scripts cannot access the file system or run system commands.
