SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Frappe/ERPNext REST endpoints can misbehave when errors are not clearly defined or communicated, leading to silent failures and poor client handling.

Core Features & Use Cases

  • Provides a standardized mapping of common HTTP status codes to Frappe exceptions (400/417 for validation, 403 for permission, 404 for not found, 500+ for server errors).
  • Enforces explicit input validation, permission checks, consistent error responses, logging, and retry/backoff patterns for 5xx responses.
  • Useful for building robust API modules, webhooks, and external integrations with predictable error handling and audit trails.

Quick Start

Setup a whitelisted API endpoint to raise specific exceptions, log errors, and return structured error payloads to clients.

FAQPage Schema
How do I handle REST API errors in Frappe to prevent silent failures?

To handle REST API errors in Frappe and prevent silent failures, you can map HTTP status codes to specific Frappe exceptions. This enforces explicit input validation, permission checks, and consistent error responses for clients.

How do I return consistent error responses from ERPNext webhooks?

Consistent error responses from ERPNext webhooks are generated by raising specific exception types based on validation and permission checks. This standardizes HTTP status codes and ensures structured error payloads are returned to external integrations.

Does Frappe v14 support standardized API exception mapping?

Yes, Frappe v14 supports standardized API exception mapping. This approach applies across Frappe versions v14 through v16, covering input validation, permission checks, error classification, and consistent error responses for REST endpoints.

What is the best way to implement retry strategies for Frappe 5xx server errors?

The best way to implement retry strategies for Frappe 5xx server errors is by applying retry and backoff patterns. This ensures safe external API interactions and prevents overwhelming the server during temporary outages.

Why do my Frappe API endpoints return generic 500 errors instead of validation messages?

Frappe API endpoints return generic 500 errors instead of validation messages when explicit input validation is missing. Mapping 400 and 417 status codes to Frappe validation exceptions ensures clients receive accurate error classification.

Can I log API errors and create audit trails for external integrations in ERPNext?

Yes, you can log API errors and create audit trails for external integrations in ERPNext. By implementing error callbacks and logging alongside consistent error responses, you achieve predictable error handling and comprehensive audit trails.
