Project Overview

This app facilitates seamless integration with UPS services, including shipping, tracking, and address validation, within ERPNext.

Key Components

1. UPS Client (ups_client.py):

   • Manages API requests to UPS.
   • Handles session management, token generation, and authorization.
   • Includes methods for session creation and closure, token fetching and setting, and making generic UPS API requests.

2. UPS Shipment Doctype (ups_shipment):

   • Defines the structure for shipment records.
   • Contains logic for preparing and sending shipment requests to UPS, and handling responses including tracking numbers and label generation.

3. UPS Settings Doctype (ups_settings):

   • Stores UPS account settings and credentials.
   • Provides functions for retrieving the API base URL, bearer token, client ID, and client secret.
   • Manages access token expiration and renewal.

4. Additional Doctypes:

   • UPS Shipment Package and UPS Shipment Charge for structuring packages and charges related to a shipment.

Installation

1. Clone the repository into your bench apps folder: bench get-app https://github.com/alyf-de/ups_integration.git.
2. Install the app: bench install-app ups_integration.
3. Configure the UPS Settings in ERPNext with the necessary credentials and preferences.

Usage

1. Set up UPS Settings with your UPS account details, including API credentials.
2. Create a UPS Shipment document in ERPNext, filling in details like shipper, recipient, and package information.

Development

Key areas for improvement include:

• Expanding the UPSClient class to cover more UPS API endpoints.
• Enhancing the UPS Shipment Doctype with features like real-time tracking updates.
• Customizing the user interface and workflow to better fit specific business processes.
