Understanding Voucher API

This explanation helps you understand key concepts and principles behind Voucher API, how they relate to each other, and why they work the way they do.

What is a voucher?

A voucher in our system represents a discount or promotional offer that can be applied to customer orders. Think of it as a digital coupon that contains all rules and conditions for applying a discount.

Voucher anatomy

Every voucher consists of several key components that work together:

  1. Identity and Type
  2. Unique identifier (code or ID)
  3. Discount type (percentage, fixed amount, or shipping)

  4. These determine how the voucher is recognized and what kind of discount it provides

  5. Value and Limits

  6. Actual discount value (e.g., 10% or $20)
  7. Maximum discount amounts

  8. These define scope and impact of the discount

  9. Conditions and Rules

  10. When the voucher can be used
  11. What it can be used for
  12. Who can use it

  13. These ensure the voucher is used appropriately

  14. Validity Period

  15. Start and end dates
  16. Time restrictions
  17. These control when the voucher is active

How validation works

Validation is the process of checking whether a voucher can be used for a specific order. It's like a security guard that ensures all rules are followed before allowing a discount to be applied.

Validation process

    B -->|Pass| C{Condition Checks}
    C -->|Pass| D[Validation Success]
    B -->|Fail| E[Validation Failed]
    C -->|Fail| E
  1. Basic Checks
  2. Verifies the voucher exists and is active
  3. Ensures the voucher hasn't expired
  4. Confirms the voucher hasn't been used

  5. These are the fundamental requirements

  6. Condition Checks

  7. Validates order value requirements
  8. Checks item eligibility
  9. Verifies customer restrictions
  10. These ensure the voucher is used correctly

Redemption lifecycle

Redemption is the process of actually using a voucher. It's like a transaction that converts a voucher into an actual discount.

    B --> D[Webhook Notification]
    C --> E[Analytics Update]
  1. Pre-redemption Phase
  2. Final validation checks
  3. Discount calculation

  4. This ensures everything is ready for redemption

  5. Redemption Phase

  6. Marks the voucher as used
  7. Records the transaction

  8. This is the actual application of the discount

  9. Post-redemption Phase

  10. Updates analytics
  11. Triggers customer events
  12. This maintains the system's state

Customer management explained

Customer management is about understanding and controlling how customers interact with vouchers. It's like a set of rules that ensure fair and effective use of discounts.

Customer interaction model

    A[Customer] --> B{Eligibility Check}
    B -->|Eligible| C[Usage Limits]
    B -->|Not Eligible| D[Restricted]
    C --> E[Usage Tracking]
  1. Eligibility System
  2. Customer segmentation
  3. Usage history tracking
  4. Purchase history analysis

  5. This determines who can use vouchers

  6. Usage Control

  7. Per-customer limits
  8. Time-based restrictions
  9. Value-based controls
  10. This prevents abuse and ensures fair use

Analytics and insights

Analytics in Voucher API provides insights into how vouchers are being used and their impact on your business.
