API

An API defines a structured way to exchange data or request an operation between systems. In a programme, it can link purchases, eligibility, points, or orders. The contract, authentication, errors, limits, and rework must be documented to make the integration usable.

A concrete example

An API can receive a validated order and return its processing ID. A unique ID prevents the same transaction from being credited twice.

A point to consider

Simply covering the nominal case is insufficient. Document authentication, duplicates, errors, retries, and frequency limits.

Prepare a contract that can be used by both teams

For each exchange, provide an accepted example, a rejected example, the required fields, and the resumption rules. Define a correlation identifier to trace a transaction between systems. Test an interruption after processing but before receiving the response: the resumption must retrieve the result without creating a second credit. Also, plan for tracking rejections and ensuring version compatibility.

Questions to ask your team

  • Can we determine if a transaction was processed after an outage?
  • Are temporary errors and invalid data handled differently?

CRM

CRM refers to the practices and tools that organize customer relationship management and tracking. It can centralize contacts, interactions, and opportunities. Its connection to customer loyalty depends on the necessary data and expected actions. Synchronization must have a designated person responsible and explicit controls.

Loyalty Points

Loyalty points are a unit of acquisition and use defined by the programme. Their value depends on the rules of allocation, conversion, consumption, and validity. A balance must clearly distinguish between available, pending, used, and expired points to avoid ambiguity.
