Changes comparison

In order to avoid updating the entire Deante product database, we recommend introducing product version comparison into the integration system. For each product sent in the API, you can easily calculate the checksum (we recommend md5). If the checksum of the incoming product in the API differs from the one stored in the database, we update the product information.

Implementations

JavaScript

import md5 from 'md5'
// Downloaded product from customer database
const databaseProduct = {
    // Product information + additional md5 field
    versionHash: "78e731027d8fd50ed642340b7c9a63b3"
}

// Product downloaded from Deante API
const apiProduct = {
    // Product information from API Deante
}

const apiHash = md5(JSON.stringify(apiProduct));
const hasChanged = databaseProduct.versionHash !== apiHash
// If a change occurs hasChanged will be set to true
// This means that this product should be updated

PHP

// Downloaded product from customer database
$databaseProduct = array(
    // Product information + additional md5 field
    versionHash => "78e731027d8fd50ed642340b7c9a63b3"
);

// Product downloaded from Deante API
$apiProduct = array(
    // Product information from API Deante
);

$apiHash = md5(json_encode(apiProduct));
$hasChanged = $databaseProduct['versionHash'] !== $apiHash
// If a change occurs hasChanged will be set to true
// This means that this product should be updated
