In the Adobe Commerce Admin panel, navigate to Stores -> Configuration -> Adobe Experience Manager. Configure the connection settings for Adobe Experience Manager, including the URL, authentication credentials, and other necessary information.

Step [4] – Set up data synchronization between Adobe Commerce and Adobe Experience Manager:

Define the data synchronization settings to determine which data (such as products, categories, pricing, etc.) should be synchronized between the two systems. Configure the frequency and scope of data synchronization, as well as any mapping or transformation rules if required.

Step [5] – Test and validate the integration: Perform tests to ensure that data is synchronized correctly between Adobe Commerce and Adobe Experience Manager. Verify that product information, pricing, categories, and other relevant data is accurately shared between the two systems.

Step [6] – Implement customizations (optional): If needed, develop customizations or enhancements to tailor the integration to your specific requirements. This may involve building custom components, templates, or workflows in Adobe Experience Manager or extending functionality in Adobe Commerce.

The Agile Manifesto is a set of document with key values and principles.

The four values of the Agile Manifesto are:

1. Individuals and interactions over processes and tools
2. Working software over comprehensive documentation
3. Customer collaboration over contract negotiation
4. Responding to change over following a plan

The 12 Agile Manifesto principles are:

1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2. Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout the project.
5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicity — the art of maximizing the amount of work not done — is essential.
11. The best architectures, requirements, and designs emerge from self-organizing teams.
12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

An e-commerce chatbot is a conversational AI tool designed to interact with users and provide assistance, information, and support within an e-commerce context.

The following below steps defines, how an e-commerce chatbot works:

Step-1 – User Interaction : The chatbot interacts with users through a chat interface, which can be embedded on an e-commerce website, mobile app, or messaging platforms like Facebook Messenger or WhatsApp. Users can ask questions or engage in conversation with the chatbot.

Step-2 – Natural Language Processing (NLP) : When a user sends a message or query to the chatbot, the chatbot’s underlying technology, such as natural language processing (NLP), analyzes and understands the user’s intent and the context of the conversation. NLP enables the chatbot to interpret user input and extract relevant information.

Step-3 -Knowledge Base and Backend Integration : The chatbot is typically connected to a knowledge base or a database that contains information about products, services, and other relevant data related to the e-commerce store. It may also be integrated with backend systems like inventory management, order processing, or customer relationship management (CRM) systems to access real-time data.

Step-4 – Responses and Recommendations : Based on the user’s input and the information available in the knowledge base, the chatbot formulates a response. It may provide answers to common questions, recommend products based on user preferences, provide order updates, or assist with other e-commerce-related tasks.

Step-5 – Personalization and Recommendations : E-commerce chatbots often leverage user data, such as browsing history, purchase history, and preferences, to personalize their responses and make relevant product recommendations. This helps enhance the user experience and increase the likelihood of conversions.

Step-6 – Transactional Capabilities : In some cases, e-commerce chatbots may have the ability to process transactions directly within the chat interface. Users can add items to their cart, initiate the checkout process, and even make payments, all without leaving the chatbot interface.

Step-7 – Continuous Learning : Chatbots can be designed to learn and improve over time. They can analyze user interactions, collect feedback, and adapt their responses based on user behavior and preferences. This iterative learning process helps the chatbot become more accurate, efficient, and personalized over time.

Magento 2.x / Adobe Commerce 2.x “Regenerate Url rewrites” extension add a CLI feature which allow to regenerate a Url rewrites of products/categories in all stores or specific store.

Need to use below magento2-regenerate_url_rewrites extension

https://github.com/olegkoval/magento2-regenerate_url_rewrites extension

Installation By Composer (“Regenerate Url rewrites” extension)

composer require olegkoval/magento2-regenerate-url-rewrites

How To Enable Extension

enable extension (use Magento 2 command line interface as below):

php bin/magento module:enable OlegKoval_RegenerateUrlRewrites

To make sure that the enabled module is properly registered, run ‘setup:upgrade’:

php bin/magento setup:upgrade

[if needed] re-compile code and re-deploy static view files:

php bin/magento setup:di:compile $> php bin/magento setup:static-content:deploy

HOW TO USE “Regenerate Url rewrites” extension:

Step[1] – To regenerate Url Rewrites of all products in all stores (only products) set entity type to “product”: >

php bin/magento ok:urlrewrites:regenerate --entity-type=product

because product entity type is default – you can skip it:

php bin/magento ok:urlrewrites:regenerate

Step[2] – To regenerate Url Rewrites in the specific store view (e.g.: store view id is “2”) use option –store-id:

php bin/magento ok:urlrewrites:regenerate --store-id=2

Step[3] – To regenerate Url Rewrites of some specific product then use option product-id (e.g.: product ID is “122”):

php bin/magento ok:urlrewrites:regenerate --entity-type=product --product-id=122

or

php bin/magento ok:urlrewrites:regenerate --product-id=122

Step[4] – To regenerate Url Rewrites of specific products range then use option products-range (Example regenerate for all products with ID between “101” and “152”):

php bin/magento ok:urlrewrites:regenerate --entity-type=product --products-range=101-152

• if in the range you have a gap of ID’s (in range 101-152 products with ID’s 110, 124, 150 not exists) – do not worry, script handle this.

or

php bin/magento ok:urlrewrites:regenerate –products-range=101-152

Step[5] – To save a current Url Rewrites (you want to get a new URL rewites and save current) use option –save-old-urls:

php bin/magento ok:urlrewrites:regenerate --save-old-urls

Step[6] – To prevent regeneration of “url_key” values (use current “url_key” values) use option –no-regen-url-key:

php bin/magento ok:urlrewrites:regenerate --no-regen-url-key

if you do not want to run a full reindex at the end of Url Rewrites generation then use option –no-reindex:

php bin/magento ok:urlrewrites:regenerate --no-reindex

if you do not want to run cache:clean at the end of Url Rewrites generation then use option –no-cache-clean:

php bin/magento ok:urlrewrites:regenerate --no-cache-clean

if you do not want to run cache:flush at the end of Url Rewrites generation then use option –no-cache-flush:

php bin/magento ok:urlrewrites:regenerate --no-cache-flush

if you do not want to display a progress progress bar in the console then use option –no-progress:

php bin/magento ok:urlrewrites:regenerate --no-progress

Regenerate url rewrites of category

Step [1] – To regenerate Url Rewrites of all categories in all stores set entity type to “category”:

php bin/magento ok:urlrewrites:regenerate –entity-type=category

Step [2] – To regenerate Url Rewrites of some specific category then use option category-id (e.g.: category ID is “15”):

php bin/magento ok:urlrewrites:regenerate –entity-type=category –category-id=15

Step [3] – To regenerate Url Rewrites of specific categories range then use option categories-range (e.g.: regenerate for all categories with ID between “4” and “12”):

php bin/magento ok:urlrewrites:regenerate --entity-type=category --categories-range=4-12

if in the range you have a gap of ID’s (in range 4-12 category with ID “6” not exists) – do not worry, script handle this.

If you use options –category-id or –categories-range then you can skip option –entity-type=category – extension will understand that you want to use a category entity.
