Development of a robust n8n workflow to secure access to the Echo AI application, managing user credits and preventing abuse through advanced controls.

Automation Workflow for Security and Access Management (Echo AI)

Project Context
This project is part of a complex backend architecture designed to power "Echo AI," an innovative application. Echo AI allows users to transform a simple product image and an inspiration image into a professional creative brief for advertising, merging styles and products to generate impactful visuals. My role was to create an essential pillar for the sustainability and integrity of this service.

Challenge and Objective
The main objective was to implement a sophisticated access control system to prevent abusive and unauthorized use of the Echo AI application, while efficiently managing the resources (credits) allocated to users. Without such a system, the infrastructure could be overwhelmed by malicious or excessive requests, leading to unforeseen costs and degradation of the legitimate user experience.

Implemented Solution
I designed and deployed a powerful automation workflow using n8n. This workflow acts as an intelligent guardian, integrating several security and management mechanisms:

Credit Management: Precise tracking of credit usage per user, ensuring that each interaction complies with defined quotas.
IP Address Verification: Implementation of IP-based controls to identify and block suspicious or excessive traffic sources.
JWT Authentication: Use of JSON Web Tokens (JWT) to secure access to functionalities, guaranteeing that only authenticated and authorized requests are processed.
Robust Data Storage: Integration with Google Sheets for dynamic and easily accessible management of user data and security configurations.
Webhooks and Integrations: Leveraging webhooks for fluid communication between different parts of the system, allowing real-time responsiveness to requests.

Impact and Results
This system effectively secured access to Echo AI, significantly reducing the risks of abuse and optimizing resource usage. It ensures a fair and reliable user experience while protecting the operational integrity of the application. The modularity of the n8n workflow also offers great flexibility for future evolutions and adjustments of access policies.

Creation of a sophisticated AI agent that automates and personalizes large-scale WhatsApp messaging, optimizing marketing campaigns and customer communication.

# AI Agent for Automated WhatsApp Campaigns

## Context
In the current digital communication landscape, reaching customers in a personalized way and at scale is a major challenge. Manual WhatsApp campaigns are not only time-consuming but also lack the necessary personalization to effectively engage the audience. This project aimed to overcome these limitations by designing an intelligent automation solution.

## Challenges
The main challenges included:
*   **Scalability:** Sending thousands of messages without manual effort.
*   **Personalization:** Generating unique and relevant messages for each contact, beyond simple templates.
*   **Reliability:** Ensuring proper message delivery and managing failures.

*   **Integration:** Linking various platforms (spreadsheets, messaging APIs, AI, notification systems).

## The Solution: An Intelligent Workflow
I developed a robust AI agent, orchestrated via a detailed workflow, to manage the entire lifecycle of WhatsApp campaigns. Here are the key steps:

1.  **Workflow Trigger:** The process starts on demand or at a scheduled time.
2.  **Data Acquisition:** A list of contacts is read and imported from a Google Sheet, serving as a dynamic database for the campaign.
3.  **Loop Processing:** For each contact, a series of actions is executed:
    *   **Cleaning and Formatting:** The phone number is standardized to ensure compatibility with the WhatsApp API.
    *   **Personalized Message Generation:** The Gemini API (Google's Artificial Intelligence) is used to create a unique and contextually relevant message for each recipient, thus increasing engagement.
    *   **Sending via API:** The generated message is sent to the contact via the Evolution API, a reliable solution for WhatsApp communications.
4.  **Result Management:**
    *   **Real-Time Update:** The sending status (success or failure) is immediately recorded in the Google Sheet.
    *   **Error Handling:** In case of failure, errors are captured and documented for later analysis, allowing for continuous optimization.
5.  **Final Report and Notifications:**
    *   **Result Compilation:** Once the campaign is finished, an aggregated report is compiled, summarizing the overall performance.
    *   **Automated Alerts:** This report is then automatically sent via Telegram and email to stakeholders, ensuring maximum transparency and responsiveness.

## Technologies Used
*   **Google Sheets:** Contact management and status tracking.
*   **Google Gemini API:** AI-powered personalized content generation.
*   **Evolution API:** WhatsApp message sending interface.
*   **Telegram API:** Campaign completion notifications.
*   **Email Sending Service:** Additional email notifications.
*   **Workflow Automation Tools:** Process orchestration and execution.
*   **Regex / String Processing Functions:** For number cleaning and formatting.

Intelligent AI Agent for Automated and Personalized WhatsApp Campaigns

Deployment of Régina, an AI assistant on WhatsApp, to manage the entire sales cycle and continuous customer support. The chatbot qualifies leads, books appointments, sends quotes, and answers FAQs 24/7, transforming the business into an automated, ultra-responsive system.

This project illustrates the power of an AI assistant working for you, even while you sleep. At 3 a.m., while the competition risks losing customers due to lack of responsiveness, our AI assistant on WhatsApp is capable of qualifying a lead, scheduling an appointment, and even sending them a personalized quote. This is the new standard: a chatbot that manages your business and your customers 24/7.

Following Régina's success on our website, we adapted this assistant for WhatsApp, a direct and instant communication platform. The result is an indefatigable AI agent that grows your business while you focus on the essentials.

**Key Features of the WhatsApp Assistant:**

✅ **Complete 24/7 Customer Relationship Management**:
- **Automatic Lead Qualification**: The AI asks the right questions to identify the most relevant potential clients.
- **Intelligent Appointment Booking**: Connected to calendars, it proposes slots in real-time.
- **Instant FAQ Answers**: It answers all frequent questions without ever losing patience.

✅ **Support for All Communication Formats**:
- Manages text messages, images, audio files, and documents.
- Maintains a complete history of discussions for personalized follow-up with each client.

**Project Impact:**
- **Continuous Conversion**: Prospects become clients, even outside business hours.
- **Increased Customer Satisfaction**: Clients receive instant answers to their requests.
- **Business Automation**: The company runs on autopilot, freeing up time for strategic tasks.

The question is no longer whether a business needs an AI assistant, but rather why it doesn't have one yet. This project, achieved through a combination of **nocode** and **custom development**, demonstrates how we automate a business to multiply its results. It is a concrete example of our ability to transform business processes for maximum efficiency.

AI Assistant on WhatsApp for 24/7 Customer Relationship

Design and deployment of a custom chatbot for the BOVO Digital website. This virtual assistant automates appointment booking, manages team availability, answers FAQs, qualifies leads, and optimizes the sales process, allowing the team to focus on high-value tasks.

This project perfectly illustrates the value of automation and the importance of developing internal solutions, even for a specialized agency like BOVO Digital. For months, the creation of a chatbot for our own site had been postponed, due to lack of time, as client priorities always came first. Finally, in a dedicated morning, the project came to life and quickly demonstrated its strategic impact.

The developed chatbot was designed as a true virtual assistant, capable of handling several critical aspects of the prospect journey:

✅ **Automated Appointment Booking**: The robot is connected to the team's calendars to directly propose available slots to prospects. No more tedious back-and-forth by email.

✅ **Intelligent Availability Verification**: Thanks to conditional logic, it can cross-reference calendars and identify the best time slots in real-time, ensuring maximum fluidity.

✅ **Answers to Frequently Asked Questions**: A dynamic FAQ module has been integrated to immediately handle recurring requests (pricing, deadlines, services offered, collaboration process, etc.). This significantly reduces response time and improves the user experience.

✅ **Lead Qualification**: Before any team member intervenes, the chatbot asks strategic questions to evaluate the prospect's relevance and commercial potential. Unqualified prospects are thus automatically filtered out.

✅ **Commercial Pre-negotiation**: Although the negotiation function is still in the testing phase, the chatbot is capable of guiding prospects towards the right price ranges, preparing the ground for the sales team.

The implementation relies on a combination of **nocode** technologies and **custom development**. Nocode allowed for the rapid setup of the conversational interface and simple logic, while custom development provided the necessary flexibility to handle specific cases (team calendar integration, advanced qualification scripts, exception handling).

**Project Impact:**
- Drastic reduction in time spent on unqualified prospects.
- Increased company responsiveness to incoming requests.
- Improved user experience through 24/7 availability.
- Productivity gains for the team, now focused on strategic missions.

Beyond immediate benefits, this project highlights an essential lesson for any entrepreneur: it is crucial to take the time to develop your own internal tools. The leverage effect is considerable, as an optimized internal process multiplies the company's ability to deliver value to its clients.

This chatbot is not just a technological gadget; it is a true **growth lever**. It illustrates how intelligent automation, well thought out and well integrated, can transform the organization and results of a business. At BOVO Digital, this project has become a concrete showcase of our expertise in automation and AI applied to business processes.

In summary, this project combines **strategic vision**, **speed of execution**, and **technical expertise**. It shows that a well-designed internal tool can be a very high-return investment, while strengthening the company's credibility and efficiency with its clients.

Technologies and tools mobilized: integration of nocode solutions for the conversational base, custom development for complex cases, calendar management API, automated qualification scripts, and internal databases for response management.

This project now constitutes a flagship example of BOVO Digital's ability to design and deploy intelligent solutions that transform how businesses interact with their prospects and optimize their operational efficiency.

The prospect received the Calendly link... but STILL hasn't booked? No question of letting them go! My Make.com automation takes over for Ecom Soldiers! I implemented a Make.com scenario for "Active Reservation Tracking" which ensures that every hot prospect has every chance to take action.

Active Follow-up of Unclicked Calendly Links

Reminder system at 24h, 6h, and 15min before the appointment to limit no-shows.

Forgotten Appointment = Lost Sale! My Make.com Automation that GUARANTEES your Prospects Show Up! For Ecom Soldiers (and for any business that lives off its appointments!), a "no-show" is a net loss. So, I implemented an automated reminder system via SMS and WhatsApp (via Twilio), driven by Make.com and Google Sheets, to maximize the attendance rate.

Automated Appointment Reminders

Webhook triggered on every response, automatic routing to the correct AI scenario.

WhatsApp Response from a Prospect? 📲 My Make.com Automation Knows WHO It Is and WHAT To Do! In the super-qualification funnel I set up for Ecom Soldiers, every interaction counts.

So, I implemented a Make.com scenario dedicated just for this: the CAPTURE and intelligent SORTING of WhatsApp responses.

Intelligent WhatsApp Response Processing

Follow-ups at 6 am and 12 pm if the lead does not respond, with Telegram alert and tracking in Google Sheets.

Lead SILENT after the first qualification message? 🥶 Don't panic, my Make.com automation KEEPS WATCH (and intelligently follows up!) for Ecom Soldiers! In our super conversion funnel, we know that a prospect can be distracted, busy... or just need a little "nudge" to respond. Allowing silence to set in after the first WhatsApp/SMS contact risks losing a potentially golden lead! 📉 That's why I developed a specific Make.com scenario to manage these silences and attempt to re-engage the prospect (or alert the Sales team if necessary).

Automatic Follow-up for Silent Leads

Creation of an intelligent, multi-channel conversion funnel (WhatsApp, SMS, Email) connected to Calendly, Twilio, Google Sheets, Systeme.io, and Make.com.
