Did you know there are legal requirements for using WhatsApp and Chatbots on your website?
I ask you this because very few websites integrate these tools correctly and legally.
If you already know Joinchat, you know that tools like WhatsApp and Chatbots are essential to optimize customer service on your website, so I’m not telling you anything new. These solutions not only streamline communication but also improve the user experience.
Now here’s the part you might not know: along with their benefits, there is a crucial aspect that is often overlooked in integration—legal compliance.
Integrating these tools without complying with regulations can expose you to penalties that may hurt your wallet and irreparably damage your business’s reputation. But if you do it correctly, you can also strengthen your users’ trust and improve their perception of your brand.
Can I use a WhatsApp icon on my website?
It’s a great idea, but only if you do it right. Including a WhatsApp icon on your website is a very common and effective practice to quickly connect with your customers. By clicking, the user can start a direct conversation with you from their device, which greatly simplifies and speeds up communication.
That’s why it’s important to learn how to integrate WhatsApp and Chatbots into your website 100% legally, complying with the GDPR (General Data Protection Regulation) and the LSSI (Law on Information Society Services).
But beware—WhatsApp is just like any data collection system. Managing data through WhatsApp means handling personal information (such as phone numbers, names, or messages).
That’s precisely why you must take into account data protection and e-commerce regulations, especially GDPR and LSSI, to avoid legal problems when using these tools professionally.
What does the GDPR and the AEPD require when using WhatsApp?
Every time a user contacts you through WhatsApp from your website, they are providing personal data. According to GDPR and the AEPD, any processing of personal data must have the explicit consent of the individuals concerned or be backed by a clear legal basis (such as contract execution or consent)
On the other hand, the LSSI regulates commercial communications and prohibits any commercial communication that has not been specifically requested or authorized by the recipient. In addition, companies are required to implement technical and organizational measures to prevent misuse of data.
Key points to comply with these regulations
Clearly and visibly inform:
Place a clear notice next to the WhatsApp icon or in your privacy policy, stating that user data (such as their phone number or messages) will be processed in accordance with GDPR. For example:
“By contacting us via WhatsApp, your data will be used only to respond to your inquiry, according to our privacy policy.”
Obtain explicit consent:
The user must give their free, informed, and specific consent before you use their data for any purpose, such as sending them a catalog, a business proposal, or future promotions. You can include a checkbox or a clear message before they start the conversation.
Avoid sensitive data. WhatsApp is not the safest channel for sharing confidential information such as health, financial, or sensitive personal data. If your business handles this type of information, choose more secure channels, such as encrypted email or specialized platforms..
Security measures. The AEPD insists that companies must adopt technical and organizational measures to protect data, such as encryption, internal privacy policies, and periodic audits to ensure compliance.
WhatsApp Business and Automated Messages
If you use WhatsApp Business, you can take advantage of features such as welcome messages or automated replies to improve the user experience. However, you must also follow certain rules:
- Informative welcome message: Set up an automatic message that explains how you will handle user data. For example:
“Hello! Thanks for contacting us. We’ll use your data only to respond to your inquiry, according to our privacy policy [link].”
- Spam prohibited: As mentioned, under Article 21 of the LSSI, it is forbidden to send commercial messages (such as offers or promotions) without the user’s express consent. If you want to use WhatsApp for marketing, request additional and specific permission for this purpose.
Can I use WhatsApp for marketing?
You can, but only if you follow these recommendations. Sending promotions, discounts, or campaigns through WhatsApp is a powerful strategy, but you can only do it if the user has given prior, clear, and specific consent.
For example, you cannot add phone numbers to a broadcast list and send advertising without permission. This could result in serious penalties for violating the LSSI or GDPR. Here’s an example of a sanction for this practice. A good practice is to include a checkbox in your contact form or next to the WhatsApp icon:
“I agree to receive offers and promotions via WhatsApp.”
Chatbots and Legal Compliance
Chatbots, whether basic or AI-powered, are fantastic tools to automate responses and collect information. However, they also handle personal data (names, emails, preferences, etc.), so they must comply with GDPR.
Apart from GDPR, the new AI Regulation has just been published, which includes a mandatory EU form (effective from August 2, 2025). This form requires AI model providers, including open-source ones, to publicly detail the data used to train their systems, such as datasets or scraped web domains.
Practical Recommendations to Do It Without Risks:
Notify users that the Chatbot collects personal data. You can include an initial message or a link to your privacy policy in the chat window.
- Visible privacy clause:
Ensure that the Chatbot displays a message or link explaining how the data will be processed. For example
“This chatbot collects data to improve your experience. See our privacy policy [link].”
- Automated decisions:
If your Chatbot makes automated decisions (such as customizing prices or denying services), you must inform the user and guarantee their right to human intervention, according to Article 22 of the GDPR.
Practical Recommendations for 100% Legal Integration
Let’s recap. To integrate WhatsApp and Chatbots safely and legally, follow these recommendations:
WhatsApp icon. Include it with a short legal notice or a link to your privacy policy.
Privacy policy. Detail how you will process the data collected through WhatsApp and Chatbots. If you need full and updated legal texts, including informative clauses for WhatsApp and Chatbot use, you can check my GDPR legal text template KITS.
Transparent Chatbots: Inform if the Chatbot collects data or makes automated decisions.
Manage cookies properly. When you integrate WhatsApp or Chatbots into your website, they may use cookies or similar technologies (like tracking pixels) to collect data on user behavior, personalize responses, or analyze interactions. According to the AEPD, cookies that are not strictly necessary (such as analytics or marketing ones) require prior user consent. Ensure that the banner allows users to accept or reject these cookies granularly. Tools like Usercentrics Cookiebot can help you manage them.
Automated replies. Set up informative messages in WhatsApp Business that explain data usage. Never send commercial messages without express consent.
Avoid sensitive data. Do not use WhatsApp to share confidential information.r información confidencial.
