Context
WhatsApp has tightened its security protocols, especially affecting new numbers and unofficial APIs. New numbers are considered suspicious and are easily blocked, making it essential to follow a "warming-up" process to simulate human behavior.
Additionally, we recommend having multiple lines connected to provide alternative communication channels with your donors.
Warming-Up Concept and Strategy
Warming up consists of gradually increasing the activity of a number before using it intensively.
Duration: 3 to 10 days
Key Activities:
✔ Send messages.
✔ Make calls.
✔ Update status.
✔ Participate in groups.
Recommended Steps:
🟢 Day 0:
Wait several hours before scanning the QR code.
Set up the profile and add contacts (20-50).
Send messages to 1-2 known contacts and receive responses.
🟢 Day 1-3:
Increase the number of conversations (gradually up to 10-15).
Send varied messages (text, images, links).
Participate in groups.
🟢 Day 4 and beyond:
Create or join more groups and participate actively.
Post status updates and send diversified messages.
Limit sending to 2 messages per minute and a maximum of 6 hours per day.
Tips to Avoid Getting Blocked
📌 Number Age:
New numbers are more vulnerable. Do not use a number immediately after registering it.
📌 Avoid Spam Complaints:
Have customers contact you first using links with pre-written greetings.
Personalize messages with the recipient's name.
Provide an option to stop messages (e.g., "STOP" command).
📌 Mass Messaging Activity:
Introduce activity gradually. Do not send bulk messages suddenly.
Maintain a balanced ratio of sent and received messages.
📌 Human Behavior Simulation:
Mimic real interactions: send random messages, respond promptly, and include natural pauses between messages.
Technical Recommendations
⚡ Randomize the intervals between messages and take breaks between batches.
⚡ Avoid sending unsolicited links, especially in the first message.
⚡ Use numbers with a good reputation, preferably non-virtual ones.
If a Number Gets Blocked
🚨 Change IP and device before registering a new number.
🚨 Perform a warming-up process with the new number.
Conclusion
Following these best practices minimizes the risk of getting blocked when using new numbers on WhatsApp's unofficial API. The key is to imitate human behavior, personalize interactions, and maintain a progressive and moderate level of activity.
