Connecting WhatsApp by phone number

Instruction for connecting WhatsApp by phone number to NovaTalks

I. Connecting WhatsApp by phone number 📲

To connect WhatsApp, you only need to provide the phone number already registered in WhatsApp to the support group.

🔄 The connection process takes some time.

Once everything is ready, you will receive a QR code to scan.

What you need to do next:

• Open the link from the support group in your browser.

• Refresh the page (press F5 or the refresh button).

• Open the WhatsApp app on your phone.

• Go to the "Devices" (or "Linked Devices") menu.

• Select "Scan QR code" and scan the code from the computer screen.

• After this, WhatsApp will be successfully connected, and a new session will appear in the devices list.

⚠️ Important: preparing a new WhatsApp number before connecting

If the phone number has just been registered in WhatsApp, it is recommended to "warm up" the number before connecting to reduce the risk of blocking by WhatsApp.

🔧 What "warming up the number" means:

For a few hours, you need to have real conversations with 2–4 contacts. These should be simple, natural dialogues, for example:

• Hi, how are you?

• I’m fine, and you?

• I’m good too, thanks!

• What’s new?

Connecting WhatsApp by phone number is possible without warming up, but this increases the risk of blocking if the number is new.

⚠️ Warnings when connecting WhatsApp by phone number

Connecting WhatsApp by number is not official, and the algorithm of WhatsApp’s operation is closed — Meta does not publish the exact reasons for blocking.

🔍 From our experience:

Sometimes connection interruptions or account blocks may occur.

The main reasons for blocking are:

• repetitive messages

• frequent initiation of conversations with new contacts (for example, more than 30 outgoing messages per day is already a risk, especially for new accounts). This number is approximate and may vary depending on the history of the number.

🔁 In case of blocking, WhatsApp gives:

• 2 attempts to submit an unblock request

• After the third block, the number is permanently blocked without the possibility of recovery

📌 Recommendations:

• Do not start too many new conversations per day

• Vary the text of your messages

• Warm up new numbers before connecting

II. Differences between WhatsApp by number and WhatsApp Business API 🤖

✅ WhatsApp by number (unofficial connection)

• This is a regular WhatsApp connection by phone number.

• It does not work through the official API, so the stability is lower compared to WhatsApp Business API.

• Simple and quick connection

• You can message first immediately (without HSM templates)

• Group chats are supported

• Buttons are not supported

• Risks:

  • number blocking

  • disconnection of the active session

🏢 WhatsApp Business API (official connection from Meta)

• This type of connection is stable and officially supported by Meta

• A business page in Meta and its approval are required, which takes some time

• Requirements:

  • Create a business app in Meta

  • Link it to the page

  • Complete business and number validation

• Timeframes:

  • Business page registration — up to 1 hour

  • Company approval — from 1 to 6 months

  • App and number validation — up to 3 months

• To send the first message, HSM templates must be used, which must be pre-approved by Meta. An additional fee is also charged for each new initiated conversation (see Pricing Updates - WhatsApp Business Platform - Documentation - Meta for Developers).

• Buttons and interactive elements in messages are supported.
