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.

🔧 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.

🔍 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.
