How to Integrate Bitrix24 CRM with WhatsApp Using BuzzTree

For sales teams, WhatsApp is where most conversations with clients actually happen. But if those conversations don’t make it into your CRM, you lose valuable context, follow-ups, and tracking. Many sales teams have a tough time manually copying every lead message, client query, and sales follow-up from their WhatsApp accounts to their CRM. The result? More manual work, missed follow-ups, errors in entry, no single view of the customer, slower decision-making, and potential loss of business. Also, managers have little to no visibility into their teams’ conversations with clients. If a sales rep quits the company mid-way through a deal, other members can have real difficulty in closing the deal due to lack of visibility.
If your sales team uses both WhatsApp and Bitrix24 CRM, we have good news for you! Integrating WhatsApp with Bitrix24 via BuzzTree can centralize all your conversations, making your CRM the single source of truth. BuzzTree bridges the gap between your CRM and WhatsApp—whether you’re using personal WhatsApp or Business version—so you can focus on closing deals, not copying messages. Setting up this integration is quite easy and involves a few simple steps.

Step-by-Step: Connecting WhatsApp with Bitrix24

Setting up the integration might sound technical, but it’s actually a breeze with BuzzTree’s guided setup. Here’s how it works:

  1. Head to the BuzzTree Dashboard

If you are the admin, start by logging in to your BuzzTree admin dashboard. Navigate to the Integrations tab on the left-hand menu. You’ll see two options: Bitrix24 and Salesforce. Click on the Bitrix24 button to get started. Screenshots and tooltips will walk you through each stage, but here’s a quick overview.

  1. Connect Your Bitrix24 Account

After clicking on the Bitrix24 integration, you’ll be prompted to log in or register on your Bitrix24 account (if not already signed in). Once inside Bitrix24:

  • Click on Applications in left side menu
  • Then go to Developer Resources
  • Choose the “Other” section
  • In the new pop-up window, select “Local Application”
  1. Create a Local App in Bitrix24

Now you’re setting up a connector between BuzzTree and Bitrix24. In the Local Applications page:

  • Paste the provided Handler Path and Initial Installation Path into their respective fields (these URLs will be shown on the BuzzTree interface).
  • Check the “Script only” box
  • Under Permissions, select:
    • ✅ CRM
    • ✅ User
  • Click Save.
  1. Copy Your App Credentials

Once you save the local app, Bitrix24 will generate two crucial pieces of information:

  • Application ID (Client ID)
  • Application Key (Client Secret)

You’ll also need your Bitrix24 domain URL.

These are the credentials BuzzTree will use to connect to your Bitrix24 system on your behalf.

  1. Finalize Integration in BuzzTree

Head back to your BuzzTree dashboard. Paste the following from Bitrix24:

  • The Application ID
  • The Application Key
  • Your Bitrix24 domain URL
  • Click Save.

Your Bitrix24 CRM is now officially connected to BuzzTree. BuzzTree will now be authorized to send and receive data from Bitrix24 on your behalf—meaning WhatsApp messages can now synced to your CRM in real-time.

What You Can Do After Integration

The integration isn’t just about connecting—it’s about supercharging your workflows. Once connected, you can:

  1. Sync Contacts

One of the biggest reasons to integrate WhatsApp with Bitrix24 CRM is to bring all customer communication into one centralized system. At the heart of this integration is the ability to sync your WhatsApp contacts—and their messages—directly into Bitrix24. After the integration is complete and connection is established, the contact card on WhatsApp Web indicates whether that contact is connected to the CRM. Users can either link an existing contact if it’s already in the CRM or create a new one directly from WhatsApp. Creating a new contact from WhatsApp automatically links it. Upon linking a WhatsApp contact to a CRM contact, a new tab, “contact info,” appears in WhatsApp, populated with details from Bitrix24 such as name, email, company, title, industry, and responsible person. This allows sales managers to view CRM details directly within WhatsApp, eliminating the need to switch to the CRM. When it comes to syncing messages, BuzzTree gives you the flexibility to do this in both automated and manual ways, depending on how your sales team prefers to work.

Auto-Sync: Set It and Forget It

There are two ways to enable automatic syncing of WhatsApp messages:

  • Admin-Level Auto-Sync:
    Your admin can activate auto-sync for specific users from the Team Management tab inside BuzzTree. When this setting is enabled, all the linked contacts in the WhatsApp web of that sales rep will have their WhatsApp messages automatically logged into Bitrix24—no manual action is required.
  • Rep-Level Auto-Sync:
    If the admin hasn’t enforced this by default, individual reps can enable auto-sync for specific contacts directly from the WhatsApp interface. Once activated, future messages (not past ones) from that contact will automatically appear in the CRM.

This is ideal for reps who want to maintain control over what gets logged but still benefit from automation for high-value leads.

Manual Sync: Precision Control

For more nuanced syncing, manual sync should be your go-to tool. It allows sales managers to selectively sync important messages with Bitrix24. When manual sync is activated, checkboxes appear next to messages, enabling users to choose individual messages or select a range of messages, similar to Gmail’s shift-select feature, to be synced to the CRM. This is incredibly useful when the rep wants to de-clutter the CRM and store only relevant conversations.

  1. Create Activities From WhatsApp and View Linked Deals Inside WhatsApp

What if you could log activities, schedule reminders, or track deal progress—without ever leaving WhatsApp? Well, that’s exactly what the BuzzTree’s WhatsApp-Bitrix24 integration allows you to do. One of its standout features is the ability to create and manage Bitrix24 activities directly from your WhatsApp chat window. While chatting with a lead on WhatsApp, you can simply click on a contact card and create a new Bitrix24 activity—like a task, call, meeting, or even a deal update—with just a couple of clicks. No switching tabs, no copy-pasting. You can stay right where the conversation is happening and still log everything in Bitrix24 in real time. Once created, the activity gets instantly recorded in the Bitrix24 CRM timeline. It is linked to the correct contact or company. This helps reps to stay focused in the moment without having to remember to update the CRM later (and risk forgetting important details).

BuzzTree also shows any existing Bitrix24 deals for that contact right inside WhatsApp. As soon as a WhatsApp contact is linked to Bitrix24 contact, reps can see last open deal of that contact. They can view the stage, value, and status of each deal. This helps them decide whether to create a new activity, update an existing deal, or trigger the next step. This kind of two-way visibility ensures your CRM isn’t just a static record-keeping tool—it becomes an active extension of your daily workflow, right inside WhatsApp.

Why This Matters

  • Saves Time: No need to log in to Bitrix24 separately to create tasks or record updates.
  • Reduces Errors: Because everything is linked instantly and automatically, there’s no risk of forgetting to create a lead or tagging the wrong deal.
  • Keeps Everyone in the Loop: Since chat messages and activities appear in the Bitrix24 contact timeline, managers and teammates can stay updated without having to ping you for info.
  • Boosts Productivity: Salespeople spend more time on high-value conversations and less on mundane operational tasks.

It’s like having a mini Bitrix24 dashboard living inside your WhatsApp—giving you full control and visibility, without breaking your flow.

Final Thoughts

If your sales team spends hours chatting with leads on WhatsApp, but none of those conversations make it to your CRM, you’re missing a goldmine of insights. The WhatsApp-Bitrix24 integration is a match made for modern sales teams. You get the flexibility and speed of WhatsApp with the structure and visibility of a CRM—tied together in one seamless flow. So why not make WhatsApp your most powerful sales channel and your most organized one?
