Integrating WhatsApp with Salesforce,without losing attribution
Your leads already write to you on WhatsApp; the problem is that those conversations die on a phone. With a native integration, every chat starts out as a lead in Salesforce, with its source campaign and its full history.
How do I integrate WhatsApp with Salesforce?
To integrate WhatsApp with Salesforce you need the WhatsApp Business API as the official channel, a verified number and an integration that creates and updates leads, contacts and opportunities directly in your org. The key is that every conversation keeps its campaign source: a lead that came from a click-to-WhatsApp ad is recorded in the CRM with that attribution, not as a stray contact.
There are two paths: a middleware sync that copies conversations between two systems, or an agent that runs directly inside the org and writes to your objects while respecting profiles and permissions. Sellium takes the second path, built by a team that has been a Salesforce partner since 2009.
WhatsApp sells, but without the CRM it does not learn
In Latin America, B2B leads write on WhatsApp before they fill out any form: messages on the channel average an open rate close to 98%, versus roughly 20% for email, according to the WhatsApp Business blog and 2025-26 industry roundups. The problem is not demand: it is that those conversations tend to live on a sales rep's personal phone.
When WhatsApp stays outside Salesforce, three things happen: the lead does not exist in the CRM until someone enters it by hand, nobody knows which campaign brought it in, and follow-up depends on each rep's memory. The real pipeline and the pipeline management sees drift a little further apart every week.
Integrating WhatsApp with Salesforce closes that gap: every conversation comes in through the WhatsApp Business API, is recorded as a lead or contact in your org and keeps the campaign that started it. Attribution stops being a reconstruction and becomes a data point.
Lost attribution means a blind budget: if you cannot connect each WhatsApp lead to the ad or campaign that brought it in, you cannot know which spend to repeat either. A native integration keeps that thread end to end, from the click to the close.
Three ways to integrate WhatsApp with Salesforce
Not all integrations are equal. The difference lies in where the data lives and how much gets lost on the way from the chat to your org.
The table sums up the three approaches we see most often at companies in the region, from the most manual to the most integrated.
| Approach | How it works | What gets lost |
|---|---|---|
| Personal number + manual entry | Each sales rep handles chats from their own phone and enters the lead in the CRM when they can | Attribution, response times and history: it all depends on each person's discipline |
| Middleware sync | An external messaging platform stores the conversations and copies them to Salesforce via API | Data stuck halfway between two systems, fields that don't map and duplicate contacts |
| Native agent in the org | An AI agent like Sellium runs the official API and writes directly to your Salesforce objects | Nothing structural: the lead is born in the CRM with its source, its history and your permissions |
Illustrative summary: the details of each approach depend on the vendor, the Salesforce edition and your existing flows.
Leads that arrive with their source already set
The value of the integration is not just speed: it is that every conversation enters the CRM with its full sales context. A lead who tapped a click-to-WhatsApp ad is not worth the same as one who scanned a QR code at a trade show, and your reporting has to be able to tell them apart.
With a native integration, this is recorded in Salesforce without anyone entering anything:
- Campaign source: the ad, QR code or site button that started the conversation, mapped to your Salesforce campaigns.
- Qualification data: budget, authority, need and timeline gathered in the chat, as lead fields.
- Full history: the conversation summary is stored in the record's activity, visible to whoever takes the deal.
- Owner and next step: assignment based on your territory rules, with the task or the booked demo already created.
Built by a Salesforce partner, not against Salesforce
Vantegrate has been a Salesforce ISV and Consulting Partner since 2009: Sellium is not a generic bot with a connector, it is an agent designed to live inside the org, respect profiles and permissions, and coexist with what you already have running.
That includes Agentforce, Salesforce's native AI agent platform. Sellium does not compete with your investment in the platform: it extends it to WhatsApp, the channel where your leads already are, with the WhatsApp Business API put to work for sales.
How we work on the platform, our consulting projects and our certified team are covered on our Salesforce page.
From the ad to the Salesforce pipeline, hands-free
This is how a lead flows from the first message to your campaign report, with no manual entry along the way.
The lead taps your ad or QR code
They come in through a click-to-WhatsApp ad, a QR code or the button on your site. The first message already carries the campaign reference.
Sellium replies over the official API
First response in seconds, at any hour. The conversation runs on the WhatsApp Business API with your verified number.
It qualifies while it talks
The agent answers product and pricing questions while gathering budget, decision, need and timeline without interrogating.
It creates the lead in your org
A lead or contact created or updated in Salesforce with the source campaign, the qualification fields and the chat summary.
Your team follows the deal in the CRM
Assignment by your rules, a booked demo when it applies and return-by-campaign reporting, all inside Salesforce.
The channel and speed, in numbers

Caveats: the email comparison is directional, because benchmarks such as MailerLite's 43.46% open rate are inflated by Apple Mail Privacy Protection; the Lead Response Management Study by Oldroyd, MIT and InsideSales.com is from 2007 and remains the classic reference on the subject. Measure your attribution against your own agreed baseline.
Sellium: WhatsApp and Salesforce in the same agent
The integration is not a separate project wired up afterward: it is Sellium's architecture from day one, up and running in weeks.

Vantegrate and SalesforceFrequently asked questions about integrating WhatsApp with Salesforce
What RevOps and sales teams usually ask before connecting the channel.
How do I integrate WhatsApp with Salesforce?
How do I integrate WhatsApp with Salesforce?
You need three pieces: the WhatsApp Business API (the official channel for businesses, with a verified number), an agent or platform that runs the conversations, and the integration that writes to your org's objects. Sellium covers all three in a single implementation: it runs the API, talks with each lead and creates or updates records in Salesforce while respecting your profiles and permissions.
Can I integrate WhatsApp with Salesforce using the free app?
Can I integrate WhatsApp with Salesforce using the free app?
Not directly: the WhatsApp Business app is designed for manual service from a phone and does not offer a CRM integration. To connect with Salesforce you use the WhatsApp Business API, which you sign up for through an official provider (BSP) and which lets you automate, integrate and serve customers with several users on the same number.
What happens to attribution from click-to-WhatsApp ads?
What happens to attribution from click-to-WhatsApp ads?
That is exactly what a native integration preserves: a lead that comes from an ad arrives with its campaign reference, and Sellium records it on the lead in Salesforce. That way you can measure how many conversations, qualified leads and opportunities each campaign generated, in the same reports you already use.
Does Sellium compete with Agentforce?
Does Sellium compete with Agentforce?
No: they work side by side. Agentforce is the platform's native agent, and Sellium complements it by specializing in the WhatsApp channel for sales, with qualification, quoting and logging in your objects. We have been a Salesforce partner since 2009; how we approach the platform is on our Salesforce page.
Which Salesforce objects does the integration touch?
Which Salesforce objects does the integration touch?
The ones you define: typically leads, contacts, opportunities and activities, plus the qualification fields your team uses. Sellium runs with an integration user that has the permissions you configure: it touches nothing beyond what is enabled, and every change is audited in Salesforce's standard history.
