Short answer
Yes, you can connect WhatsApp to your CRM, and you do not have to replace the CRM to do it. marv.Inbox sits between the two: your team answers customers in a shared WhatsApp inbox, and every contact, lead and follow-up flows into HubSpot, Salesforce, Zoho, Pipedrive or monday.com without anyone copying details by hand. The flow runs both ways, so records imported from your CRM come back into the inbox with their history attached.
What a WhatsApp CRM integration actually needs to do
Most teams do not want another CRM. They want the one they already run reporting and forecasting on to stop going stale the moment a customer moves to WhatsApp. That is the real problem: a rep answers on their phone, agrees a price, books a delivery, and none of it exists anywhere your pipeline can see. The deal moves forward in a chat thread and backwards in your records.
So the job is not to rebuild your CRM inside a messaging tool. It is to make the conversation feed the system you already trust. marv.Inbox connects your WhatsApp number to a shared team inbox, then pushes what happens in those conversations into your CRM as structured records, and pulls your CRM records back so the person answering can see who they are talking to.
How a shared WhatsApp inbox works
Which CRMs connect, and what each connection does
HubSpot, Salesforce and Zoho are the connectors we have run end to end against real provider accounts. Pipedrive and monday.com are supported on the same framework. Each one connects over OAuth, so you authorise it from your own CRM account and no credentials are typed into a form. Access tokens are stored encrypted per workspace and refresh automatically.
Lead capture writes into the object each CRM actually expects: Contacts in HubSpot, a Lead record in Salesforce, persons in Pipedrive, and a mapped board item in monday.com. For monday.com you choose the board and columns yourself, and the connection stays in a pending state until a real read round-trips successfully, so a broken mapping is never mistaken for a working one.
Salesforce goes furthest today. It imports Contacts and Leads back into marv.Inbox on a schedule, tracks its own position so nothing is imported twice, marks the matching contact as a lead, and raises the follow-up task. When your rep completes that task in marv.Inbox, a completed Activity is written back onto the Salesforce Lead. The record in Salesforce reflects work that happened in WhatsApp, without anyone logging it.

How the data connects, in both directions
Inbound, every message from WhatsApp, Messenger or your website chat resolves to one contact identity. The same customer writing from a second channel does not become a second record, which is what makes the CRM push meaningful rather than a source of duplicates.
Outbound to your CRM, a qualified conversation becomes a lead in the object your CRM expects, carrying the contact details captured in the chat. Contact groups in marv.Inbox stay in sync with CRM audiences in both directions, so a segment built on one side is usable on the other for campaigns and follow-up.
Back from your CRM, imported records arrive with their history attached, so the person answering a new WhatsApp message can see an existing customer rather than a stranger. Ownership, assignment and internal notes live on the messaging side, where the work actually happens, while the pipeline stages and forecasting stay in the CRM, where your company already runs them.
Putting a whole team on one WhatsApp number
Why a pipe beats a replacement
Replacing a CRM is a project. It touches reporting, permissions, integrations, deal history and the habits of everyone in sales. Almost no team wants to take that on because a messaging channel grew. Treating WhatsApp as another source that feeds the existing system removes the choice entirely: nobody migrates, nobody retrains on a new pipeline, and the reporting your management already reads keeps working.
It also changes what happens when someone leaves. On linked devices, a rep who walks out takes the thread, the context and the informal promises with them. When conversations are attached to a contact record that lives in your CRM, the handover is a reassignment rather than an archaeology project.
The WhatsApp Business messaging rules that apply
What connecting it involves
First, your WhatsApp number connects to marv.Inbox. With coexistence mode the number keeps working in the WhatsApp Business app on your phone while the shared inbox runs alongside it, so nothing goes dark during setup.
Second, you authorise the CRM connector from your own CRM account over OAuth, and choose what a captured lead should create. For monday.com you also map the board and columns, and we verify that mapping against a real read before the connection reports as working.
Third, we switch the connector on for your workspace during setup, and confirm the first record lands where you expect it. From that point conversations flow into your CRM without anyone maintaining the link.
