Attio WhatsApp Integration: Sync Every Conversation to Your CRM

Attio is the CRM for teams that care about relationships — startups, VCs, sales teams, agencies. It captures email and enriches contacts automatically. But if your team communicates on WhatsApp, Attio is only seeing half the picture.

The Gap in Your CRM

Think about your last week of work. How many important conversations happened on WhatsApp? A founder you're evaluating. A client asking about deliverables. A partner sharing deal flow. A prospect following up after a meeting.

Now think about how many of those conversations made it into Attio.

For most teams, the answer is close to zero. Not because the conversations aren't important — but because manually logging WhatsApp messages is tedious and nobody does it consistently.

The result: your CRM shows email activity but misses the channel where real relationships are built.

How the Attio WhatsApp Integration Works

The integration connects your WhatsApp account to Attio using the linked devices protocol — the same technology behind WhatsApp Web. No WhatsApp Business API. No Meta approval process. Works with your regular WhatsApp number.

What happens after setup:

  • Every 1:1 WhatsApp message (sent and received) is captured in real time
  • Messages are automatically matched to Attio people records by phone number
  • Each message appears as a timestamped note on the person's record
  • Contacts not yet in Attio are created automatically
  • The integration runs server-side — no browser tab needed

Why Attio Teams Need This

Your relationship data is incomplete. Attio's strength is relationship intelligence — but it can only work with the data it has. If 50% of your communication happens on WhatsApp, your interaction counts, last-contacted dates, and relationship health metrics are all wrong.

Context gets lost between team members. When a colleague asks "when did we last talk to this person?", the answer in Attio might show an email from 3 weeks ago — even though someone on the team had a WhatsApp conversation yesterday.

Founder and investor relationships live on WhatsApp. For VC and startup teams, WhatsApp is the default channel for warm introductions, quick check-ins, and deal updates. These are the most valuable touchpoints — and they should be in your CRM.

Client relationships need full visibility. For agencies and service teams, client WhatsApp threads contain requirements, feedback, and approvals that should be part of the client record.

Setting It Up

The entire setup takes about 5 minutes:

  1. Visit whatsync.appstronauts.shop
  2. Connect your Attio workspace with your API key
  3. Scan the WhatsApp QR code from your phone
  4. Run the initial contact sync

From that point, everything is automatic. Every WhatsApp conversation flows into Attio without any ongoing effort.

How It Compares to Alternatives

Manual logging: Doesn't scale. Teams start with good intentions and stop within a week.

Zapier/Make: WhatsApp doesn't have an official API for personal accounts. Most no-code integrations require WhatsApp Business API, which is a completely different product designed for outbound messaging.

WhatsApp Business API: Requires Meta approval, a business phone number, and ongoing API costs. Overkill for teams that just want their conversations logged.

This integration: Works with personal WhatsApp. No API approval. No second phone number. Set it up once, forget about it.

The Result

Your Attio workspace becomes the single source of truth for every relationship. Email, calendar, and now WhatsApp — all in one timeline. Your team sees the complete picture of every contact, and Attio's relationship intelligence finally has the full dataset to work with.
