Why WhatSyncs
Most WhatsApp products ask you to move your team into a new inbox. WhatSyncs does the opposite: it makes the systems you already run aware of what is happening on WhatsApp.
WhatSyncs is a connectivity layer, not another system of record. Nothing migrates, nobody retrains, and your reporting keeps working the way it does today.
Sales, support, leasing, branches, regions. Each number is its own connection with its own event stream, managed from a single place.
Incoming and outgoing messages, status updates and connection events are delivered to your endpoint in real time, signed and retried.
Voice notes, images, videos, PDFs and documents are synchronized with the conversation, so attachments land on the record instead of a phone.
Every connection is monitored continuously. A number that stops syncing shows up as unhealthy before your team notices missing conversations.
Bearer-token authentication, predictable JSON, idempotency keys, retries and delivery logs. The boring parts, done properly.
How it works
No migration project, no new inbox for your team to learn. Link the numbers you already use, and let your existing systems consume the events.
Link your authorized business WhatsApp account with the standard linked-device flow — the same pairing you already use for WhatsApp on desktop. Repeat for every number you run.
Link a device
Scan once from WhatsApp on the business phone.
Conversations, messages and available media are synchronized into WhatSyncs in real time, normalized into a consistent shape and reconciled against what has already been seen.
Events are pushed to your CRM or application through signed webhooks, and the REST API lets you pull conversations or send messages from the same number your team uses.
The path of a message
The path of a message
Sales, support, leasing, a branch in another city. Each WhatsApp number links once and becomes its own monitored connection.
Messages, status updates and available media are synchronized in real time and normalized into one predictable shape.
Realtime events, reconnects and history synchronization are matched against stable message identifiers, so one message stays one record.
Signed webhooks push events to your CRM or application, and the REST API lets you pull conversations or send replies from the same number.
Every session reports its health. When a number drops, you see it — and so does your alerting, through connection events.
Keep the CRM and the systems you already have. WhatSyncs connects WhatsApp to them.
The whole product, in one sentence
01 Multi-number management
Companies do not run one WhatsApp number. They run one for sales, one for support, one per branch, one per region — and each of them is a separate session that can quietly stop working. WhatSyncs treats every number as its own monitored connection with its own event stream, managed from one place.

02 CRM synchronization
A deal review should not require someone to read a screenshot from an agent's phone. WhatSyncs delivers incoming and outgoing messages to your CRM as they happen, with the attachments intact, against the contact they belong to.

03 Real-time webhooks
Register an HTTPS endpoint and WhatSyncs posts events to it as they happen: messages in both directions, delivery and read status, media that finished syncing, and connection state changes. Payloads can be signed, failures are retried with backoff, and every attempt is logged.
Developer experience
Send messages, retrieve conversations, download media and manage connections through a clean REST API — with signed webhooks, retries and idempotency keys so events can be processed safely.
04 Media synchronization
WhatSyncs securely synchronizes available media alongside your conversation data — voice notes, images, videos, PDFs and documents — and makes it available to your CRM through authenticated endpoints when it needs it.
05 Connection monitoring
WhatSyncs continuously monitors every connected WhatsApp session so your team can identify disconnected or unhealthy connections before conversations are missed. A dropped session is a business problem, not a silent one.
Health score
3 of 4 connections are syncing normally. One session needs to be re-linked.

Incident
06 History & deduplication
When the connected WhatsApp session makes it available, WhatSyncs can synchronize existing conversation history so a newly connected number does not start with an empty timeline — while making sure the same message never lands twice.
How far back history reaches depends on what the linked WhatsApp session exposes, so it is not guaranteed to include every message ever sent.

Security
Customer conversations are sensitive, so the platform is specific about what it does rather than decorative about it. Everything listed here describes how WhatSyncs actually works today.
All API and webhook traffic runs over HTTPS. Endpoints you register must be HTTPS as well.
Webhook payloads can be signed so your systems can verify that an event genuinely originated from WhatSyncs before acting on it.
Every API call is authenticated with a bearer token. Keys are scoped to your workspace and can be rotated or revoked.
Workspaces are logically isolated. Conversations, media and connections belong to one workspace and are queried within that boundary.
Synced media is served through authenticated endpoints rather than public URLs, so a link alone is not enough to read a customer's file.
Delivery logs record what was sent to your endpoints and how it responded, which makes integration incidents diagnosable rather than mysterious.
WhatSyncs is designed around security best practices. We do not currently hold SOC 2, ISO 27001 or HIPAA certification, and we will not claim otherwise. Read the full security page .
Use cases
The same events power a sales timeline, a support desk and an internal application. What changes is what your system does with them.
Pricing
Start free with three connections. When you need more numbers, pay per connected WhatsApp number — not per seat, not per message.

FAQ
If something here is unclear, the contact form reaches a person who knows the answer.
WhatSyncs is a WhatsApp connectivity platform. It synchronizes business WhatsApp conversations, media and multiple numbers with CRMs and applications through a REST API and real-time webhooks, so companies can keep the systems they already run.
No. WhatSyncs is infrastructure that sits between WhatsApp and your systems. There is no CRM to migrate to, no new inbox your team has to adopt and no workflow rebuild — your CRM stays exactly where it is.
Yes. Each business number is a separate connection with its own session, health status and event stream, and all of them are managed from one place. Teams commonly run separate numbers for sales, support, leasing, branches or regions.
Yes. Incoming and outgoing messages, message status updates and connection events are delivered to your endpoint as they happen. Payloads can be signed so your systems can verify that an event originated from WhatSyncs, and failed deliveries are retried.
Yes. Available media — images, videos, documents and PDFs — is synchronized alongside the conversation data and can be retrieved through the API, so attachments end up on the customer record rather than on one person's phone.
The Free plan gives you up to 3 WhatsApp connections and 1,000 active chats per month, with API access, webhooks, media sync, history sync and connection monitoring included. No credit card is required to start.
An active chat is a conversation with a single contact that had at least one synchronized message during the billing month. Ten messages back and forth with the same customer in a month counts once, not ten times.
Where the connected WhatsApp session makes it available, WhatSyncs can synchronize existing conversation history so your systems start with context rather than an empty timeline. How far back history reaches depends on what the linked session exposes, so it is not guaranteed to cover every message ever sent.
Connect up to 3 WhatsApp accounts and synchronize up to 1,000 active chats per month for free. No credit card required.
