WhatsApp sync
WhatsApp synchronization keeps a business WhatsApp account and your own systems describing the same reality: the same messages, the same attachments, the same order of events. WhatSyncs performs that synchronization continuously across every number you connect, and reconciles what it has already seen so nothing is recorded twice.
Scope
Being specific here matters more than sounding impressive. This is the full list of what WhatSyncs synchronizes from a connected session.
Every message your customers send to a connected number, as it arrives.
Replies sent from the phone, the desktop client or the WhatSyncs API — all three are synchronized.
Status transitions are delivered as their own events, keyed to the original message.
Voice notes, images, video, PDFs and documents, alongside the message they arrived on.
When the linked session exposes it, existing conversation history can be backfilled.
The chat a message belongs to, with the contact identity WhatsApp provides for it.
Media availability and history depth depend on what the linked WhatsApp session exposes. WhatSyncs synchronizes what is available rather than promising every message ever sent.
Real time
A batch import tells you what happened yesterday. Conversation data is only useful while the conversation is still going, so WhatSyncs is event driven end to end: a message is normalized and delivered to your endpoint within seconds of arriving.

Media
A synchronization that only carries text loses the part of the exchange that usually matters most: the brochure that was sent, the photo of the damage, the voice note explaining the exception. WhatSyncs treats media as first-class content.
WhatsApp conversation sync is the continuous process of copying messages, status changes and attachments from a WhatsApp account into another system so both hold the same record of the conversation.
The hard part is not the copying — it is doing it without gaps when a session reconnects, and without duplicates when the same message arrives through more than one path.
Every message carries a stable identifier. WhatSyncs matches realtime events, reconnect replays and history batches against that identifier before anything is delivered onward.
Deliveries also carry an idempotency key, so if your endpoint times out and a retry follows, your integration can recognise the repeat and update the existing record.
When the session reconnects, WhatSyncs catches up on what it missed and marks the connection as syncing until it is current.
Messages recovered during catch-up flow through the same reconciliation, so a customer who wrote during the outage appears once, in the right order.
Yes. Each connected number is synchronized independently, with its own session state, and every event names the connection it came from.
That is what makes it practical to route sales traffic and support traffic to different places in your systems from one integration.
FAQ
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.
Every message carries a stable identifier, and WhatSyncs reconciles messages seen through real-time events, reconnects and history synchronization against it. Webhook deliveries also carry an idempotency key so a retry does not create a second record in your CRM.
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.
Yes. Voice notes and other audio messages are treated as media: they are synchronized with the conversation and made available for download through the API.
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.
