A defensible answer in disputes
The audit trail shows exactly how and when consent was captured and for which category, which is the difference between a documented answer and no defence at all in a dispute.

What it does
How Wavy handles this
Every contact record stores how and when consent was captured (website form, checkout checkbox, in-store QR scan) along with which message categories they agreed to receive. Any broadcast or automated sequence checks this consent record before sending and immediately honors opt-out requests, including WhatsApp's own STOP-style replies.
A wellness clinic's WhatsApp number gets suspended after a batch of promotional messages goes to a list somebody exported from an old walk-in register — patients who gave their number for appointment confirmations, not marketing, and several reported the messages as spam. Nobody had a record proving what those patients actually agreed to.
Opt-in and consent management is the record that would have stopped that. Every contact stores exactly how and when consent was captured — a website form, a checkout checkbox, an in-store QR scan — and which specific message categories they agreed to. Any broadcast or sequence checks this record before sending, and an opt-out, including WhatsApp's own STOP-style replies, is honoured immediately across every pending send.

How it works
Step by step
- 01
Consent captured at the source
A website form, checkout checkbox, or in-store QR scan records the moment a customer agrees to be messaged, along with exactly which categories — order updates, marketing, appointment reminders — they specifically consented to receiving.
- 02
Every send checks the record first
Before any broadcast or automated sequence fires, it checks that each recipient has an active, category-matched consent record already on file, excluding anyone who genuinely doesn't have one on record from that specific send entirely.
- 03
An opt-out propagates immediately
A customer's STOP-style reply or an explicit opt-out request is detected and applied instantly, removing them from every pending broadcast and sequence across the whole account at once, not just the one they replied to.
- 04
Audit log stands ready for disputes
The consent audit exporter can produce a full compliance record — source, timestamp, category — on demand, giving the business documented proof if a customer ever disputes agreeing to be messaged at all in the first place.
Why it matters
What you get out of it
One opt-out covers everything
A customer who says stop is removed from every pending broadcast and sequence across the whole account at once, rather than having to separately unsubscribe from each list a business happens to run.
Consent matched to category
Consent captured for order updates doesn't get treated as consent for promotional content, which is exactly the mismatch that got the wellness clinic's number suspended.
The detail
What to know before you rely on it
Since November 2024, WhatsApp's policy places the burden of proving opt-in on the business, not on Meta — if a customer disputes ever agreeing to receive a message, it's the business that has to produce evidence, and the audit trail this capability maintains is that evidence. A business with no consent record has no defence beyond its own word against the customer's, which is a losing position in any dispute Meta adjudicates. This is not a theoretical risk: it is the exact mechanism the wellness clinic's suspension worked through.
Consent is category-specific, and this distinction is where businesses most commonly get caught out. A patient who provided their number specifically for appointment confirmations has consented to utility-category messages about that appointment — nothing about that consent extends to marketing messages about a seasonal promotion. Reusing consent captured for one category to justify sending a different category is a policy violation even though a consent record technically exists, because the record doesn't cover what was actually sent.
Failing to honour an opt-out is treated as seriously as never having consent in the first place, and it can lead to WABA suspension — the entire WhatsApp Business Account, not just the offending contact's messages. This makes the opt-out propagation worker one of the highest-stakes pieces of this whole capability: it has to catch and apply every opt-out signal, including WhatsApp's own built-in STOP-style replies, immediately and across every pending send, because a delay of even a day can mean one more message going to someone who already asked to stop.

If a customer disputes ever agreeing to receive our messages, what do we actually have to show?
Since November 2024, the burden of proof sits squarely with the business, not Meta — you need to produce the specific consent record: the source (website form, checkout, QR scan), the timestamp, and the category they agreed to. This system's audit log exists specifically to be that evidence; without it, a dispute comes down to your word against the customer's word entirely.
Can we message a customer about a sale if they only consented to order-status updates?
No. Consent is category-specific — agreeing to order-status updates doesn't cover marketing messages at all, and sending promotional content on the strength of a different category's consent is a genuine policy violation even though a consent record technically exists already for that contact on file. A separate, category-matched opt-in is required before any marketing messages can go to that person.
How fast does an opt-out actually take effect across all our campaigns?
Immediately, and across every single pending broadcast and sequence at once, not just the one the customer originally replied to in order to stop everything. The opt-out propagation worker is built to catch this instantly, including WhatsApp's own STOP-style replies, because failing to honour an opt-out promptly is treated as a genuinely serious policy violation that risks account suspension entirely.
What happens if we can't produce a consent record for a contact Meta is investigating?
Without a documented consent record, the business has essentially no defence in that dispute at all to fall back on, and the outcome can include restrictions or suspension of the WhatsApp Business Account itself. This is precisely the scenario the audit trail exists to prevent — a contact with no verifiable, category-matched consent shouldn't be receiving marketing messages in the first place.
