Facebook/Instagram keyword trigger is breaking Klaviyo authorization — has anyone seen this?

Question

I’m running into a weird issue with the Klaviyo Facebook/Instagram integration and wanted to see if anyone else has experienced this.

My Meta/Facebook integration was working before, but now Klaviyo loses Facebook authorization when a user sends the configured keyword in a Facebook/Instagram chat automation.

I already tried the basic reset steps:

Removed the Klaviyo/Facebook connection
Removed Klaviyo from Facebook Business Integrations
Re-accepted the Meta Custom Audience terms
Reconnected the Facebook/Meta integration from scratch
Confirmed the page is tied to my personal Facebook account through a Meta Business Portfolio

The strange part is that it seems to break specifically at the keyword step.

Current behavior:

Klaviyo/Facebook shows connected.
A user sends the configured keyword in chat.
Klaviyo/Facebook authorization breaks or becomes disconnected.
I reconnect the integration.
If that same user then sends their email address in the same chat thread, the email capture works and authorization does not break again.

So it does not seem like the email capture step is the issue. It seems like the keyword listener / keyword trigger itself is causing the authorization problem.

For additional context, we are a lawful firearms/FFL ecommerce business. I understand there may be additional rules around firearms content, especially SMS/MMS and Meta-related automations, but I’m trying to figure out whether this is:

a Meta permission issue,
a Klaviyo/Facebook integration bug,
a keyword-trigger/webhook issue,
a Business Portfolio/Page ownership issue,
or some kind of content/policy flag happening when the keyword is sent.

Has anyone seen a Facebook/Instagram keyword trigger break Meta authorization like this?

Also, if Klaviyo staff sees this, is there a way to confirm whether the authorization is being revoked by Meta, by Klaviyo, or by a specific permission failure tied to the keyword automation?

Hey ​@deerforddefenseI think Meta is revoking the OAuth token, not Klaviyo. When a keyword is sent and the automation fires, ,Klaviyo makes an API call back to Meta's Messenger platform to process that event. If Meta's automated content policy systems flag something about that interaction, they can revoke the connected app's access token mid-session.Klaviyo's integration then reads the revoked token as a disconnection and marks the integration as unauthorized.I would suggest what you try right now is to test with a completelyneutral keyword (something like "HELLO" or "INFO") that has zero association with firearms. If the integration holds after that keyword fires, you have confirmed that Meta is pattern-matching on the keyword content or business context. If it breaks with a neutral keyword too, the issue is more likely tied to your Page's business category or an app-level permission problem.I also think that,, if you are able to connect to klaviyo’s live chat support,Klaviyo's Support team might be able pull logs to tell you exactly whether Meta sent back a token_expired or permission_denied error code at the moment of disconnection.I hope this helps,CheersArpit
