We would like to inform that the outage has now been addressed for the most part, and the API numbers have resumed functioning.
We also want to provide you with a clear understanding of what happened and how 360Dialog is handling the situation.
What Happened:
Around 12:00 AM GMT, Meta switched from per-number webhooks to per-WABA webhooks without prior notice.
360Dialog identified the issue, alerted Meta, and began working to minimize the impact.
Meta is still finalizing a permanent fix.
