3rd Party: Brevo Connections Experiencing Sync Failures

Incident Report for Fivetran

Resolved

Description:
We identified an issue with the Brevo connector, which resulted in syncs failing with error: "Invalid date-time filter".

Timeline:
This issue began on 2026-05-08 16:30:00 UTC and was resolved on 2026-05-12 07:00:00 UTC.

Cause:
A recent update from Brevo resulted in the date format that the connector used being incompatible with the source API requirements.

Resolution:
The datetime formatter has been updated to ensure timestamps are always sent in explicit UTC format (Z) as expected by the source API. This resolved the connector failures and also handles any potential format variation going forward.
