# Webhook Key Header Missing

Fixed an issue where webhook callbacks sometimes failed to fire or reach their destination, by reworking the webhook delivery pipeline and adding a new webhook key header for callback requests.

**This includes:**

* Reworked the webhook delivery pipeline
* Added a new webhook key header for callback requests

**How it benefits the Merchant**

This improves the reliability of webhook callbacks, reducing missed or failed integrations that merchants depend on for syncing orders, inventory, or other data with external systems.

**Potential FAQs**

Q: Do I need to update my webhook endpoint configuration?

A: Check with your account manager to confirm whether your integration needs to accommodate the new webhook key header.

Q: Will previously failed webhook calls be retried automatically?

A: The description doesn't mention retroactive retries — check with your account manager about any missed callbacks during the affected period.
