Release Notes for New Webhook Signature Version and Key

We are rolling out a new webhook signing public key and increasing the webhook public key version.

If you verify webhook signatures, you must update your implementation to select the public key based on the X-Webhook-Key-Version included in each webhook request. Webhooks signed with the new key will use the new key version and will fail verification if your integration continues to use the previous public key.

Please ensure your webhook verification logic supports the new key version before the rollout.

See the Webhook Signature Verification Guide for the public keys and verification details: Webhooks Overview
