We've expanded our webhook authentication capabilities to include comprehensive HTTP header support for Bulk Payments webhooks. This enhancement ensures that all webhook types now provide consistent authentication options, enabling more secure and reliable integrations with third-party services and internal systems.

Bulk Payments webhooks now support both Fixed Value headers and Hashed Value headers, matching the authentication capabilities available across our other webhook implementations.

The update will be applied to everyone on our SaaS platform on 20/01/2026
