April 2025 Critical Patch 1

Developer Connect Webhook Critical Patch to Remove "Transfer-Encoding" Header

As part of the recent Encompass Webhook release, ICE Mortgage Technology has identified an issue related to Developer Connect webhook notifications.

Due to the upgrade of a development library, the "Transfer-Encoding" header with a value of "chunked" is now being added to Developer Connect webhook notifications. This header was not included in webhook notifications prior to this release.

The inclusion of the "Transfer-Encoding":"chunked" header has been observed to cause issues for clients' webhook endpoints that are not expecting this header. Specifically, these endpoints may not be able to process the notifications correctly, leading to a potential disruption.

Additionally, client webhook endpoints hosted in Azure have been found to not return the notification request bodies when the "Transfer-Encoding":"chunked" header is included. This can result in incomplete or failed webhook notifications.

To address these issues, a Critical Patch will be applied during our maintenance window on April 22, 2025. This patch will explicitly pass the "Content-Length" header and remove the "Transfer-Encoding" header from our webhook notifications. By doing so, we aim to ensure compatibility with all clients' endpoints and restore the expected behavior of our webhook notifications.

For any additional questions, please reach out to ICE Mortgage Technology Client Support.
