Dynamics 365 Business Central: HttpClient and remote certificate validation future changes.

Dynamics 365 Business Central

The AL HttpClient data type in Dynamics 365 Business Central allows for sending HTTP requests and receiving responses from a URI.
A basic AL code example for sending a GET request and receiving a response using HttpClient is provided.
Dynamics 365 Business Central on-premise may encounter SSL connection errors when connecting to endpoints with expired or invalid certificates.
Dynamics 365 Business Central online does not currently perform certificate validation for remote endpoints when using HttpClient.
Microsoft is aware of the issue and a change in HttpClient behavior is expected in Business Central version 25.x.
Future updates may introduce full remote certificate validation checks, potentially causing delays in establishing connections with external endpoints.
The new behavior will prioritize security, but may impact existing connections without valid SSL certificates.
Performance considerations include potential delays in executing AL code while waiting for HttpClient calls to complete on the Business Central Server.
