How to configure client certificate for consuming REST API in OutSystems
Application Type
Reactive

Hi everyone, I’m currently integrating an external REST API in OutSystems and I’m facing an issue related to client certificate authentication (mTLS). My situation: The external API works correctly in Postman only when I configure: Client certificate Private key Without the certificate, the API call is rejected. This indicates the API requires client-side certificate authentication. 
What I want to achieve: I want to consume the same API from an OutSystems application, and I need to know how to configure OutSystems so that it sends the client certificate with the REST request (similar to Postman).
I am working with O11.

I did some research and found out that I need to create a ticket for the Support Team so they can help me set up certification? Is that correct? If so, where do I need to create the ticket?

@Le Quang Trieu : If your OutSystems installation is on On OutSystems Cloud, then you need to reach out to OutSystems Support for the installation of the certificate ( for your specific case)  and details are provided at https://success.outsystems.com/documentation/11/setup_outsystems_infrastructure_and_platform/setting_up_outsystems/requesting_to_install_client_side_certificates_on_outsystems_cloud/

Instruction on how to raise a ticket is available at https://success.outsystems.com/support/outsystems_community/opening_a_support_case_with_outsystems/
