Hi,
Can you specify more clearly coz it's not clear what you are using the request & what you got.
You can share the screenshot or can message me the request, hope I can help you to consume the same.
If it is a kind of API which serves the request using the same HTTP Request object in terms of authorization then simple Outsystems REST API is not going to help you, rather you have to create a custom integration. I have faced this type of issue in past & resolved the same by creating Integration.
