How to setup basic Authentication and validate the user in SAP APIM proxy Preflow?

[ravi_nagarvwr]

Hello Experts,

I am new to SAP APIM and trying to expose ODATA API through SAP APIM.

Through the SAP Developer community & and other blogs, I have created an API Proxy, and it's working fine.

However, an API is accessible to everyone. anyone who has the API Proxy URL can access it.

I want to set up basic authentication for my API Proxy.

Can you please help me how I can achieve that?

Thanks,

Ravi

Hi Sriprasad,

I have followed this blog till the end (Step 14), but I am getting an error:

{
    "fault":{
        "faultstring":"Failed to resolve API Key variable request.header.APIKey",
        "detail":{
            "errorcode":"steps.oauth.v2.FailedToResolveAPIKey"
        }
    }
}

Please let me know what should I do!
