What is the Metadata URL for SAP Jam OData?

[Former Member]

Hi, we are in datacentre 12, and I got sent the following URL for the OData API:

https://jam12.sapjam.com/api/v1/odata

My question is, should there be a metadata endpoint that I can use to add a service reference so that I don't have to hand-code proxy classes?

I.e. Does a URL like this exist?

https://jam12.sapjam.com/api/v1/odata/$metadata

Regards,

Andrew.

Yes, we support the following metadata URL: https://jam12.sapjam.com/api/v1/OData/$metadata

You can see the documentation for that here: SAP Jam Developer Guide

Hi Robert, thanks for the reply.  Your URL is interesting because it shows as "https://jam12.sapjam.com/api/v1/OData/$metadata" but links to "https://developer.sapjam.com/api/v1/OData/$metadata" under the hood .

Anyhow I tried both URL's.  In my web browser they come up fine.  However when I use Visual Studio 2015 and try and add a service reference, I get the following error:

There was an error downloading 'https://jam12.sapjam.com/api/v1/OData/$metadata'.

The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF

Metadata contains a reference that cannot be resolved: 'https://jam12.sapjam.com/api/v1/OData/$metadata'.

The HTTP request was forbidden with client authentication scheme 'Anonymous'.

The remote server returned an error: (403) Forbidden.

If the service is defined in the current solution, try building the solution and adding the service reference again.

I suspect the crux of that error is "(403) Forbidden".  Is it possible I need to supply credentials to connect, or is there a metadata endpoint exposed that does not have security on it and would allow an anonymous request to the metadata URL?

Cheers.

I should also mention, I have been able to successfully connect to and use the SuccessFactors OData API via URL:

https://api10.successfactors.com/odata/v2/$metadata

When I try to "Add Service Reference" on that one, it pops up a box saying "The server needs to authenticate your request. Your credentials will be sent to the server in clear text. Do you want to continue? (Yes/No)", when I say "Yes" it asks for credentials which I enter and it lets me in.

I would expect the SAP Jam one to do the same if it is secured, but the security must be slightly different on it.

Cheers.

Hi Andrew. I've asked one of my team to take a look. I don't currently have VS installed. Hang tight for a bit.

Hi Andrew, we've discovered a few hurdles in getting this to work within Visual Studio.  We are working on a way to get this to work.  We will provide you with the documentation on this once ready.

Thanks,
Adam
