Error when accessing retail API

(0) ShareShare
ReportReport
Posted on by Rob vanBrandenburg 285

I am trying to access the retail API from a .net class using this example:

community.dynamics.com/.../how-to-access-retail-server-in-managed-code

However I'm getting the error below once it tries to execute

ChannelConfiguration channelConfiguration = await orgUnitManager.GetOrgUnitConfiguration();

Error:
Contoso.Retail.Ecommerce.Publishing.vshost.exe Error: 0 : System.InvalidOperationException: The response payload is a not a valid response payload. Please make sure that the top level element is a valid Atom or JSON element or belongs to 'docs.oasis-open.org/.../data' namespace.
   at Microsoft.OData.Client.Materialization.ODataMaterializer.CreateODataMessageReader(IODataResponseMessage responseMessage, ResponseInfo responseInfo, ODataPayloadKind& payloadKind)
   at Microsoft.OData.Client.Materialization.ODataMaterializer.CreateMaterializerForMessage(IODataResponseMessage responseMessage, ResponseInfo responseInfo, Type materializerType, QueryComponents queryComponents, ProjectionPlan plan, ODataPayloadKind payloadKind)
<-- Rest of stack trace cut -->

Any idea how to troubleshoot this?

    I don't know if we ever got this truly resolved, as the customer decided to go a different route.

    What I did find out is though that you need to 'enable' the channel via code, you will need to execute certain logic against the API from client code in order

    to enable it. I'll see if I can find it and post it here.

    Thanks Sergey. We've gotten a bit further with this. The retail URL was correct, but there were some issues with the setup in D365FO (application secrets etc) - it looks like we are getting close - we just need to get the online store published at this moment.

    Probably the Url you specified for your Retail Server is not correct, can you open yourretailserverurl/Commerce in the browser - what will you see?
