XML based D365 F&SCM(AX7) custom web API

Hi,

A vendor has requested us to expose an XML based custom D365 F&SCM API.

As far as I know, the D365 F&SCM custom web API works with JSON request/response. Is there a way to natively implement this.

I've thought of a workaround where I will create a HTTP trigger logic app which will take XML request. Then I'll convert this XML request to JSON and pass it to D365 custom web API. I would like to know if there is a better way to achieve this?

Note, the vendor is not able to send us request in any other format so we are bound to work with XML request/response.

I have the same question (0)

Hi Abishek,

What do you mean by custom api? Do you mean custom services? If yes then you can access it as SOAP or json where in soap u can pass xml

Hi, you can develop custom services for finance and operations. When a developer writes a custom service under a service group, the service group is always deployed on two endpoints:

SOAP endpoint

JSON endpoint

Please refer to the MS document about custom service:

Hi Layan, yes we need to create a custom service that the external vendor will use as an API call to communicate to D365 F&SCM. Let me refer the link shared by you. If the soap service can accept the XML request than my job would be done. I'll mark the reply as answer if this works. Thanks for your response!

Hi Abishek,

Yes it should work, I'll be waiting for you come back to us with your findings :)

Btw, you can download a tool called SOAP UI, it might make your testing for the custom service easier.

Thanks,

SOAP is an XML format, therefore the SOAP endpoint can accept XML, but this XML must be in SOAP format. It can't be just any arbitrary XML.

Note that you can use a middle-tier service to transform your XML to either JSON or SOAP.

Hi Layan, I did try out the soap and as mentioned by Martin already, I was not able to comsue the agreed upon schema as request. The XMl we have is not in SOAP format.

Hi Martin, I am planning to have an HTTP trigger based logic app which will accept XML as request. Then I'll convert it to JSON and call the D365 service. Please let me know if there is a better approach to achieve this.

Hi Abishek,

If you can't make your xml in SOAP format directly. Then you'll need a middleware to convert it to json or soap. Logic apps can be an option
