Hi,

I have requirement to call external rest API(which is not exposed on internet https) which is deployed on our network.

I need to pass crm form input data (json format) to this external service and it will return response in json format.

The response should be show in crm ideally html grid and when click on selected record the data should be populate on crm form fields.

Currently using crm 365 online 8.2.2 version.

What will be the best approach to achieve this functionality.

Hi All,

Thanks for your reply.

Mahender,

The external API serves for other systems as well and it will not be possible to deploy on Azure.

If this is the case how to achieve this functionality.

Please let me know if anybody came across this kind of requirement.

Thanks.

Hi Naveen,

You can't communicate Dynamics CRM to your private api hosted on your network because there should be somehow it should be accessible to CRM, only option is the have your api hosted on the Azure and you can try to communicate as suggested by Aric.

You can start looking here: docs.microsoft.com/.../api-management-using-with-internal-vnet

Hi Naveen,

Aric already given an example of calling rest api.Here is another reference, please have a look.

community.dynamics.com/.../786117

var ajax = new XMLHttpRequest();

var url = 'maps.googleapis.com/.../json{' + searchString + '}&types=address&language=en&crossDomain=true&key=[ourkey]';

ajax.open("GET", url, true);

ajax.onload = function () {

var response = JSON.parse(ajax.responseText);

if (!response || !response.results || !response.results[0]) {

alert(response.error.message);

return;

}

};

ajax.send();

Hi Naveen,

I have done this with JavaScript/jQuery and an Azure Api.

You would call it the following way (you can manipulate the below as needed):

var _retrieveCategories = function () {

var urlPath = "xyz.azurewebsites.net/.../GetCategories";

$.ajax({

url: urlPath,

type: "GET",

dataType: "json",

async: false,

crossDomain: true,

success: function (data, textStatus, xhr) {

return JSHelper.toJson(data);

},

error: function () {

}

})

.done(function (data, status, jqxhr) {

});

}

To pass authentication information you can set the authorization property on the above code, or you can also set CORS and set it to the Dynamics Url, so that it is only accessible from there.

Hope this helps.

Hi Goutam,

The external service hosted on secured https and it should't be public.

In this case how we can communicate to this rest api from crm 365 online?

Any work around?

Thanks,

Yadav

Hi Naveen,

Seems this is not possible , you need to host your services in the WEB in addition you service should be "https" . You can not pass information from secure url content to unsecure url . You will get below error.
