Call external web service from web resource

Hello,

I'm trying to call a method in a asp.net web api from a web resource using jquery ajax function (I've also tried with xmlhttprequest).

We're using onpremise crm 2016, and this external web api is located in the same server in which crm is installed.

I've tried the same call from another web application I created in the same iis with a different port, and it works fine. But when I deploy it to a web resource (I've even tried from the isv folder inside the crm web app) it fails.

When debugging with IE developer tools in the IE brower in the server, I've getting this message in the console:

XMLHttpRequest: Network Error 0x80070005, Access is denied.

How can I make this work? I've read some articles where other people can do it without doing special configurations and without having to make an action and pass parameters from js to call the external web api from the action.

Thank you.

Hi Vermin,

Share your code so we can understand better about your situation. Usually I will try to invoke my API using postman before I do coding to make sure I'm not miss out the configuration to call my API. Below is the example to calling using jquery ajax.

$.ajax({

url: url,

dataType: "jsonp",

async: true,

type: "GET",

timeout: 120000,

jsonpCallback: "MyCallback",

success: function (data, textStatus, jqXHR) {

//Success action

},

error: function (jqXHR, textStatus, errorThrown) {

//Error action

},

complete: function (jqXHR, textStatus) {

//Complete action

}

});

RE: Call external web service from web resource

Hello. Thank you for your answer.

I knew I could use an action as a bridge to call the asp net web api from it, but I didn't want to do it because one of the functionalities my web resource has is to give the user the functionality to pick a file and upload it to the server from their computers (they don't want to use the built-in Notes). To use actions for this would take me to upload the file to a temporal note to be then taken by the action. Too much executing time, as there is more logic in the server done by the web api.

I'm afraid that if there's no way to call directly from a js web resource to a external web api, I'll have to take out the full functionality to a external form and have it in an i-frame in CRM.

One more thing. Is Process.js supported? It makes use of the javascript namespace MsCrm and from what I know, it's internal and it could change without warning from MS.

RE: Call external web service from web resource

Hi,

You can follow below steps to call external webapi through javascript:

1. Create a custom activity (c#) to call web api and deploy it to CRM

2. Create Custom Action and add the activity (created and deployed in step 1) as a step

3. Call this custom action in your javascript (You can use Process.js to call custom action easily)

Below links may be helpful to you:

Use Process.js:

Hope this helps:)
