Passing variable / parameter to external web resource

(0) ShareShare
ReportReport
Posted on by dynaman365 30

Hi there

I have successfully created a Web Resource in our Sales Trial which displays an external web page on the Account screen.

When calling the web resource I need to pass a variable so a query can be run on the page and the correct data returned.

EG pass account code which will be looked up in our database, the returning data will be displayed on the page and shown in the Account screen.

Am I using the correct terminology? and what methods are available to achieve this please?

Could I pass the parameter in the URL? If so how to dynamically add the parameter?

This article references the Custom Data Parameter column in the web resource dialogue, but where is that located?

Sample: Pass multiple values to a web resource through the data parameter (model-driven apps) - Power Apps | Microsoft Docs

Most grateful for your assistance.

Paul

    Hi dynaman365,

    How do you call the web resource, type address in the bowser or open it with Client API?

    Hi Steve - thanks for your reply

    I've inserted a web resource onto the form and successfully called an external html page which is great.  I need to pass the account name for example when calling the external page. I've just discovered if I double click on the form in the editor I get the below image:

    I've ticked the box to pass identifiers as parameters. I now need to check to see what is being passed and display it back to prove that I'm receiving them on the external html page.  Any pointers to achieve that?

    Hi dynaman365,

    A quick question:  Where are your account name from? Is it a static value or it comes from the Account entity's form of the CRM?

    Hi Steve

    Yes I'd like to take the account name or another field from the account entities form and pass it in the URL.  Is that possible?

    Kind regards

    I've managed to pass some static variables in the URL this morning. Now I need to figure out how to pass a variable, like the account name or some other value.

    Hi dynaman365,

    You can get form context in the web resource, and then get your account name from the Account's from. Please refer to this blog:

    Hi Steve - great link. Some very helpful content there.

    I dont think this helps me achieve what I need in this instance, but perhaps I've misunderstood.

    What I need to do is somehow pass a parameter along with the call to the external web resource EG  

    www.mywebsite.com/?accountName=ABC123

    The account code will then be looked up in our database and our page loaded into a form on the account page.

    Does that seem feasible?

    If it is not possible to pass a parameter along with the call to the external web resource, is it possible to define the parameter using one web resource, then create an action to call the external web resource using that defined parameter?

    EG, look up the account name "ABC123", use script "callExternalWebResource.js" to call another web resource "mysite.com/externalWebResource.html"

    Hi dynaman365,

    Please try this:

    1. Get the account name from the Account's form in your html type web resource, as shown in previous blogs.

    2. Then send ajax request with your URL www.mywebsite.com/?accountName=[account name got from step1] in your web resource. Reference: Access external web service using HTML Web Resource - Microsoft Dynamics CRM Forum Community Forum

    3. Finally get the data returned from ajax request and add it your web resource.

    Hi Steve

    Thanks so much for your assistance on this one.  I have finally got something working!  on_load of the Accounts form it runs an html web resource which contains some javascript which calls an external web page and appends the accountID to the url.  The external page then looks up relevant meta data related to this record and displays it in the web resource.

    I think you are correct that it requires an Ajax request as currently the web page doesn't actually appear until the page is reloaded.

    In case it helps anyone else this is the code I used:

     

    var myVarName = formContext.getAttribute("requiredFieldName").getValue();

var url = "www.example.com/?data="   myVarName;

var tag = document.createElement("object");
tag.setAttribute( "type", "text/html");
tag.setAttribute( "data", url );
tag.setAttribute( "width", "600px");
tag.setAttribute( "height", "600px");
console.log( tag );
document.body.appendChild( tag );

    The key was formContext.getAttribute to get the table field required from the form.

    I then used some javascript to call the web resource and build it into an HTML page.

    Kind regards
