CCDA R2 validator -CORS issue

[Radhika Thota]

Hello, 

 
 we are using validator tool in our ASP.NET web application (ajax call), since 2017 awith below request URL and payload

 $.ajax({
                url: 'https://ett.healthit.gov/ett/api/ccdar2/?validationObjective=C-CDA_IG_Plus_Vocab&referenceFileName=Readme.txt',
                type: 'POST',
                data: formData,
                contentType: false,
                processData: false,
                async: true,
                success: function (result) {
                    fnPassValuesToAPI_success(result);
                },
                error: function (msg) {
                    alert("Faild please try upload again" + msg.responseText); 
                }
            });

From past few months , we are unable to get validation data and getting error when tried to hit the url. As per our investigation , found CORS policy issue

 
 'Access to XMLHttpRequest at 'https://ett.healthit.gov/ett/api/ccdar3/?validationObjective=C-CDA_IG_Plus_Vocab&referenceFileName=Readme.txt' from origin 'http://server' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
 
 and from IE , receiving 'Access denied' issue
 
 please guide to use validator tool in our application as part of our EHR.
 Any help in this regard is very much appreciated.

We have a created a ticket and will look into this.

Have you tried the SITE API? That is what ETT calls, so it's a bit more direct.
https://ccda.healthit.gov/referenceccdaservice/

*form-data*

ccdaFile: <file>

referenceFileName: readme.txt

validationObjective: C-CDA_IG_Plus_Vocab

If you want to use the cures update, add:

curesUpdate: true

Or if you want SVAP 2022, add:

svap2022: true

Thanks,

Dan

still facing  issue even with API:

https://ccda.healthit.gov/referenceccdaservice/

*form-data*

ccdaFile: <file>

referenceFileName: readme.txt

validationObjective: C-CDA_IG_Plus_Vocab

  Access to XMLHttpRequest at 'https://ccda.healthit.gov/referenceccdaservice/' from origin 'https://servername' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

The API is publically accessible. We have tested it from multiple locations and applications w/o issue.

Have you tried testing it in postman, directly?

[Mat Davis]

Thank you very much for your reply regarding the Body type (form-data) and other custom key/value pairs for testing with the referenceccdaservice endpoint

Is there any other source of documentation I can reference by chance?

If not, then that's fine. What you have provided has allowed me to achieve success.

Thanks - Mat

You're welcome.

We have API documentation via swagger here:

https://ccda.healthit.gov/referenceccdaservice/swagger-ui.html#/reference-ccda-validation-controller

And general documentation here in the readme:
