I tested this out on a site that was on a version that is higher than 19.1:

First I checked what version my site was on by going to https://mycommunitystagesite.com/status/version (replaced mycommunitystagesite with my community stage site's domain name) -- the site I was using was on 19.2 (19.2-release r1905141529).

After I confirmed my site was on 19.2, I added an endpoint to test out this functionality with. I went to Studio > Endpoints tab and created an endpoint named "test-request-body-json" with content type set to "application/json" and this Freemarker logic: 

 

<#if ("POST" == http.request.method)>
  <#assign requestBody = http.request.body?trim />
  <#if requestBody?starts_with("{")>
    <#assign requestBodyObj = utils.json.fromJson(requestBody) />
{ "testValue": "${requestBodyObj.test}" } 
  </#if>
</#if>

 

I then issued an HTTP POST to the endpoint with a JSON payload that it expects to deal with (replaced the URL with the correct one for the endpoint I just created):

 

curl -X POST \
  https://mycommunitystagesite.com/plugins/custom/mycompany/mycommunity/test-request-body-json \
  -H 'Content-Type: application/json' \
  -d '{ "test": "test value" }'

 

I got back the following response when I made that call:

 

HTTP/1.1 200
status: 200

I hope that helps you get things sorted. If you find you are on a version that is lower than 19.2, you can open a support case to request an upgrade to the stage site.

Hi DougS. With the code that you provided, we figured out that when the webhook is sent to our endpoint, initial if condition and the second line to get the request body is working, but this statement in your code

 

 

    <#assign requestBodyObj = utils.json.fromJson(requestBody) />

 

 

doesn't seem to be working and after putting the check for if the body has_content we got to know that in the POST request something is coming to our endpoint but when I'm trying to get it in the restadmin call, nothing seems to set in my metadata where I'm trying to set the request body or any value in the object which comes in the body. I read in this article https://developer.khoros.com/khoroscaredevdocs/docs/working-with-webhooks that 

requestBody: The entire body of the request, read as a UTF8-encoded string

and based on this when I'm getting the request body in my variable I also tried putting ?('utf-8') but that also didn't help. Is there something that I'm missing?

Below is my endpoint code -

 

 

<#attempt>
	<#assign alpha = http.request.body?trim?('utf-8') />  
		<#if alpha?? && alpha?has_content && alpha?is_string >
			<#assign alpha = alpha?eval />
            <#assign updateProfile = restadmin('/users/sso_id/id/settings/name/profile.cert_info/set?value=L1 ${alpha.id}') />
          <#elseif alpha?? && alpha?has_content && alpha?is_hash >
			<#assign updateProfile = restadmin('/users/sso_id/id/settings/name/profile.cert_info/set?value=L2') />
          <#else>
		  	<#assign updateProfile = restadmin('/users/sso_id/id/settings/name/profile.cert_info/set?value=L3') />
        </#if>
  <#recover>
  	<#assign updateProfile = restadmin('/users/sso_id/id/settings/name/profile.cert_info/set?value=LEVEL4') />
</#attempt>

 

 

 

Also for an example, in the webhook documentation from where we are calling our endpoint, something like this is what we are supposed to get in the request body -

{
  "id": "628fcaa9-cfd3-4a9b-aa62-9973ac938ad6",
  "organization_id": "a0d325d9-d8cb-466f-b515-c767949f7e9a",
  "event_type": "badge.created",
  "occurred_at": "2014-04-01T14:41:00Z"
}
