DougS were there any methods added since 2016 that would allow to read a JSON payload in a request body via FreeMarker? Have the same scenario like OP. Sending data that way is quite common for third party API's when sending data via webhook-functionality, e.g. sending back data to some endpoint/webhook after something was done on their platform...
Hi luk ,
Unfortunately we have not added a way to do this yet, but I have taken to heart how long it has been and have added a pull request to add in support for parsing the request body (named http.request.body, in endpoints only) and a utils object for converting to/from a JSON string to a Freemarker hash (utils.json.toJson(hash) and utils.json.fromJson(string)).
I'll update this post once I know what version of the Community product it will go into.
Thanks,

DougS that's awesome, thank you very much! Any chance support or professional services could merge that PR into a specific instance? Could you provide the (internal) PR number so I could refer it with support/PS? Currently working on a project where that functionality is needed rather urgently... was planning to create a microservice that would receive the incoming request, extract the request body and forward it to Lithium/FreeMarker in way it can understand.
With that new information this seems kind of unnecessary though, of course that depends on the answer if support/PS can add the new FreeMarker functionality ahead of the official release for a specific client?
Also great to have "official" tools to parse JSON, always had to rely on a custom JSON-parser method in FreeMarker, which was less than ideal, using ?eval and a bunch of ?replace()'s!
Thanks again!
Hey DougS ,
Is there any update regarding what you have mentioned in your comment because I couldn't find anything related to "get request body in the endpoint" in the current 19.4 and 19.5 release notes. I am also stuck with the same issue mentioned above about how to get payload of a Webhook's POST request in an endpoint. If you can provide any update on this then it will be really helpful.
Thanks in advance.
We actually added this back in 19.2, but looks like it didn't make it into any release notes or into our Freemarker documentation -- I will make sure this gets added to our Freemarker documentation. In the meantime, you should be able to do this to parse JSON out of the request body:
<#assign requestBody = http.request.body />
<#assign requestBodyObj = utils.json.fromJson(requestBody) />
(Please note that the http.request.body object will only work when used in Endpoints -- it will throw an exception if used in a component on a community page)

Hey DougS . Thanks for replying. I tried what you have mentioned above and that doesn't seem to be working when I am sending a webhook to my endpoint where I'm trying to get the request body. I basically just wrote your above-mentioned code and then I'm taking the requestBodyObj and putting it in a restadmin call as a variable to update a metadata field but nothing is getting set over there. Is there a different way to do that with your given code?
