The currentPage().getParameters() can read GET pagams, and also reads POST body only if the header Content-Type = application/x-www-form-urlencoded

However, when the Content-Type changes to application/json, I cannot read incoming JSON, nothing in the keySet(). Here is the code I use to read

Map<string, string> requestText = (Map<string, string>)ApexPages.currentPage().getParameters();

The external application uses application/json in header and there is no way to influence that. Also, no way to do Oauth with that app.

I'm grateful for your ideas

    Are you aiming to build a headless API that is exposed to the unauthenticated internet? – David Reed♦ Jul 25 '19 at 11:41
  • I want the webhook of KanbanFlow.com to update records on salesforce. i haven't completely figured out their security yet.. out of my depth to be honest.. now i am not certain what the kanban server sends (above observations were tested through POSTman, as I was unable to read any data from the server, my class does register the request, but that's it - no body) I'll do a bit more reading.. just wanted some pointers.. – Dextersecret Jul 25 '19 at 12:50

    Security - From KanbanFlow interface doc Each webhook has an associated secret you can use to verify that the request came from KanbanFlow. The request made to your URL endpoint will contain a special header called X-KanbanFlow-Signature. The signature is a HMAC-SHA256 hex digest of the payload using the secret as the key. Exactly how to verify the signature depends on your platform . You can code this verification into your Apex class with @RestResource – identigral Jul 25 '19 at 17:01

Visualforce does not support reading other types of payloads. Instead, you can write an Apex class that uses @RestResource, then expose that class by adding it to the Guest profile for your Site. See Quick Tip – Public RESTful Web Services on Force.com Sites for more information on how this works.

  • and i was hoping it's going to be as easy as reading GET params.. Thanks, I'll give it a read. Still early days of rest, finding my footing.. If it's too complicated, I may just make an intermediate json server to convert JSON to url params, as i only need 2 values. – Dextersecret Jul 25 '19 at 12:54
  • @VladimirMironov It's really easy, just a few lines of code. The blog post has everything you need, and it's only about a five minute read or so. – sfdcfox Jul 25 '19 at 13:07
  • It worked! Beautiful JSON in the end. Thank you Brian! – Dextersecret Jul 25 '19 at 15:52
