is it possible to make a Secured Webservice call from Microsite to other system? I am referring to outbound request when I am trying to call a secured web service of a third party system from a microsite. The third party has shared their client id and secret. However i am not able to hit their service using HTTPPOST2 method as below:
UIButtons'Client_Secret_Here','frms_tid','123232','frms_appid','SFMC','frms_source','SFMC','frms_region','TSJ1','frms_transactiontimestamp' ,'2017-07-24 14:14:31.794')=%% But i am getting an error 400 bad request.
I reached out to salesforce team and they said "you need a CORS exception to allow a cross site reference for the web service".
I am not sure what CORS exception in and how is it relevant here. Will i have to use this CORS exception or is there any other way of making a secured web service call from microsite
