I am trying to get Post from wordpress and store into Salesforce Account.

Note : CALLOUT_RESPONSE|[29]|System.HttpResponse[Status=Forbidden, StatusCode=403]

I am getting 403 status code.

I am using an Apex trigger and asynchronous method to perform a callout to the JSON REST API for Wordpress. I continue to receive 500 Internal Server Error responses in my debug log when I edit a Salesforce record, but if I copy/paste the corresponding JSON into the Postman plug-in for Chrome the post is created as expected. Any help is appreciated, thanks!

 

trigger insertPost on Custom_Object__c (after insert, after update) {
    String theIds = '';
    for (Custom_Object__c c : Trigger.new) {
        if (theIds == '')
            theIds = c.Id;
        else
            theIds += '|' + c.Id;
