[SalesForce] Rest Request to insert/update record in external system

Found a post by @superfell - "You can't insert multiple rows in a single call in the rest api, you need to use the bulk api." https://stackoverflow.com/questions/5898590/rest-multiple-insert

REST API means that you can use 'GET', 'POST', 'PATCH' or 'DELETE' as HTTP methods for your requested resource. These methods correspond to what you're trying to achieve. GET = describe, POST = insert, PATCH = update, DELETE = delete. Here's an example of how to insert a new Account using the POST method:

POST /services/data/v31.0/sobjects/Account HTTP/1.1
Host: na15.salesforce.com
User-Agent: Guzzle/4.1.6 curl/7.30.0 PHP/5.4.24
Authorization: Bearer 00Di000000xxxxxx
Accept: application/json
Content-Type: application/json
Content-Length: 24

{"Name":"New Account"}
