CI Client Parsing JSON

Your best bet is to have server A send a POST to Server B with the JSON string included in a field.

Server A sends a POST request to Server B with a field of say,

PHP Code:

$payload = json_encode($myData); 


Then on Server B at your endpoint, you grab it using either

PHP Code:

$_POST["payload"] 


or

PHP Code:

$this->input->("post");
