Getting error in setting Transdirect Shipping sender APi code - php

Question

I am trying to implement transdirect.com shipping set sender API to my website but i am getting error i don't know what is the main cause of it.
here is the snippet::
$params = array(
'session' => $session,
'postcode' => '2164',
'name' => 'abc',
'company'=>'abc',
'email' => $email ,
'phone' => '4561237',
'streetName' => 'abcStreet',
'streetNumber' => '28',
'streetType' => 'St',
'suburb' => 'JHONFEILD',
'state' => 'NSW',
'pickupDate' => date( 'Y-m-d' ),
'pickupTime' => '1-4pm',
'hydraulicGate' =>'false'
);
$query = http_build_query($params);
$query = 'http://transdirect.com.au/api/v2/booking/sender?'.$query;
$result = json_decode( curl_sender( $query, $session, $email, $arg = 'sender') );
// curl_sender method::
function curl_sender( $url, $session, $email, $arg ) {
if ( $arg == 'sender' ) {
$datastring = "postcode=2164&name=Tara Trampolines&company=abc&email=".$email."&phone=0280049375&streetName=Unit 4/28 Victoria St&streetNumber=28&streetType=St&suburb=SMITHFIELD&state=NSW&pickupDate". date( 'Y-m-d' )."&pickupTime=1-4pm&hydraulicGate=false";
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $datastring);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data1 = curl_exec( $ch );
curl_close( $ch );
return $data1;
}
I am getting:
stdClass Object (
[message] => Must be authenticated-please create a session first.
[code] => 403
)
Here is the link from we have implemented the api::
http://transdirect.com.au/api/v2/documentation
please specify how we can authenticate each method.
Any help will be appreciable, Thanks in advance.

Answer 1

You've to create a valid session before you requesting the API.
Create the session:
$credentials = array(
'email' => 'test#example.com',
'password' => 'secret'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $credentials);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);
Take a look at the session part: http://transdirect.com.au/api/v2/documentation
You can't mix the session creation process and the real API request.
Create session
Create API request with this session from step 1.
I'm not sure but I think you don't have to use the valid session as any parameter.
The documentation says only create a valid session, there is no parameter specified to append the session, so creation is maybe enough.
This is maybe very important for you:
Confirm booking with any special instructions etc. Once the booking is
confirmed your session is cleared and you will need to
re-authenticate.
