ExactTarget - Sending TriggeredSend Email With Data Extension

Question

I am new to Exact Target API and I am using the FuelSDK for PHP. I already have my data extension (created using TriggeredSendDataExtension template) with an email field that is linked to all subscribers' emails. My data extension's primary key is "My_ID" which are populated with unique strings.

This is my code:

 $sendTrigger = new ET_TriggeredSend();
 $sendTrigger->props = array('CustomerKey' => 'My_Trigger');
 $sendTrigger->authStub = $this->myclient;
 $sendTrigger->subscribers = array(array("EmailAddress" => "customer@email.com", "SubscriberKey" => "customer@email.com", "My_ID" => "someUniqueString"));
 $response = $sendTrigger->send();

But I always get this error response:

[ErrorCode] => TriggeredSendSubscriberProcessingError 
[ErrorDescription] => Error Code: 19 - No value was provided for required data extension field My_ID. 

Can anyone please enlighten me?

Answer 1

MY_ID should be in the Subscribers.Attribute array, not on the Subscribers array itself.

Take a look ET's example on the Send TriggeredSend Email page:

I find the SOAP envelopes most helpful. It's at the bottom.

Answer 2

95% of time this error occurs, is because the API is not passing a value for the two default and required fields, email address and subscriber key. got those in there?

Answer 3

EX props (for Ruby, I'm not a PHP dev):

sendTrig.props = [{
"CustomerKey" => "TRIGGERED_EMAIL_NAME", 
"Subscribers" => {
    "EmailAddress"=>"example@email.com", 
    "SubscriberKey" => "example@email.com", 
    "Attributes" => [{
            "Name"=>"EMAIL_ADDRESS", 
            "Value"=> "example@email.com"
            }]
    }
}]

EmailAddress, SubscriberKey, and EMAIL_ADDRESS all need to be set and have the same value for the email to be sent.
