Updating Fields create/update leads endpoint

[Anonymous]

Hi,

I am able to access the create/update fields endpoint.  However, there are certain fields that I am unable to update.  

For example in marketoI have a field called "Phone", but the lead does not update.  Other fields do update, so it is working.  Below is a snippet of my code:

$add_lead_url = "https://***.mktorest.com/rest/v1/leads.json?access_token=". $this->mk_access_token;

echo $add_lead_url;

$email = $entry[11];

$firstName = $entry[1];

$lastName = $entry[2];

$company = $entry[3];

$phone = $entry[10];

$data = array( 

  'action' => 'createOrUpdate', 

  'lookupField' => 'email', 

  'input' => array(array(

    'email' => $email, 

    'firstName' => $firstName, 

    'lastName' => $lastName, 

    'company' => $company, 

  'phone' => $phone

  )
)
);

$options = array(

'http' => array(

    'method'  => 'POST',

    'content' => json_encode($data),

    'header'=> "Content-Type: application/json\r\n" .

          "Accept: application/json\r\n"

),

);

$context  = stream_context_create($options);

$result = file_get_contents($add_lead_url, false, $context); 

Thanks,

Dan

This might be a formatting issue.  I woud try these variations:

'123-456-7890'
'1234567890'

In addition to what Murtza suggested, you may want to check field management to see that the field is not blocked from updates.
