As part of our first operational use of the API, I need to update two fields dynamically. For trials, I am using php cUrl, modeled on your sample application. I have no problems with GET, but PUT leaves me baffled.

Each time I run the script, the target fields are not changed - but the membership of the target contact goes from "active" to "membership not allocated".

Clearly my code is doing this: but how/why? Can anyone give me a clue as to what is happening?

Also, my debugging script shows a result JSON containing all the target contact's data. Is this as it should be? And can it be prevented (unnecessary data traffic, etc.)?

My cUrl code is (sorry about the bad formatting below):

$accountUrl = "https://api.wildapricot.org/v2/accounts/[account]/Contacts/";
$queryParams = array(
'Id' => $contact,
'Field values' => array(
0 => array(
'FieldName' => "fieldname1",
'Value' => 'XXXXX'
),
1 => array(
'FieldName' => "fieldname2",
'Value' => 'XXXXXX'
)
)
);
$url = $accountUrl.$contact;
$verb = "PUT";

$ch = curlinit();
$headers = array(
'Authorization: Bearer ' . $token,
'Content-Type: application/json'
);
curlsetopt($ch, CURLOPTURL, 'https://api.wildapricot.org/v2/accounts/[account]/Contacts/[contact]');
curlsetopt($ch, CURLOPTHTTPHEADER, $headers);
curlsetopt($ch, CURLOPTCUSTOMREQUEST, $verb);
if ($queryParams) {
$jsonData = jsonencode($queryParams);
curlsetopt($ch, CURLOPTPOSTFIELDS, $jsonData);
}

curlsetopt($ch, CURLOPTRETURNTRANSFER, true);
$jsonResult = curlexec($ch);
if ( !$jsonResult ) {
echo curlerrno($ch) . ': ' . curlerror($ch);
}
curlclose($ch);
