RDynamics

Dynamics 365 Online CRM Web API - Lightweight PHP Connector

Initializing:

$RDynamics = new RDynamics(array(
    "base_url"              => "https://YOUR_CRM_INSTANCE.crm4.dynamics.com",
    "authEndPoint"          => "https://login.windows.net/common/oauth2/authorize",
    'tokenEndPoint'         => 'https://login.windows.net/common/oauth2/token',
    'crmApiEndPoint'        => 'https://YOUR_CRM_INSTANCE.api.crm4.dynamics.com/',
    "clientID"              => "***", 
    "clientSecret"          => "***", 
    'user'                  => '***',
    'pass'                  => '*'
));

Querying contacts:

$contactsResponse = $RDynamics->contacts->select('?$select=fullname');
if($contactsResponse->isSuccess()) {
    // $contactsResponse->getData(); - Return data as array
}
else {
    // $contactsResponse->getErrorMessage(); - Return CRM Web API error message as string
}

Querying contacts (when the number of contacts is more then 5000, you need paging):

$i = 1;
do {
    if((isset($contactsResponse) && $contactsResponse)) {
        $endpoint = $contactsResponse->getNextLink();
        if(!$endpoint) { // no next link defined, exiting
            break;
        }
    }
    else { // first loop
        $endpoint = '?$select=gendercode,fullname';
    }

    $contactsResponse = $RDynamics->contacts->select($endpoint);
    if($contactsResponse->isSuccess()) {
        // $contactsResponse->getData(); - as array
        ++$i;
    }
    else {
       // $contactsResponse->getErrorMessage(); - or ->getError() to get the full error object (with error_code and more)
    }
} while($contactsResponse->getNextLink());

Inserting contact:

$contactsResponse = $RDynamics->contacts->insert(array(
    "emailaddress1"     => "some_test_email"
));

if($contactsResponse->isSuccess()) {
    // $contactsResponse->getGuidCreated(); - Get the GUID of the created entity
}
else {
    // $contactsResponse->getErrorMessage(); - Get the error message as string
}

Updating contact

$contactsResponse = $RDynamics->contacts->update('00000000-0000-0000-0000-000000000000', array(
    "emailaddress1"     => "some_test_email"
));

if($contactsResponse->isSuccess()) {
    // $contactsResponse->getData(); - Get the response data
    // $contactsResponse->getHeaders(); - Get the response headers
}
else {
    // $contactsResponse->getErrorMessage(); - Get the error message as string
}

Deleting contact:

$contactsResponse = $RDynamics->contacts->delete('00000000-0000-0000-0000-000000000000');
if($contactsResponse->isSuccess()) {
    // $contactsResponse->getData(); - Get the response data
    // $contactsResponse->getHeaders(); - Get the response headers
}
else {
    // $contactsResponse->getErrorMessage(); - Get the error message as string
}

Running batch methods (max. 1000 request per batch):

$contactsResponse = $RDynamics->contacts->select('?$top=10');
if($contactsResponse->isSuccess()) {
    $customers = $contactsResponse->getData();
    $batchID = "batch_" . uniqid();
    $payload = '';
    $i = 1;

    foreach($customers as $customer) {
        $customerID = $customer["contactid"];
        $payload .= <<<EOT
--$batchID
Content-Type: application/http
Content-Transfer-Encoding:binary
Content-ID:$i

PATCH https://YOUT_CRM_INSTANCE.crm4.dynamics.com/api/data/v8.1/contacts($customerID) HTTP/1.1
Content-Type: application/json;type=entry

{"ftpsiteurl":"ftp://..."}

EOT;
        ++$i;
    }
    $payload .= "--" . $batchID . "--\n\n";
    $batchResponse = $RDynamics->performBatchRequest($payload, $batchID);

    // $contactsResponse->getData(); - Get the response data
    // $contactsResponse->getHeaders(); - Get the response headers
}
else {
    // $contactsResponse->getErrorMessage(); - Get the error message as string
}
