This library uses PHP 7.1+.
To use the UPS API, you have to request an access key from UPS. For every request, you will have to provide the Access Key, your UPS User ID and Password.
It is recommended that you install the PHP UPS API library through composer. To do so, run the Composer command to install the latest stable version of PHP UPS API:
$ composer require gabrielbull/ups-api
If not using composer, you must also include these libraries: Guzzle, Guzzle Promises, [Guzzle PSR7] (https://github.com/guzzle/psr7), PHP-Fig PSR Log, and PHP-Fig HTTP Message.
The Address Validation Class allow you to validate an address at street level. Suggestions are given when address is invalid.
Note: UPS has two Address Validations. This is Street Level option, which includes all option of the normal Address Validation class and adds street level validation.
Currently, only US & Puerto Rico are supported.
$address = new \Ups\Entity\Address();
$address->setAttentionName('Test Test');
$address->setBuildingName('Test');
$address->setAddressLine1('Address Line 1');
$address->setAddressLine2('Address Line 2');
$address->setAddressLine3('Address Line 3');
$address->setStateProvinceCode('NY');
$address->setCity('New York');
$address->setCountryCode('US');
$address->setPostalCode('10000');
$xav = new \Ups\AddressValidation($accessKey, $userId, $password);
$xav->activateReturnObjectOnValidate(); //This is optional
try {
$response = $xav->validate($address, $requestOption = \Ups\AddressValidation::REQUEST_OPTION_ADDRESS_VALIDATION, $maxSuggestion = 15);
} catch (Exception $e) {
var_dump($e);
}
In the code above $xav->activateReturnObjectOnValidate()
is completely optional. Calling this method will cause
AddressValidation::validate()
to return an AddressValidationResponse
object. If you do not call this method, validate
continues to function as it has previously. If you do not call this method, a single object with either the matched
validated address, or the first candidate address if the address is ambiguous, will be returned.
The AddressValidationResponse object provides a number of methods to allow you to more easily query the API response to
determine the outcome. Continuing the example from above, returning an AddressValidationResponse
object will allow
you to be a bit more specific with how you handle the various outcomes:
if ($response->noCandidates()) {
//Do something clever and helpful to let the use know the address is invalid
}
if ($response->isAmbiguous()) {
$candidateAddresses = $response->getCandidateAddressList();
foreach($candidateAddresses as $address) {
//Present user with list of candidate addresses so they can pick the correct one
}
}
if ($response->isValid()) {
$validAddress = $response->getValidatedAddress();
//Show user validated address or update their address with the 'official' address
//Or do something else helpful...
}
Address Validation parameters are:
address
Address object as constructed in examplerequestOption
One of the three request options. See documentation. Default = Address Validation.maxSuggestion
Maximum number of suggestions to be returned. Max = 50
The Simple Address Validation Class allow you to validate less extensive as the previous class. It returns a quality score of the supplied address and provides alternatives.
Note: UPS has two Address Validations. This is the Simple option.
Currently, only US & Puerto Rico are supported.
$address = new \Ups\Entity\Address();
$address->setStateProvinceCode('NY');
$address->setCity('New York');
$address->setCountryCode('US');
$address->setPostalCode('10000');
$av = new \Ups\SimpleAddressValidation($accessKey, $userId, $password);
try {
$response = $av->validate($address);
var_dump($response);
} catch (Exception $e) {
var_dump($e);
}
Simple Address Validation parameters are:
address
Address object as constructed in example
The QuantumView Class allow you to request a Quantum View Data subscription.
$quantumView = new Ups\QuantumView($accessKey, $userId, $password);
try {
// Get the subscription for all events for the last hour
$events = $quantumView->getSubscription(null, (time() - 3600));
foreach($events as $event) {
// Your code here
echo $event->Type;
}
} catch (Exception $e) {
var_dump($e);
}
QuantumView parameters are:
name
Name of subscription requested by user. If null, all events will be returned.beginDateTime
Beginning date time for the retrieval criteria of the subscriptions. Format: Y-m-d H:i:s or Unix timestamp.endDateTime
Ending date time for the retrieval criteria of the subscriptions. Format: Y-m-d H:i:s or Unix timestamp.fileName
File name of specific subscription requested by user.bookmark
Bookmarks the file for next retrieval.
If you provide a beginDateTime
, but no endDateTime
, the endDateTime
will default to the current date time.
To use the fileName
parameter, do not provide a beginDateTime
.
The Tracking Class allow you to track a shipment using the UPS Tracking API.
$tracking = new Ups\Tracking($accessKey, $userId, $password);
try {
$shipment = $tracking->track('TRACKING NUMBER');
foreach($shipment->Package->Activity as $activity) {
var_dump($activity);
}
} catch (Exception $e) {
var_dump($e);
}
Tracking parameters are:
trackingNumber
The package’s tracking number.requestOption
Optional processing. For Mail Innovations the only valid options are Last Activity and All activity.
$tracking = new Ups\Tracking($accessKey, $userId, $password);
try {
$shipment = $tracking->trackByReference('REFERENCE NUMBER');
foreach($shipment->Package->Activity as $activity) {
var_dump($activity);
}
} catch (Exception $e) {
var_dump($e);
}
Tracking parameters are:
referenceNumber
The ability to track any UPS package or shipment by reference number. Reference numbers can be a purchase order number, job number, etc. Reference Number is supplied when generating a shipment.requestOption
Optional processing. For Mail Innovations the only valid options are Last Activity and All activity.
$tracking = new Ups\Tracking($accessKey, $userId, $password);
$tracking->setShipperNumber('SHIPPER NUMBER');
$beginDate = new \DateTime('2016-01-01');
$endDate = new \DateTime('2016-01-31');
$tracking->setBeginDate($beginDate);
$tracking->setEndDate($endDate);
try {
$shipment = $tracking->trackByReference('REFERENCE NUMBER');
foreach($shipment->Package->Activity as $activity) {
var_dump($activity);
}
} catch (Exception $e) {
var_dump($e);
}
The parameters shipperNumber, beginDate and endDate are optional. Either of the parameters can be set individually. These parameters can help to narrow the search field when tracking by reference, since it might happen that the reference number used is not unique. When using tracking by tracking number these parameters are not needed since the tracking number is unique.
The Rate Class allow you to get shipment rates using the UPS Rate API.
$rate = new Ups\Rate(
$accessKey,

The Shipping class allows you to register shipments. This also includes return shipments.
The shipping flow consists of 2 steps:
- Confirm: Send information to UPS to get it validated and get a digest you can use to accept the shipment.
- Accept: Finalise the shipment, mark it as it will be shipped. Get label and additional information.
Please note this is just an example. Your use case might demand more or less information to be sent to UPS.
In the example $return
is used to show how a return could be handled.
// Start shipment
$shipment = new Ups\Entity\Shipment;
// Set shipper
$shipper = $shipment->getShipper();
$shipper->setShipperNumber('XX');
$shipper->setName('XX');
$shipper->setAttentionName('XX');
$shipperAddress = $shipper->getAddress();
$shipperAddress->setAddressLine1('XX');
$shipperAddress->setPostalCode('XX');
$shipperAddress->setCity('XX');
$shipperAddress->setStateProvinceCode('XX'); // required in US
$shipperAddress->setCountryCode('XX');
$shipper->setAddress($shipperAddress);
$shipper->setEmailAddress('XX');
$shipper->setPhoneNumber('XX');
$shipment->setShipper($shipper);
// To address
$address = new \Ups\Entity\Address();
$address->setAddressLine1('XX');
$address->setPostalCode('XX');
$address->setCity('XX');
$address->setStateProvinceCode('XX'); // Required in US
$address->setCountryCode('XX');
$shipTo = new \Ups\Entity\ShipTo();
$shipTo->setAddress($address);
$shipTo->setCompanyName('XX');
$shipTo->setAttentionName('XX');
$shipTo->setEmailAddress('XX');
$shipTo->setPhoneNumber('XX');
$shipment->setShipTo($shipTo);
// From address
$address = new \Ups\Entity\Address();
$address->setAddressLine1('XX');
$address->setPostalCode('XX');
$address->setCity('XX');
$address->setStateProvinceCode('XX');
$address->setCountryCode('XX');
$shipFrom = new \Ups\Entity\ShipFrom();
$shipFrom->setAddress($address);
$shipFrom->setName('XX');
$shipFrom->setAttentionName($shipFrom->getName());
$shipFrom->setCompanyName($shipFrom->getName());
$shipFrom->setEmailAddress('XX');
$shipFrom->setPhoneNumber('XX');
$shipment->setShipFrom($shipFrom);
// Sold to
$address = new \Ups\Entity\Address();
$address->setAddressLine1('XX');
$address->setPostalCode('XX');
$address->setCity('XX');
$address->setCountryCode('XX');
$address->setStateProvinceCode('XX');
$soldTo = new \Ups\Entity\SoldTo;
$soldTo->setAddress($address);
$soldTo->setAttentionName('XX');
$soldTo->setCompanyName($soldTo->getAttentionName());
$soldTo->setEmailAddress('XX');
$soldTo->setPhoneNumber('XX');
$shipment->setSoldTo($soldTo);
// Set service
$service = new \Ups\Entity\Service;
$service->setCode(\Ups\Entity\Service::S_STANDARD);
$service->setDescription($service->getName());
$shipment->setService($service);
// Mark as a return (if return)
if ($return) {
$returnService = new \Ups\Entity\ReturnService;
$returnService->setCode(\Ups\Entity\ReturnService::PRINT_RETURN_LABEL_PRL);
$shipment->setReturnService($returnService);
}
// Set description
$shipment->setDescription('XX');
// Add Package
$package = new \Ups\Entity\Package();
$package->getPackagingType()->setCode(\Ups\Entity\PackagingType::PT_PACKAGE);
$package->getPackageWeight()->setWeight(10);
$unit = new \Ups\Entity\UnitOfMeasurement;
$unit->setCode(\Ups\Entity\UnitOfMeasurement::UOM_KGS);
$package->getPackageWeight()->setUnitOfMeasurement($unit);
// Set Package Service Options
$packageServiceOptions = new \Ups\Entity\PackageServiceOptions();
$packageServiceOptions->setShipperReleaseIndicator(true);
$package->setPackageServiceOptions($packageServiceOptions);
// Set dimensions
$dimensions = new \Ups\Entity\Dimensions();
$dimensions->setHeight(50);
$dimensions->setWidth(50);
$dimensions->setLength(50);
$unit = new \Ups\Entity\UnitOfMeasurement;
$unit->setCode(\Ups\Entity\UnitOfMeasurement::UOM_CM);
$dimensions->setUnitOfMeasurement($unit);
$package->setDimensions($dimensions);
// Add descriptions because it is a package
$package->setDescription('XX');
// Add this package
$shipment->addPackage($package);
// Set Reference Number
$referenceNumber = new \Ups\Entity\ReferenceNumber;
if ($return) {
$referenceNumber->setCode(\Ups\Entity\ReferenceNumber::CODE_RETURN_AUTHORIZATION_NUMBER);
$referenceNumber->setValue($return_id);
} else {
$referenceNumber->setCode(\Ups\Entity\ReferenceNumber::CODE_INVOICE_NUMBER);
$referenceNumber->setValue($order_id);
}
$shipment->setReferenceNumber($referenceNumber);
// Set payment information
$shipment->setPaymentInformation(new \Ups\Entity\PaymentInformation('prepaid', (object) ['AccountNumber' => $shipper->getShipperNumber()]));
// Ask for negotiated rates (optional)
$rateInformation = new \Ups\Entity\RateInformation;
$rateInformation->setNegotiatedRatesIndicator(1);
$shipment->setRateInformation($rateInformation);
// Get shipment info
try {
$api = new Ups\Shipping($accessKey, $userId, $password);
$confirm = $api->confirm(\Ups\Shipping::REQ_VALIDATE, $shipment);
var_dump($confirm); // Confirm holds the digest you need to accept the result
if ($confirm) {
$accept = $api->accept($confirm->ShipmentDigest);
var_dump($accept); // Accept holds the label and additional information
}
} catch (\Exception $e) {
var_dump($e);
}
If you wanted to create a printable file from the UPS Shipping label image data that came back with $accept, you would use something like the following:
$label_file = $order_id . ".gif";
$base64_string = $accept->PackageResults->LabelImage->GraphicImage;
$ifp = fopen($label_file, 'wb');
fwrite($ifp, base64_decode($base64_string));
fclose($ifp);
For the Shipping confirm
call, the parameters are:
- $validation A UPS_Shipping::REQ_* constant (or null). Required
- $shipment Shipment data container. Required
- $labelSpec LabelSpecification data. Optional
- $receiptSpec ShipmentRequestReceiptSpecification data. Optional
For the Shipping accept
call, the parameters are:
- $shipmentDigest The UPS Shipment Digest received from a ShipConfirm request. Required
The Shipment Service Options class allows you to register shipments additional options. This also includes.
- Add or Modify email notifications: Manage updates for this shipment.
- Saturday Commericial: Get weekend delivery of your shipment.
- Deliver only to receiver's address: Do not reroute for customer pickup at a UPS location.
- UPS Carbon Neutral Shipments Thanks for offsetting the environmental impact of your shipment! : at a nominal fee for domestic and international shipments.
In the example ShipmentServiceOptions class is used to show how a Shipment Additional Option can be added to Shipment.
// Start shipment
$shipment = new Ups\Entity\Shipment;
// Create Shipment Service Options Class
$shipmentOptions = new Ups\Entity\ShipmentServiceOptions;
// Setting the Carbon Neutral Additional Option, you can set your desired one.
$shipmentOptions->setUPScarbonneutralIndicator();
// Set Shipment Service Options Class
$shipment->setShipmentServiceOptions($shipmentOptions);
All constructors take a PSR-3 compatible logger.
Besides that, the main UPS class has a public method setLogger
to set it after the constructor ran.
Requests & responses (including XML, no access keys) are logged at DEBUG level. At INFO level only the event is reported, not the XML content. More severe problems (e.g. no connection) are logged with higher severity.
Example using Monolog
// Create logger
$log = new \Monolog\Logger('ups');
$log->pushHandler(new \Monolog\Handler\StreamHandler('logs/ups.log', \Monolog\Logger::DEBUG));
// Create Rate object + insert logger
$rate = new Ups\Rate($key, $username, $password, $useIntegration, $log);
