How to Start

1. You need to acquire an access token and a secret
2. Install a client using composer: composer require "covery/client=^1.0.0"

Basic Integration

The first thing you need is to initialize Facade with credentials and transport. To do this, place the following code somewhere close to your application initialization:

Optional (use only for debug):

That's all!

Having completed this procedure, you can now query Covery using Facade::sendEvent, Facade::sendPostback, Facade::makeDecision.

Tech Details

Facade

Covery\Client\Facade is a static wrapper over Covery\Client\PublicAPIClient. If you use dependency injection or other application assembly mechanism, you may prefer not to use Facade, and rather use the client directly.

PSR-3, PSR-4 and PSR7

1. Covery client supports PSR-3 loggers. You may assign them to Facade calling Facade::setLogger or to PublicAPIClient passing a logger as a constructor argument.
2. Covery client code uses PSR-4 autoloader. Just require /vendor/autoload.php.
3. HTTP communication uses PSR-7 HTTP message, so you may extend the client's capabilities as you see fit.

Transports

Covery client may use any class that satisfies Covery\Client\TransportInterface to send requests. Covery client ships with two major implementations:

1. Covery\Client\Transport\Curl - simple PHP curl implementation
2. Covery\Client\Transport\OverGuzzle - adapter over Guzzle HTTP client

Envelopes

Methods sendEvent and makeDecision require envelope as argument. Envelope is a pack of following data:

• SequenceID - Event grouping identifier. Covery will attempt to group events using this field. It is recommended to use userID as a sequence ID. However, Covery requires a long string (6-40 characters) in this field, so you may use md5($userId) as SequenceID for better results.
• Identities - List of identities this event belongs to. For most cases a single Identities\Stub is enough.
• Type - Event type, one of:
  • install - install event
  • registration - registration event
  • confirmation - registration confirmation event, must have the same SequenceID with registration event
  • login - login event, must have the same SequenceID with registration event
  • transaction - payment event, must have the same SequenceID with registration and login events
  • refund - refund event
  • payout - payout event
  • transfer - transfer event
  • kyc_profile - kyc profile event
  • kyc_submit - kyc submit event
  • order_item - order item event
  • order_submit - order submit event
  • document - document event

Envelope specifications are bundled in Covery\Client\EnvelopeInterface.

You may provide the following as envelopes:

1. Own implementations of EnvelopeInterface. For example, your own payment order model may be extended to implement EnvelopeInterface, then you may pass it to sendEvent and/or makeDecision directly.
2. Custom-built Covery\Client\Envelopes\Envelope
3. Envelopes built using Covery\Client\Envelopes\Builder (don't forget to invoke build()!)

Results

1. sendEvent will return integer (may be x64) containing ID of a stored entity on Covery side. You should log it.
2. makeDecision will return Covery\Client\Result object:
   • Call getScore() to obtain score in range [-100, 100]
   • Method isAccept() will return true if Covery did not found fraud in incoming envelope data
   • Method isReject() will return true if Covery found fraud in incoming envelope data

Exception Tree

• Covery\Client\Exception - base exception
  • Covery\Client\EnvelopeValidationException - thrown if envelope failed client side validation
  • Covery\Client\DeliveredException - exception delivered for Covery server
  • Covery\Client\AuthException - authorization exception
  • Covery\Client\IoException - server communication error
  • Covery\Client\TimeoutException - timeout

Error loggers

• \Covery\Client\Loggers\VarDumpLogger - simple var_dump logger
• \Covery\Client\Loggers\FileLogger - writing errors to a file
• You can also write your own logger class extended from AbstractLogger
