Xolphin API wrapper for PHP

xolphin-php-api is a library which allows quick integration of the Xolphin REST API in PHP to automated ordering, issuance and installation of SSL Certificates.

About Xolphin

Xolphin is the largest supplier of SSL Certificates and Digital Signatures in the Netherlands. Xolphin has a professional team providing reliable support and rapid issuance of SSL Certificates at an affordable price from industry leading brands such as Sectigo, GeoTrust, GlobalSign, Thawte and Symantec.

Library installation

Library can be installed via Composer

composer require xolphin/xolphin-api-php

And updated via

composer update xolphin/xolphin-api-php

Upgrade guide: from v2.x to v3.x

  • Access pagination attributes from $response->getPagination()->{{method}};
  • Remove all EE (EncryptionEverywhere) blocks from your code, it has finally been removed.
  • Make sure you enforce the right types since we enforce strict-typing now.

Upgrade guide from v1.8.3 to v2.x

Update your xolphin/xolphin-api-php dependency to ^2.0 in your composer.json file.

Renamed classes

All endpoint classes have been renamed to a more generic name <resource>Endpoint. You should update your usages.

Calling Endpoint classes

All endpoint classes are started during startup They can be called using $client->certificates->all() instead of $client->certificate()->all().

Using Helpers instead of strings

In version 2.0.0 we introduced Helper classes. These classes contain constants of all static string variables (enums). Use these constants instead of a string, because we will alter these constants whenever we change the corresponding value in the API.

For instance, when creating a DCV for a domain:

$dcvDomain = new Xolphin\Requests\DCVDomain('someDomain', Xolphin\Helpers\DCVTypes::EMAIL_VALIDATION, '');

Certificate download() method returns string

The method download() on the class CertificatesEndpoint now returns the certificate string instead of the GuzzlestreamInterface.
