Table of Contents


Introduction

ISHRestClient is a JavaScript based class to handle REST calls. It allows to execute any REST call and provide useful utility methods to prepare a JSON REST response.

Glossary

  • ISHRestClient - Intershop REST Client

Configuration

To configure the ISHRestClient utilize the following methods:

  • client.host('/INTERSHOP/rest/WFS');
    • Set the Intershop host part of the REST url in the Intershop REST client.
  • client.prefix('inSPIRED-inTRONICS_Business-Site/-');
    • Set the REST prefix part of the REST URL with the Domain and URLIdentifier in the Intershop REST client.
  • client.token('demo@PLAIN:lcmI551YIjY=|VDcwS0RnQVZJcXNBQUFGV0Y0R3owQWM0QDE0NjkxODA0NTQ2NDU=');
    • Set the authentication token for the REST request in the Intershop REST client.
  • client.auth('Basic xxxxxxxxx=');

    • Set the basic authentication for the REST request in the Intershop REST client.

      The basic authentication is only needed when the authentication token is not available.

  • client.customer('customers/AgroNet/users/fbirdo@test.intershop.de');
    • Set the URL part with the related customer for whom the request is called.
    • Examples for B2C and B2B:
      • B2C: customers/Patricia
      • B2B: customers/AgroNet/users/fbirdo@test.intershop.de

Automatic REST Client Configuration

If there is a RESTConfiguration instance available the ISHRestClient implementation sets the related configuration values automatically.
