Chaining Processors or Connectors

API Management can support multiple pre-processing and post-processing processors and connectors per endpoint. This is done by linking multiple processors and/or Connectors into one configuration. The entire process is called Chaining.

Chaining Processors or Connectors

note

You can chain only pre-processing and post-processing events. The authentication event cannot be chained.

The following table describes chaining between different events.

Types of Chaining

  • Chaining Processor Using Mashery_Proxy_Processor_Chain

    The processor implements pre-process or post-process traffic events. These processors can either be provided by Boomi or incorporated with the SDK.

    To chain the processors, use Mashery_Proxy_Processor_Chain.

  • Chaining of Processor Using Chain Adapter

    These processors can implement pre-process or post-process traffic events and can be chained without using Mashery_Proxy_Processor_Chain and are provided by Boomi.

    The following are processors acting as chain adapter provided by Boomi.

    • OAuth2JWT Authentication Connector
    • OAuth2 Shared Token Connector

The following table provides information on various chaining combinations.
