Chaining Processors

Chaining

Chaining is the process of linking multiple processors into a single configuration so they run in a defined sequence for an endpoint. Cloud API Management supports multiple pre-processing and post-processing steps for chained processors.

Types of Chaining

Proxy Processor Chain

This processor implements pre-process or post-process traffic events. You can chain this processor using Cloud API Management processor (Mashery_Proxy_Processor_Chain) or SDK-based processor. Refer to Proxy Processor Chain Configuration Values for more information.

Chain Adapter

This processor implements pre-process or post-process traffic events. You can chain this processor without using Cloud API Management processor (Mashery_Proxy_Processor_Chain). Refer to the Chain Adapter Configuration Values for more information.

For chaining adapters, use the following Cloud API Management-provided connectors:

• OAuth2 JWT Authentication Connector
• OAuth2 Shared Token Connector

These processors cannot be created using Cloud API Management SDK.

note

You cannot change the authentication event using Proxy Processor Chain (Mashery_Proxy_Processor_Chain) or Chain Adapter (com.mashery.proxy.customer.generic.oauth2-jwt-authenticator), but can only chain pre-processing and post-processing.
