An optimized service mediation framework may use customized tokens for reducing cost and latencies per transaction. In particular, a token service and an integration service may function together to generate customized tokens for use by network components within a transaction pathway. Each network component may access information with the token for a predetermined time period and/or for a predetermined number of service calls for service processing tasks related to mapping, security, governing, bridging, transforming, orchestrating, generating events, managing workloads, routing, validating, managing cache, encrypting, queuing and staging, commodity services, transaction management, and quality of service (QoS)/resiliency, among other things.
