Lambda is a seam, not a place to hide a CRM — Ecosystem

Glossary

Contact One interaction: a call, chat, task, or email. A transfer usually creates another contact linked by PreviousContactId and NextContactId.
Connect Customer The name used from 28 Apr 2026 for the contact center product previously called Amazon Connect.
CloudWatch Metrics and flow logs. Alarm at 80 percent of a quota, which is the operations guidance in the email quota note.
Kinesis Data Streams The durable stream for CTRs and agent events when more than one consumer must read them.

Sister technologies

A flow fails in IAM, a Region, a log group, or a network rule long before it fails as a 'Connect bug'.

Config and troubleshooting

Setting the Lambda console timeout to 30 seconds and assuming the flow will wait.

IAM, Lambda, S3, Kinesis, and CloudWatch are not inside the instance. This stack creates the instance and turns on flow logs and Contact Lens.

Integration map

Join records on ContactId. The integration map room lists the seams.

Cross-platform bridges

A CUCM calling search space is not a routing profile, but the profile is the closest idea of 'who can receive what'. A partition is not a Connect object. A UCCX CSQ and a UCCE skill group map to a queue. Precision steps map to routing criteria. A script, an Architect flow, and an Avaya vector map to a contact flow.

Future hooks

Hooks you can adopt later: EventBridge contact events, the CTR stream, agent events, Kinesis Video, Customer Profiles events, Cases, Show view, data tables, External Tool, and the flow language JSON in your pipeline. Live Sync and Agentic CX are the 2026 hooks for guided and agentic experiences.
