Using AWS Lambda with AWS CodeCommit

You can create a trigger for an AWS CodeCommit repository so that events in the repository will invoke a Lambda function. For example, you can invoke a Lambda function when a branch or tag is created or when a push is made to an existing branch.

Example AWS CodeCommit Message Event

{ "Records": [ { "awsRegion": "us-east-2", "codecommit": { "references": [ { "commit": "5e493c6f3067653f3d04eca608b4901eb227078", "ref": "refs/heads/master" } ] }, "eventId": "31ade2c7-f889-47c5-a937-1cf99e2790e9", "eventName": "ReferenceChanges", "eventPartNumber": 1, "eventSource": "aws:codecommit", "eventSourceARN": "arn:aws:codecommit:us-east-2:123456789012:lambda-pipeline-repo", "eventTime": "2019-03-12T20:58:25.400+0000", "eventTotalParts": 1, "eventTriggerConfigId": "0d17d6a4-efeb-46f3-b3ab-a63741badeb8", "eventTriggerName": "index.handler", "eventVersion": "1.0", "userIdentityARN": "arn:aws:iam::123456789012:user/intern" } ] }
