Get Lambda function Code details

[ParthaI]

Dear Team,
Is there any API that could be use in order to retrieve AWS Lambda function codes?
Currently the code attribute of GetFunction API call returns following details.

 "Code": { 
      "ImageUri": "string",
      "Location": "string",
      "RepositoryType": "string",
      "ResolvedImageUri": "string"
   },

We would like to be able to display the actual code written in lambda function.
Could you please suggest us the APIs that return the code data?

Thanks!

Hi @ParthaI,

The Location field is a string describing the s3 bucket in which your code lives in. If you used the lambda console to upload your code / write code directly, you will not have access to the bucket.

Alternatively, you can create an s3 bucket yourself, upload your code there in the form of a zip file , and configure the lambda to load the code from the desired s3 bucket.
Just keep in mind that updating the s3 bucket with newer code will not trigger the lambda to rebuild the artifacts and run the updated code.

Thanks @RanVaknin, for your answer.

Is there any direct Lambda Function API to get Lambda Function code details instead of doing S3 configurations?

The only way I know how to do that is using GetFunction

 "Code": { 
      "ImageUri": "string",
      "Location": "string",
      "RepositoryType": "string",
      "ResolvedImageUri": "string"
   },

Location here will be an ARN to your bucket hosting the lambda code. You can make a request to that s3 bucket only if you are the one that provisioned it.
If you used lambda to provision the s3 bucket for you, you will get a 403 and wont be able to access it.

There is no Lambda API operation that will retrieve the code ran on that lambda. That code lives on S3 and lambda just reads it from there.
