How to add permissions to an existing Lambda function

Question

Hi Guys,

I have created one lambda function from CLI. I want to grant the Amazon SNS service permission to the lambda function. How can I do that?

Hi@akhtar,

You can grant an AWS service or another account permission to use a function. The following add-permission example grants the Amazon SNS service permission to invoke a function named my-function.

$ aws lambda add-permission \
    --function-name my-function \
    --action lambda:InvokeFunction \
    --statement-id sns \
    --principal sns.amazonaws.com
