how to change the source branch of the AWS codepipeline through aws lambda(python)?

Question

Using AWS code pipeline, here in source i configured a branch of a repo(using bitbucket repo) and ill release the pipeline it will build and deploy. I used to change the source branch manually by editing the pipeline. Now i want to do this through aws lambda(python). Facing trouble with "client.update_pipeline". is this is the right way or what should i do? https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/codepipeline.html#CodePipeline.Client.update_pipeline https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_UpdatePipeline.html

I want to change the source branch of the pipeline from same repo(bitbucket) via aws lambda(python)

Yes, you can use boto3 for Python in Lambda to update the source branch of your pipeline:

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/codepipeline.html

response = client.update_pipeline(
    name=your_pipeline,
    stage_variables={
        'BranchName': {
            'variable_value': new_branch
        }
    }
)
