How to specify request type to AWS lambda invocation with boto3?

Question

I have a lambda function which accepts GET, POST and DELETE requests. I want to invoke it using the boto3 library for python.

According to the documentation, one can invoke a lambda function with boto3 like so:

response = client.invoke(
    FunctionName='string',
    InvocationType='Event'|'RequestResponse'|'DryRun',
    LogType='None'|'Tail',
    ClientContext='string',
    Payload=b'bytes'|file,
    Qualifier='string'
)

But how do I specify my request type? Should my payload contain a field method that has GET/POST/DELETE in it? Or should I pass it through the ClientContext object/string?

Answer 1

Well, when you invoke the lambda function, it doesn't have option for defining the request type.

Workaround is - you can pass that in your payload and access that in your lambda function.

Otherwise ideal approach is to invoke the function with HTTP request as already suggested.
