How can I attach the PUT and DELETE method on an API Gateway resource using AWS_PROXY integration?
The PUT method is getting overridden by the DELETE method in lambda triggers.
Is there a way to have both the methods? 
/subs
OPTIONS
PUT
DELETE

Following example in terraform registry documentation, define multiple aws_api_gateway_method resources for the same aws_api_gateway_resource resource:
resource "aws_api_gateway_rest_api" "api" {
name = "MyAPI"
description = "This is my API"
}
resource "aws_api_gateway_resource" "subs" {
rest_api_id = aws_api_gateway_rest_api.api.id
parent_id = aws_api_gateway_rest_api.api.root_resource_id
path_part = "subs"
}
resource "aws_api_gateway_method" "methods" {
for_each = toset(["OPTIONS", "PUT", "DELETE"])
rest_api_id = aws_api_gateway_rest_api.api.id
resource_id = aws_api_gateway_resource.subs.id
http_method = each.key
authorization = "CUSTOM"
}

The original question was using a Proxy - this does not actually set up a proxy, but individual methods for each one. its a subtle difference, but there are advantages to using a proxy - the lack of need for each path_part to be defined for instance (as the path is included in the event sent to the lambda attached to the proxy)

I undertood how to implement multiple methods. If the original question is only about creating a proxy and and api gateway, it is a duplicate of this stackoverflow.com/a/45105470/14105382, isn't it?
As you are using a proxy method, it sends a ton of information to the lambda. Change the proxy method to "ANY" and then in your lambda, check against the event.HttpMethod - and only process based on the ones you want to allow, returning an error message otherwise.
If you dont want to do this, then you need to stop using a proxy method and instead set up an actual resource + each method. THey can connect to the same lambda or different ones, but you can't use proxy to define just two types - its 1 or all.
