How can I integrate SAM with Api Gateway ?

What I'm trying to do is use SAM and Api gateway (stage, api key, user plan).
Is is possible for them work together ? How do I reference them to each other ?

```
from troposphere import Template, Ref
from troposphere.awslambda import Environment
from troposphere.serverless import Function, ApiEvent, SimpleTable, Api
from troposphere.apigateway import RestApi, Method
from troposphere.apigateway import Deployment, Stage, ApiStage

t = Template()

t.add_description(
"Simple CRUD webservice. State is stored in a SimpleTable (DynamoDB) "
"resource.")

t.add_transform('AWS::Serverless-2016-10-31')

# Api Gateway
rest_api = t.add_resource(RestApi(
"ExampleApi",
Name="ExampleApi"
))

# Create a deployment
stage_name = 'dev'

deployment = t.add_resource(Deployment(
f"Deployment{stage_name}",
DependsOn="OmmaClaimLambda", # this is not working
RestApiId=Ref(rest_api),
))

stage = t.add_resource(Stage(
f"Stage{stage_name}",
StageName=stage_name,
RestApiId=Ref(rest_api),
DeploymentId=Ref(deployment)
))

api = t.add_resource(
Api(
"api",
StageName="dev",
DefinitionBody="",
)
)

# SAM

t.add_resource(
Function(
"OmmaClaimLambda",
Handler='index.handler',
Runtime='nodejs8.10',
CodeUri='s3://sam-demo-zd/lambda.zip',
Environment=Environment(
Variables={
}
),
Events={
'GenReport': ApiEvent(
'GetResource',
Path='/report',
Method='post',
),
'PostLineNum': ApiEvent(
'GetResource',
Path='/linenum',
Method='post'
),
}
)
)

print(t.to_json())

# Finally, write the template to a file
with open('LambdaMultipleApi.json', 'w') as f:
f.write(t.to_json())

# Finally, write the template to a file
with open('LambdaMultipleApi.yaml', 'w') as f:
f.write(t.to_yaml())

```
