Endpoint is not created after serverless deployment

Question

I am trying to deploy a lambda function using serverless framework, the deployment is successful but i am not able to see the api gateway for the lambda function , and no endpoint is created after deployment , i am posting the code below

serverless.yml

# Welcome to Serverless!
#
# This file is the main config file for your service.
# It's very minimal at this point and uses default values.
# You can always add more config options for more control.
# We've included some commented out config examples here.
# Just uncomment any of them to get that config option.
#
# For full config options, check the docs:
#    docs.serverless.com
#
# Happy Coding!

service: learning-serverless-post-apigetway
# app and org for use with dashboard.serverless.com
#app: your-app-name
#org: your-org-name

# You can pin your service to only deploy with a specific Serverless version
# Check out our docs for more details
# frameworkVersion: "=X.X.X"

provider:
 name: aws
  runtime: nodejs12.x

# you can overwrite defaults here
#  stage: dev
#  region: us-east-1

# you can add statements to the Lambda function's IAM Role here

With your functions definition in the serverless.yml you need to tell it explicitly that there needs to be an http event trigger added to it. Serverless lets you set a large number of possible event triggers within the AWS eco system so you need to explicitly define which you want for a particular Lambda function. And the change is as simple as a few more lines than you already have:

functions:
 hello:
  handler: handler.hello
  events:
   - http:
       method: get
       path: /myendpointpath

If you want to see all possible event triggers this page should help:
