JSON API for Yelp
#AWS Lambda and API Gateway I wanted to learn that tech and here is how I use it:
#Step 1: Setup AWS Lambda
- Download and Install Apex:
curl https://raw.githubusercontent.com/apex/apex/master/install.sh | sh
-
Download and Install AWS-CLI
brew install awscli- sorry windows users, just use the browser :-) -
Create IAM user in AWS Console and give permissions to IAM and Lambda ( Apex will need to create a IAM role and be able to execute/deploy to Lambda). Caution: If you give it FUllAcccess Policy to IAM and Lambda make sure, you remove it afterwards to avoid any security problems.
-
Run
aws configuresetup your user with AWS_ACCESS_KEY & AWS_SECRET_KEY. I usedus-east-1 -
Run
apex init -
Make sure you can deploy. Run
apex deploy -
If it is successful, you can run
apex invoke hello -
Now, do
git clonethis repo intofunctions/hellofolder -
cd functions/hello -
npm install -
cd ../.. -
apex deploy
To test it out that it's working do the following:
echo {"business_url" : "http://api.yelp.com/v2/business/","consumer_key" : "CONSUMER_KEY","consumer_secret" : "COSUMER_SECRET","oauth_token" : "OAUTH_TOKEN","oauth_secret" : "OAUTH_SECRET"} | apex invoke hello
you should get JSON response from Yelp API
Step #2 Integrate with AWS API Gateway:
..... Business URL should be in format: http://api.yelp.com/v2/business/BUSINESS_ID Your business id looks something like aurora-construction-and-design-sarasota https://tpbqwidt0h.execute-api.us-east-1.amazonaws.com/prod/get-reviews?business_url=BUSINESS_URL&consumer_key=CONSUMER_KEY&consumer_secret=CONSUMER_SECRET&oauth_token=OAUTH_TOKEN&oauth_secret=OAUTH_SECRET
