Lambda Northern Europe (NE) Classic Package (Holiday) Provider
A lambda function that listens to an SNS topic, makes a call to the Nordics' Price and Availability ("Price & Avail") cache API and adds the results to a corresponding (DynamoDB) search bucket.
API Gateway Reverse Proxy
In order to use the caching features of the AWS API Gateway to cache requests made to the Nordics API, we need to create an API Gateway endpoint.
Instead of directly calling the NE API endpoint, we use the following setup:
This meant that we had to create an API Gateway endpoint to serve as the reverse-proxy.
at present this is pointing to the Denmark (sd) endpoint for our MVP,
but when we roll-out to more markets it will be 5 minutes of API Gateway setup
(per NE region) and roughly 20 mins to map the URL query parameters for
other regions.
Required Environment Variables
To run/develop/test this Lambda locally you will need a few Environment Variables.
We recommend you export these using an .env file containing the following keys:
export API_GATEWAY_ENDPOINT=https://tc-jira.atlassian.net/browse/ISEARCH-218
export NE_API_KEY=https://tc-jira.atlassian.net/browse/ISEARCH-218
export NE_API_ENDPOINT=https://tc-jira.atlassian.net/browse/ISEARCH-218
export AWS_REGION=eu-west-1
export AWS_IAM_ROLE=arn:aws:iam::12345678:role/lambdafull
export AWS_ACCESS_KEY_ID=YOURKEY
export AWS_SECRET_ACCESS_KEY=SUPERSECRETset the correct values ... if you get stuck ask!
Sample NE Classic API Request & Response:
List of Trips for a 2 adults & 3 children
When we request a list of trips with the following parameters:
{
adults: 2,
children: 3
}This translates to the following API Path:
/trips?adults=2&children=3Sample response (just one trip):

}List of Hotels
Given a list of trips (from the trips API endpoint) we still need to lookup the Hotel details in order to get the photos, ratings, location, etc.
So, imagine that you searched the /trips API endpoint for 2 adults and 3 children
(see above for result sample) you would then need to extract the HotelID
from the packages results and then make a request to the /hotels endpoint
to get the additional data. in the NE API the hotel has the key: wvHotelPartId
e.g: "wvHotelPartId": 10861
/hotels?hotelIds=10861{
"wvId": 10861,
