AWS API-Gateway API-key query

Function for allowing to pass API-Gateway generated api-keys as queryparameter. Allows for some edge-case usage.

This allows for the following usage with AWS API-key managing:

https://some-url/prod/transaction?apikey=some-api-key

Lambda setup

# Install dependency in lambda function
npm i @adneovrebo/api-gateway-apikey-query-authorizer

// In your authorizer lambda function add the following
import apiKeyQueryAuthorizer from '@adneovrebo/api-gateway-apikey-query-authorizer';

exports.handler = apiKeyQueryAuthorizer;

# ZIP content and deploy lambda function with aws-cli (or any other way you like)
zip -r authorizer.zip . && aws lambda update-function-code --function-name <FunctionName> --zip-file fileb://authorizer.zip

Configure API-gateway

1. Create authorizer with the deployed lambda function

2. Go to settings and select API Key Source to be AUTHORIZER

3. On the selected request select the authorizer and set API Key Required to true

4. Deploy API for changes to take effect.

5. Create usage plans and API keys to the desired API.

Happy coding 🎉
