Set up API Gateway

1) Create a REST API Gateway

We will be using AWS API Gateway to create a REST API that will be used to communicate with our Lambda functions.

2) Set up auth routes

Create a /auth resource and then /auth/{proxy+} resources. This will act as a catch-all for all supertokens auth routes. Enable CORS while creating the proxy resource.

3) Attach lambda to the ANY method of the proxy resource

Click on the "ANY" method and then "Integration" to configure the lambda function. Check Lambda proxy integration and then select your lambda function.

4) Enable CORS for the proxy path

Click on the {proxy+} resource and then "Enable CORS" button to open the CORS configuration page.

• In the CORS configuration page do the following:
  • Select the 'Default 4XX' and 'Default 5XX' checkboxes under Gateway responses
  • Select the 'OPTIONS' checkbox under Methods
  • Add rid,fdi-version,anti-csrf,st-auth-mode to the existing Access-Control-Allow-Headers
  • Set Access-Control-Allow-Origin to '<YOUR_WEBSITE_DOMAIN>'
  • Select Access-Control-Allow-Credentials checkbox

4) Deploy the API Gateway

Click the Deploy API button in the top right corner to deploy the API. During deployment, you'll be prompted to create a stage; for this tutorial, name the stage dev. After deployment, you will receive your Invoke URL.

important

Update apiDomain, apiBasePath, and apiGatewayPath in both Lambda configuration and your frontend config if they have changed post API Gateway configuration.
