aws lambda - Using an API key in Amazon API Gateway

Question

I have created an API Key and added it to my functions. I have then deployed the api and tested it but still get:

"message": "Forbidden"

How do I pass the api key with my JSON request as I have been using "x-api-key": "theKey"?

Answer 1

The x-api-key parameter is passed as a HTTP header parameter (i.e. it is not added to the JSON body). How you pass HTTP headers depend on the HTTP client you use.

For example, if you use curl and assuming that you POST the JSON payload, a request would look something like (where you replace [api-id] with the actual id and [region] with the AWS region of your API):

$ curl -X POST -H "x-api-key: theKey" -H "Content-Type: application/json" -d '{"key":"val"}' https://[api-id].execute-api.[region].amazonaws.com
