Numerous services can accept query string parameters in the URL when a POST request is made with Content-Type: application/x-www-form-urlencoded and other parameters in the body, but it seems AWS API Gateway cannot while also accepting query string parameters.
When I call the AWS API Gateway with a POST Mapping Template for application/x-www-form-urlencoded and query string URL parameters (with a Lambda function), I get the following error:
{
"message":"When Content-Type:application/x-www-form-urlencoded,
URL cannot include query-string parameters (after '?'):
'/prod/webhook?inputType=wootric&outputType=glip&url=...'"
}
Here is an example cURL:
curl -XPOST 'https://{myid}.execute-api.{myregion}.amazonaws.com/prod/webhook? \
inputType=wootric&outputType=glip&url=https://hooks.glip.com/webhook/ \
11112222-3333-4444-5555-666677778888' \
-d "@docs/handlers/wootric/event-example_response-created.txt" \
-H 'Content-Type: application/x-www-form-urlencoded' -v
The specific goal is to get a Wootric webhook event posted to a Lambda function using a URL with query string parameters.

The error message seems pretty definitive but I wanted to ask:
If there's no solution to this, is there a good lightweight solution other than deploying a hosted server solution like Heroku. Also, do other cloud services support this with their API gateway + cloud functions, like Google?
Some examples showing support for both:
Yes,there is a workaround and the key issue is to set the mapping template that will convert string into json . Very detailed example shown in API Gateway any content type.
Please set the request property as "Content-Type", "application/json" for your HttpURLConnection like below connection.setRequestProperty("Content-Type", "application/json");
I had a similar problem, with a 3rd party provider using web hooks. It turns out that my provider is transforming the url path from UPPERCASE to LOWERCASE. Example the endpoint should be apigateway.com/dev/0bscur3dpathRANDOM instead apigateway.com/dev/0bscur3dpathRANDOM. You get the point.
