Missing Authentication Token

[puhach]

According to the guidelines I created an HTTP endpoint via API Gateway. The url I use is highlighted next to the text Invoke URL. When opened in the browser it displays the following:

{"message":"Missing Authentication Token"}

When used in the web app (simple index.html from the tutorial), nothing happens.

I have experienced an issue similar to yours in the past. This happened for two reasons however the most common is not including the resource in the URL.

For example:Supposedly the resource with the method you are using is called my resource.
If the api generated using api gateway is: https://www.apiimade/dev. Then the url should be https://www.apiimade/dev/myfolder.

Incase this does not work, then the reason may be:
The API request isn't signed when the API method has AWS Identity and Access Management (IAM) authentication turned on.
