I created an API using AWS API gateway and deployed it following the steps similar to the tutorial for AWS API gateway. I Connected the API with AWS lambda function on the backend. Everything works fine from inside API gateway's test method but when I access the API from Postman, I get the following error "message": "Signature expired: 20160917T171647Z is now earlier than 20160917T200334Z (20160917T200834Z - 5 min.)" Searching on stackoverflow question AWS SDK Error - Signature not yet current says it may be a problem with system timing. As I am using AWS lambda and API gateway, I don't have control of the system time. What should I debug?

Figured out the solution. The error message is misleading. I was not accessing the full url to the API.
I was accessing something like
https://someChars.execute-api.us-west-2.amazonaws.com/prod/
while the full url is
https://someChars.execute-api.us-west-2.amazonaws.com/prod/myUrlName
