Deprecation Warning!

On April 6th, 2020 we dropped support for all non-HTTP header based authentication (excluding some rss, mail-receiver, and ics routes). This means that API requests that have an api_key and api_username in the query params or in the HTTP body of the request will soon stop working. Please see the example cURL request below for how to update your API requests to use the HTTP headers for authentication.

Are you using HTTP Headers for the API key?
