Hi there 
While configuring a new alert with webhook, I noticed there is no option to send an API Key there.
The only option is user and password or some additional parameters under Authorization header.
Would it be possible to add an option to send an API key instead? or perhaps an “additional header field” where we can specify any key/value the webhook expects?
This service is built at the top of AWS APi Gateway and expects a header with the key x-api-key and its value in order to process the request. If not present I’m receiving 403.
Best,
