Here is a design doc / proposal https://docs.google.com/document/d/1KWh7TNt66zMqn6_yBytZ_n_KEXOhHX0Qmmv2JLssy0s/edit?usp=sharing

Then label_replace seems your best option.

It looks like @haibeey is already somehow planning working on this.

@johncming can you please address the comments? Thanks!

cc @csmarchbanks is this pull request valid? should I rebase it and fix it, given the author is not responding ?

+1, nice feature

Let's fix the headers differently ```go // New returns a new Rocketchat notification handler. func New(c *config.RocketchatConfig, t *template.Template, l log.Logger, httpOpts ...commoncfg.HTTPClientOption) (*Notifier, error) { client, err := commoncfg.NewClientFromConfig(*c.HTTPConfig,...

At this point to you think we could have an "http_client" config file? that would enable all the auth scenarios and avoid passwords in the command line.

We could have https://github.com/prometheus/alertmanager/pull/2764 take `bearer-token-file` instead of` bearer-token` then? However, the OP does not specify which header they want to address, is it authorization?

I am against passing secrets in command line it but I do not want to be "on the way" so I have reached the community for more data/ideas/opinions: https://groups.google.com/g/prometheus-developers/c/-lXLx2nYKlk
