I would like to generate a single webhook so that I am able to dynamically enter different channel names instead of having to create a URL for each one. Is this possible?
In the setup page for the Splunk slack addon you can set a default webhook url. After setting the default you should no longer have to specify a webhook for each alert, only the channel. You should only need one web hook per slack instance/company not per channel.
The configuration URL will be something like this.
Even though you created the webhook with one channel, I believe it should be usable to post to any channel. A far as I know we only have one webhook defined, however, we are able to post to any valid slack channel. In each alert you will still specify #channel
We tried setting up the webhook, but it redirects us to the channel we first set it up for. No matter what we put in #channel it sends us to the configured webhook. Do you mind sharing how you generate yours?
I tested on a free Slack instance and had the same issue of it pinning to one channel. This seems like an an issue on the Slack side. I couldn't figure out how to grant more channels to my generic Slack app I created for the purpose of having an incoming webhook. I will post if I find the answer.
