I have the same situation under the below link.
My expect process from mattermost:
- grafana send alert to mattermost through incoming webhook
- mattermost receive alert from incoming webhook
- mattermost send some message to callback url (my automated testing server) configured from outgoing webhook.
- call url (my automated testing server) received some message from mattermost. and do something based on some message.
I tested the above steps. and then I finally figure out that step 3 never happens.
Incoming & outgoing webhook runs perfectly. but incoming webhook might not be connected with outgoing webhook.
Can the latest mattermost support the outgoing webhook from incoming webhook?
