Webhooks not working as expected

[RobertSmart]

Hi,

I think I've implement the webhook functionality correctly.

I have a server set up with the documented endpoints listening for post events.

I have created a tmate.conf file with the required fields in as per the documentation (see below, but changed to point at my server)

set-option -g tmate-webhook-url "http://example.com/tmate_events" set-option -g tmate-webhook-userdata "some private data"

I've then started the static version of tmate as below:

./tmate -F -f ./tmate.conf

I get nothing coming through to my webhook. I've tested it using curl and it is working correctly.

Are webhooks currently working? How can I diagnose where the fault is?

Many thanks,

Rob

Hi, I have a similar situation. Nothing comes from tmate. I also checked with curl and everything works fine then. I was stuck on it.

I was able to make it work, putting the configuration inside the file: /etc/tmux.conf

set-option -g tmate-webhook-url "http://example.com/tmate_events"
set-option -g tmate-webhook-userdata "some private data"

And I run from: /etc/rc.local tmate -F

[RobertSmart]

does it work if you add those options into a tmate.conf file and point to it with the -f flag?

I don't use -f flag

And use the /etc/tmux.conf I don't use /etc/tmate.conf

[RobertSmart]

I'm trying to establish if that is why it doesn't work for me. Did you try it with the -f flag?

can I put other tmate config in the tmux file or will that get ignored?

I don't have tmux installed I never tried to use the -f option

can I put other tmate config in the tmux file or will that get ignored? I don't know that

This works for me too:

File /etc/tmate.conf

set-option -g tmate-webhook-url "https://my.server/tmate_events"
set-option -g tmate-webhook-userdata "rpi_001"

File /etc/rc.local

...
tmate -F -f /etc/tmate.conf
...

The webhook response is:

I have also had an issue with no webhooks being sent/received as if the config was ignored.

Turns out that webhooks are sent from the tmate server and not the tmate host, so you need to use a tmate-webhook-url that is available publicly over the internet and not your local network.
