Trigger a Webhook with a Webhook

[PaulR282]

Is there a way to trigger a Webhook when another Webhook is executed? I want to do 2 requests in a specific sequence. The first one is working great. If I select "Content types: Extras > Webhook", "Events: Job terminations" it won't trigger (I guess because Webhooks are not Jobs in netbox, although it is a job when you look in the django admin ui).

I think you need an external workflow engine for this: Netbox webhook calls workflow engine, workflow engine calls other actions.

If you want a pretty framework then something like Camunda 7 will work, if you can stomach a Java process running in your network; or there are python ones like airflow, prefect and luigi. It's a while since I looked into options for these, but there's a big list here.

Otherwise, you could make your first webhook call the second one just before it's finished.

Thanks for the ideas. How could I make the first one call another one within netbox? (last line)

What I meant was:

Netbox ----> Webhook receiver 1 ----> Webhook receiver 2

That is, you modify Webhook receiver 1 (i.e. the application which receives the webhook call) so that it calls Webhook receiver 2 directly, when it's finished its work.

Another option would be to write a small webhook proxy, which calls the other two hooks in sequence:

Netbox ----> Webhook proxy ----> Webhook receiver 1
                          `----> Webhook receiver 2

But arguably that's a custom-written, mini external workflow engine. (Probably only requires a dozen lines of python though)

Ok, thanks. This would of course be an option but since it's not very dynamic, I'll stick with only calling webhooks with netbox and not calling the second one which is a bit optional.
