We shoud handle to send webhook on the onboarding endpoint. It can an organisation to handle complexe onboarding on their own.

Interested by this feature, for example to create an custom action when usernamespace is created

This could be implemented without much effort but I'm wondering what the behaviour should be if a webhook is configured but fails to respond ?
Should the webhook be considered mandatory (or even be a "validating" webhook) ? If so, should it happen before the namespace creation (and whatever is done for onboarding) ? If it's not mandatory then admin will have to manually intervene for onboardings done during the webhook downtime.
I don't think Onyxia can support retrying until webhook is back online.
Any thought on this ?

Also note that the events system currently in place (with output in the API logs) has a onboarding.createNamespace event that is triggered at the time of onboarding.
We could also make the events system call a webhook for each event instead or in addition to the current logs output. That would solve this issue and also let admins react to other events.

Discussions and opinions welcome :)

Thank you for your attention :)

In my case, the webhook is not mandatory webhook. We only need (for now) to create user's bucket with policies when a new user log in. In my opinion, if the webhook is down, it's ok for an admin reload the action manually (an api call for example).

The last proposition is also very good, but we can adapt to your choices.

I just wrote #500 that adds webhook as an output for events.
@titigmr I think that will fit your need

Nice thanks! We need to get the user id when the event createNamespace is trigger, the Onyxia api can send it to the webhook?

It's present in the event so it will be sent to the webhook (the data sent to the webhook are the exact same data that are currently output in thé logs) , see https://github.com/InseeFrLab/onyxia-api/blob/main/onyxia-api/src/main/java/fr/insee/onyxia/api/events/InitNamespaceEvent.java
If you want to test the webhook feature, feel free to use tag events-webhook for API image (it's based on API V3 / onyxia V9 so make sure your instance is up to date first)

Perfect!
