Webhook Jinja2 context with environment variables.

[netgab]

Hi,
I have different NetBox instances for production, consolidation and development (using Docker instances).

Upon changes of NetBox data (e.g. setting the VM status to staged), the Webhook triggers a CI/CD pipeline.

Within the pipeline, I need to query the source NetBox instance for additional data. The Webhook data is not enough. However, I don't know the source NetBox instance of the Webhook (they are all behind the same IP).

Of course I could manually add additional body data in the Webhook. For example {"nb_instance": "development"} for the development instance and {"nb_instance": "production"} for the production instance of NetBox. However this approach is too static for me. Especially If I copy the database from the production to the development instance, the Webhook configuration of the production instance is restored and I need the think of a process, to change the Webhook configuration after a DB restore.

Idea would be, that there is the possibility to include environment variables in the webhook using Jinja2 templates.
In my docker-compose.override.yml (there is one for each NB instance), I can add an env var NETBOX_INSTANCE_ID, with my custom instance string.

Question is: Is this something currently works? Are there other approaches for this?
Any thoughts?
