Question

Hi There is a note in the <https wiremock org 3 x docs webhooks and callbacks using data from the original request|Webhooks and Callbacks> documentation that says Webhook templates currently do not support system or environment variables What does this actually mean in terms of the Java and JSON DSLs or Handlebars if that s the case

Tom · Answer

It just means that you can t access system or env vars via Handlebars templating in the webhook fields that support it This might actually be obsolete now that webhooks has moved to the core so worth giving it a try

I tried the `systemValue` Handlebars helper with a system property in the method field and after calling `Webhooks applyTemplating ` on the `WebhookDefinition` the method field value becomes ` ERROR Access to my custom property is denied `

Tom · Answer

Did you permit that property to be used in your startup configuration

Balog Tamás · Answer

I was not aware that that was needed Let me look into that part

Balog Tamás · Answer

As I see `Webhooks` is always initialized with <https github com wiremock wiremock blob master src main java org wiremock webhooks Webhooks java L68|TemplateEngine defaultTemplateEngine > thus the `TemplateEngine` it uses is always initialized with null `permittedSystemKeys` and never permits any keys

Ah I thought I d updated it to use injection We can change that in the next release then this will work
