Is there a way to enable dynamic response templating via the Java API and not the UI? I currently have

WireMock wm = WireMock.create()
                .scheme("https")
                .host("...")
                .port(443) //etc

wm.register(post(urlMatching("/a-url"))
                .willReturn(aResponse()
                        .withStatus(200)
                        .withBody(readFile("aFile.html"))
                        .withHeader("Content-Type", "text/html")));

Local response templating (where it must be enabled per stub) is on by default in the latest version. So stubs created with

.withTransformers("response-template")

will have it enabled.

Thanks. I replaced

.withBody(readFile("aFile.html"))

with

.withTransformers(readFile("aFile.html"))

and this is what I got in the UI - there's nothing in the body and dynamic response templating isn't enabled. I am on the wiremock latest version 3.3.1 too. Might it be because I'm on the free plan?

You need to literally use

.withTransformers("response-template")

on your stubs, and if you want the response template in a separate file use

.withBodyFile("path/to/your/file")

Amazing, that worked. Thanks.
