External services this tenant calls during content delivery, each at a declared pipeline stage.
How this page works
A transformer plugin is an independently deployed HTTP service — a tone-of-voice rewrite, an enrichment step — that the Substation calls while delivering a page. Register one here and it runs for this tenant without any change to the Substation's own code.
Every plugin implements the same contract: POST {url}/transform (data and context in, transformed data out) and GET {url}/health. Plugins run in stage order, then by order within a stage (ascending).
A plugin at stage Block never runs page-wide: it runs only on the blocks of schematics whose manifest declares it under transformers, with the schematic's config merged over the plugin config registered here.
Test calls the plugin's health endpoint by name — the stored API key stays on the server and never appears in this page.

Optional — register an external service to run at a pipeline stage for this tenant.
