I’m looking to build a module that allows for the following behavior: 1. less ideal option: a button in the designer that when clicked runs the ‘update project, accept gateway changes’ flow. 2. more ideal: a file watcher that triggers that same flow upon the creation of a specific file, and then deletes the file 3. most ideal: web API that runs that (if it could somehow live on the gateway that’d be awesome but I imagine that would require a nightmare of message handler complexity). Where in the SDK would I look for hooks into that designer update flow? ---

Hi Leor, Is this for 8.3 or 8.1? 8.3 exposes an endpoint to trigger a `projects` scan and a `config` scan. This can be found by running an 8.3 gateway and navigating to `http://localhost:8088/openapi`. From there you can follow the [API Keys](https://docs.inductiveautomation.com/docs/8.3/platform/security/api-keys) guide. For 8.1, I use [Ignition Flint](https://github.com/keith-gamble/ignition-flint) pretty extensively. This supports editing in VS Code and triggers a project scan when you save if the [Ignition Project Scan module](https://github.com/design-group/ignition-project-scan-endpoint) is enabled. Further, the module exposes an HTTP endpoint that allows you to call the scan if you want to roll your own implementation. Doesn't exactly answer your question but I hope this helps. ---

Oh, I know about how to get the _gateway_ to update – my q is how to update the _designer_ ---

There's no **supported** hook for a module to invoke the pull action in the designer. > > [@Leor\_Fishman](#): > > most ideal: web API that runs that (if it could somehow live on the gateway that’d be awesome but I imagine that would require a nightmare of message handler complexity). Adding a route to the gateway is trivial in a custom module: > [@Module Development Example Question](https://forum.inductiveautomation.com/t/module-development-example-question/107639/3): > > Contributing to the central OpenAPI definition from a module is very easy. Just override/implement mountRouteHandlers in your module's gateway hook. The Route class we provide has an OpenAPI builder attached to it you can use to build up a response. @Override public void mountRouteHandlers(RouteGroup routes) { routes.newRoute("/api/v1/session/:sessionId/pages") .type(RouteGroup.TYPE\_JSON) .method(HttpMethod.GET) .requirePermission(PermissionT… Though, you've had such a good idea that it already exists: > **[GitHub - bw-design-group/ignition-project-scan-endpoint: This module provides a REST endpoint for...](https://github.com/bw-design-group/ignition-project-scan-endpoint)** > > This module provides a REST endpoint for triggering a project scan in Ignition. ---

I missed that entirely, thanks!
