Hello, I am running into an issue when getting the gateway context while developing a module to write to tags. The SDK example for writing to tags (located at [Read and Write Tags | Ignition SDK Programmer's Guide](https://www.sdk-docs.inductiveautomation.com/docs/appendix/tag-examples/read-and-write-tags)) begins with the following code: ```auto private void writeReadTagValue() throws Exception { IgnitionGateway context = IgnitionGateway.get(); GatewayTagManager tagManager = context.getTagManager(); TagProvider provider = tagManager.getTagProvider("default"); ``` I have been unable to find the proper library for the IgnitionGateway class. Could you point me to the library I need to include? Thanks in advance! ---

Modules are given the `GatewayContext` in their `setup` methods. You should store it and/or pass it around. `IgnitionGateway` is a private class. ---

Hmmm. Don't know why those example use `IgnitionGateway.get()`. Modules are handed a module context during setup, and are expected to save it for anything like this. (Module context is a thin wrapper around a gateway context.) { Sigh. Sniped. } ---

Got it, thanks for the replies. The tag writing function is in a separate class from the GatewayHook, but still in the gateway scope. Since the context is set in the GatewayHook class, is there a recommended way to pass it over to the class with the tag writing function? ---

> [@BenS](#): > > is there a recommended way to pass it over to the class with the tag writing function? You can make the GatewayContext available as a static/global variable in your hook, or you can pass it via constructor, or you can do whatever other thing you want. It's just a programming decision, not an Ignition SDK decision. Pretend you needed to make the choice in a scenario that didn't involve Ignition at all. ---

> [@Kevin.Herron](#): > > The SDK doc refresh is being spearheaded by people with good intentions but the only involvement the dev team has is consultative / in review I was being a little unfair here. All the docs start with this comment: ```auto // This code example is Gateway scoped and assumes the `GatewayContext` object is available. ``` though it could be more clear that `IgnitionGateway.get()` is not how you actually get the context object, by passing `GatewayContext` as a param to the example function and truly leaving it as an exercise to the reader. ---

Is `IgnitionGateway` the name of the GatewayHook in the example? ---

No, it is the name of the IA non-documented class that **implements** the gateway context interface for the whole gateway. You should not use it in any module code. Use the gateway context instance that your gateway hook is handed during startup.
