 I am a huge supporter of self-hosted applications; this app is built entirely around Mealie, which itself is a self-hosted app. It's hard to consider data that you have "somewhere else" truly yours.
 
-That said, one of the major roadblocks with integrations comes down to the exposed APIs and authentication schemes. The goal of this app at its inception was to integrate Mealie with [Todoist](https://todoist.com/) and [Amazon's Alexa](https://alexa.amazon.com/) (and, at this time, those are the only supported apps).

-The only way to use the [Alexa List Management API](https://developer.amazon.com/en-US/docs/alexa/list-skills/list-management-api-reference.html) is to request an access token from an authorized Alexa skill. To connect to an Alexa skill you need to [build an Alexa skill and connect using OAuth](https://developer.amazon.com/en-US/docs/alexa/custom-skills/access-the-alexa-shopping-and-to-do-lists.html#alexa-lists-access), which requires a central authentication server that connects to an Alexa skill. If you wanted to do this yourself, you would need to [build your own Alexa skill](https://github.com/michael-genson/Unified-Shopping-List-Helper).

Sadly, [Amazon is removing all support for integrating with Alexa lists](https://developer.amazon.com/en-US/docs/alexa/custom-skills/access-the-alexa-shopping-and-to-do-lists.html). However, while this was still supported, any and all Alexa integrations require an Alexa skill, which connects via OAuth, which requires a central authentication server.

 While Todoist has a [REST API](https://developer.todoist.com/rest/v2/#overview), their webhook subscriptions (which this app uses to initiate a sync) [require an app using OAuth](https://developer.todoist.com/sync/v9/#webhooks), which (you guessed it) requires a central authentication server. You *can* get it working without one, but it's not particularly easy if you're not experienced with OAuth.
