 #### API: On-line
 
 There's an online way of testing the API URL too, thanks to [REQBIN](https://reqbin.com/post-online). This has less setup and it can be saved if you log into the web site. Please note two things:

 1. The URL entere below must include a trailing '/' unlike the URL entered into the watch settings.
 2. The service imposes a limit on the number requests you can submit without a subscription, so click with purpose! NB. Changing browser buys you a few more clicks.

 #### SSL Certificate Chain
 
 With thanks to [@ziceva](https://github.com/ziceva) for solving this problem. The symptoms are:
+
 1. Using an API URL with SSL (HTTPS), the [web-based editor](https://house-of-abbey.github.io/GarminHomeAssistant/web/) running in a browser on the same phone running Garmin Connect works well.
 2. The exact same configuration is set in the Garmin HomeAssistant application.

 **Solution: Make sure you use a _full chain_ certificate in your HTTPS proxy as some watches might be unable to validate the site certificate alone.**

 This is the web editor for the GarminHomeAssistant watch app, it offers enhanced schema checking and validation over the original JSON schema by using the HomeAssistant API to create a schema based on your HomeAssistant configuration.
