Alexa video skill, lambda function is not getting triggered - alexa

I have my videos hosted on my server. I have created a video skill to play those videos on fire TV using alexa video skill API. However, my lambda function is not getting triggered when I say "Alexa, play ". Is there anything else that needs to be done? I haven't done any catalog ingestion nor my videos data are on gracenote. Is this a necessary step?

Execute Alexa Skill programmatically

I'm wondering if there's a way to execute an Alexa skill programmatically. Specifically, I want a Raspberry Pi to tell my Alexa device to play a specific song from Amazon Music.
I'm really new to Alexa but the docs I'm reading are all about how to create and manage skills, not call them.
Is this possible?
You should try slightly different product from Amazon. It called Alexa Voice Service
Maybe you are looking to reuse the logic you already have via voice with Alexa to play your songs and use another way via raspberry pi to control the music. This could help you:

dialogflow.com - How to integrate with Google Home / Alexa

I am working on an e-commerce website and would like to integrate with Google Voice assistant or Amazon alexa. I have gone through the dialogflow on how to build a voice assistant. But how It'll be available in amazon alexa or google home that shipped to every household ?
Both Alexa and Google Assistant let you develop things that work very much like websites - Alexa calls them Skills, Google calls them Actions. These are programs that run on your (or a) web server, get HTTPS calls from Amazon or Google with JSON information about what the user has said, and are expected to return JSON information that replies to what has been said.
Amazon requires you to use the Alexa Skills Kit to do the development of these sites, but Dialogflow can export its model to Alexa. Google is a little more open, but since they own Dialogflow, integrating a Dialogflow agent with Actions on Google is very straightforward.
You will need to register your Skill/Action with the appropriate company, but once you have done so, it is available to the users. Alexa users need to "install" the Skill from the Skills directory, although that really just means that they can activate it. The Assistant doesn't require users to activate it this way, but it will be listed in the directory. In both cases, users can then trigger it by saying something like "open Skill Name" or "talk to Action Name".

Alexa appliance discovery in custom skill

I have been checking around on this topic, but have not seen a concrete solution on how to get it working. I am building a Custom Skill for Alexa, which currently supports speech. Now I would like to extend the skill with video streaming to a TV.
The only thing the Custom Skill seems to support for this is streaming to Echo Show with the VideoApp directives?
I have seen answers that say it is possible, just return a list of devices, but these devices and their appliance id's seem to be hardcoded, I would need to get an actual list of devices linked to the users account.
So the question is: is it actually possible to incorporate Video Skill functionality (and device discovery) in a custom skill, or would it need to be a separate skill?
Since the SmartTV is not an Alexa-enabled device, streaming to it will be a separate API from the Alexa APIs.
An Alexa skill is similar to a web API, where the front end, user interface, is Alexa.
Imagine if you were building a website that had a couple of buttons on it and a text box. Users would enter some info in the text box and press one of the buttons to start streaming on the TV. The code behind the website would have to communicate with the smart TV somehow to stream the content.
The same way, your skill code would have to figure out a way to communicate with the Smart TV.
This is not something that Alexa would support directly, so it become necessary to identify the API for your SmartTV and a way to communicate to it from the internet which won’t be trivial.

Alexa Flash Briefing API with SSML

I have created a simple flash briefing skill that reads from a rss feed. However it is pronouncing the name of the company wrong. I have reviewed the SSML page on the amazon developer site, but i do not see a way to get to the js that runs the skill. Is there any way to edit the js behind the skill if I am using the default API? Is there another solution short of writing a standalone skill?
It's not possible to do that yet. SSML is allowed in the Feed content only.
However you can up-vote the idea, you are not the first one who faces this issue.

How to amazon alexa api for a web or mobile app?

I want to use amazon alexa api for my website/ mobile application. I would like to know if it is possible to use and how to integrate alexa, given that I develop my custom skill.
You can use the Alexa Voice Service. You will need to collect the user's audio and then submit it to Amazon. The voice snippet does not need to contain the hotword (e.g. Alexa). You should be able to use most features that don't involve the device and aren't asynchronous. For example, you can utilize the alarm or timer features nor the music streams.
It sounds like you are asking how to allow the user to talk to your website or mobile app.
An Alexa custom skill is something you create to extend Alexa's vocabulary, so to speak. It isn't an alternative to using a mouse or keyboard with an existing app.
A website and a mobile app are, or can be, two different ways for a user to access the functionality you provide. Think of an Alexa skill as a 3rd way to access that functionality. A user could ask the Alexa device (Echo, Dot, iPhone Lexi app, etc) to get or perform the same things that your website does.
So for example, if your website explains how your widgets work, then you could create a widget Alexa skill that would allow Alexa user's to ask about your widgets.
The Alexa Voice Service is something entirely different. It is an API to enable adding Alexa voice to a different piece of hardware. For example, my friend Thaddeus created an Alexa Voice Service app called Lexi that runs on an iPhone. This allows a user to talk to Alexa using their iPhone. However, it doesn't add any new capability to Alexa. It only allows me to do things on my iPhone that I can already do on my Echo.
