How to get alert notification of my Item sells by subscription to eBay

I am new to programming and API. I want to make a little python bot that parses notifications about item selling. So I found this article: https://developer.ebay.com/DevZone/guides/features-guide/default.html#notifications/notifications.html, which tells me that I can subscribe to eBay notification; however, my application should have the capability to receive SOAP requests. So, do I need to develop smth like a SOAP server to be able to receive alerts which tell me that my item has been sold? Maybe you could give some advice to a newbie how to accomplish this task?
No, you don't need a full SOAP server.
For Platform Notifications, you just need to create a simple listener that can listen to input messages (ItemSold, FixedPriceTransation or EndOfAuction, and AuctionCheckoutComplete notifications. You can choose one of these) in XML/SOAP format from eBay's platform and return a simple "200 OK" response.
A good practice is also to check the Notification Signature.
Also, don't mess up the Notification API and Platform Notifications.

Setting up email series in mailgun

I need to set up series of emails with time delays in mailgun.
I'm not sure this is possible without connecting to a CRM like ActiveCampaign, Mailchimp, etc.
If it's possible, can anyone share how it works?
Thanks in advance.
Mailgun is a transactional email service that gives you the ability to send emails from your own web applications. If you want to create a drip campaign like you mentioned, you’d have to add such logic to your web application either through a cron-like task or similar.
There is Mailjet from the same company that offers email automation (another name for drip emails). While I don’t have hands on experience with Mailjet like I do Mailgun, it should be a WYSIWYG interface like what you’re interested in.
At the end of the day it really comes down to what you’re after. Do you want to add email sending to your own applications where you design every aspect of the sending and scheduling logic, or do you want a tool available and ready to go.

Implement websocket notification in react-admin

I would like to notify a user when a specific record changes via someother process (outside of react-admin) in the backend.
For example, status of an order changes and I would like to notify user interested in that order right away in react-admin.
Does anyone have any experience doing this in react-admin? Is there a built-in way do this? If not, are there any resources I can review to implement it?
Thanks for your help.
I use a similar scheme. Using a custom saga that intercepts
various Redux actions and sends them through WebSocket:

Notification on Feeds URL

I am .net developer.I need some clarification in the feeds notification.
I have some list of RSS feed url (e.g more than 100 URL).
My question is I want to develop a console application to get notification if the new item comes in any of the 100 URLS.
What is exact way to do this. Please guide me.
Can we make use of the pubsubhub protocol for this requirement or any other simple approach is available to do this.
Thanks,
Jayakumar
Yes, PubSubHubbub is a protocol that you could use for this. Now, it's not implemented by all feeds out there, so you'll have to resort to polling. Another option is to use services like Superfeedr which provide a webhook mechanism to notify your application when a feed has been updated.

Is this application possible with the twitter api?

I have to make an application where a "sender" can send a message to a group of people and to a location. So when a member of the group reach this place (using location position with the cell phone), he receives all the messages for this location. I have thought to make the application using the twitter API, but I'm not really sure if that functionality is possible.
I thought using twitter would be nice to manage groups and login... the application is written in c++ in QT, so, any ideas for the service to be used to manage messages?
Thank you!
This sounds more like something you'd want to write independently; there's nothing using Twitter would really gain you here.
ok... Here are some points from me.
First of all the person should have enabled geo tagging for you to get the position of the location.
The person should send a Tweet only then you will know the location of the person.
I wouldn't say its not possible but may not work in all cases. I would look for developing a service where the person can join, activate geo tagging and then you can monitor each person's tweet and then send them this location based message.
