This blog will cover how to send in-app notifications using Cryptolens Messaging API. There are two main use cases for Messaging API: one is for updates tracking, and the other is for sending messages in general. You can even choose to send in-application messages to all customers, or a group of customers.
We will mainly cover the dashboard setup and theory behind Messaging API. For code examples, you can either check out the YouTube video or see the full documentation page.
Here is the YouTube video covering this topic, including Python code examples:
Updates tracking in the dashboard
When on the Message Page in Cryptolens, you can specify the Channel and Content that you want to broadcast. For updates tracking, you might want to add the URL where customers can download the latest update to the Content field.
You can implement different channels to send the notification only to some customers. You could, for example, have customers choose if they want to download stable updates, or if they also want to be notified when an experimental version is released. The way to do that is to specify “Experimental” in the Channel field. That way, only customers who your application knows want to receive experimental releases will receive the message.
When you are ready to publish, click on “Add”. In the “Broadcasted Messages” section, you will now find the recently broadcasted message.
For code examples, please check out the full documentation page. The YouTube video at the top of this blog will also show the Python setup.
Notifications in the dashboard
When it comes to update tracking, the main purpose is to make sure that the customer is using the latest update. However, with notifications, you always want to display the latest message for that channel. This means some changes to the code, but in the dashboard, notifications are posted the same way as updates tracking.
One use case for notifications could be to broadcast news. For example, you might want to tell your customers that you offer a limited summer discount. Then, on the Message Page in Cryptolens, you can write “News” in the Channel field, and your message in the Content field, such as “We now offer summer discounts”.
If you want to send in-app notifications for both updates tracking and other notifications, you can simply set up different channels. Use, for example, “Stable” and “Experimental” for updates tracking, and “News” for notifications.
