As promised, I am sharing the video of how I have automated WhatsApp notifications from my apps.
Firstly to make it simple I created a simple app to showcase the automation.
For the automated messages I found this tool called Message Auto Sender
It has a predefined API URL which, when called, sends WhatsApp messages automatically from the business number which is used to login on the tool. It automates the browser and not WhatsApp itself and has some guidelines about how to use it. (Not sure if it will work in every country)
The app captures data on the google sheets where a google scripts processes the data and creates a URL to match the required API. I have explained how I have done it in the video.
The script is attached here if somebody needs to copy it.
Test the notifications on this app: https://whatsapp.glideapp.io/

Using the same concepts, I have created many apps which send WhatsApp notifications and reminders on order creation, new entries, status updates, task assignments, reminders for deadlines etc.
My apps:
Service Requests
Task Assignment
Project Management
Grocery Store
In case anybody needs more help from me professionally for any integration, you can submit your requests on the app above and I will get in touch with you.
Also, DM me if you are planning to buy the service, I could arrange a discount.
