Transactional push notifications API

[fern1]

We urgently need to set up transactional push notifications and our architects and devs have been looking into the documentation 
https://experienceleague.adobe.com/docs/campaign-standard/using/communication-channels/transactional...

https://experienceleague.adobe.com/docs/campaign-standard/using/working-with-apis/managing-transacti...

However, once we were testing the API, it appeared that it is impossible to send bulk transactional messages via API, that the calls to the API are done one by one. Is there a solution to it? using sFTP and files seems like a workaround and it seems strange that adobe wouldn't be able to handle sending them in bulk. 
We are using adobe campaign standard.

Thanks in advance

@fern1,

Currently, ACS doesn't provide any bulk messaging capability through API. If you have a use case submit an enhancement request.

Any alternative for transactional messaging (push) in bulk via ACS?

Here are my thoughts, Consider having a file where you can have all the profiles that you want to send push messages. Using an external system that makes API calls will have to read each row from the file and make an API call ACS transactional event endpoint. One thing to consider is looking at your license on the number of engine calls (per hour) that you can make for transactional events.
