API Challenge - please help

I have a problem at work and Im wondering if bubble could help me fix it. And if someone could help me do it (for a fee).

I need to send a list of address to 1000+ devices over and API.

In the backend only I need to run another API call to google maps to calculate and store the etas for each stop. A seperate web portal needs to be able to access this eta information via another API.

The only complexity is there would be API’s calls back to the backend that would reorder the list.

The interface on the mobile devices already exists. This is just backend API stuff.
