Thanks for the reply.

I think my major question is, how can I make multiple asynchronous API calls (for obtaining the Stop info as well as obtaining the ETA for each route). Any example would be a great (pipe requests).

Thanks for the help.

I created a module that would display the estimated time of arrival (ETA) in a particular stop. But that can’t be done using a single API. Here is what I need

• At start time I need to obtain the list of routes by calling an API

• Every single minute for each route I need to collect the ETA for each route (Multiple API calls). And then update the grid accordingly.

I have done the first part but have no idea how to do the second part. Thanks for the help.
