Hi Everyone.
I am new to Integration. How can I call External API using continous Asynchronous Apex. How much data can I send in One go/ call.
My requirement is on sending Bulk data using Continuous Asynchronous Apex callout. Lets say 5000 case line items. I divided these into four chunks, each chunk holds 1500. 
Can I make callout by sending all chunks at a time using Continuos Asynchronous way. If so how, please let me know.

Thanks In advance.
