I have got a requirement to update 6k records in Salesforce from external system in every 4 hours. Can you please suggest what would be best way for this .
1) Should I use the standard Bulk API ? How to handle all batch process that will be created ?
2) Is SOAP a good option too? I know , it's not in much use nowadays.
3) Can I think of REST in HTTP Post as well for this much of data ?
Please advice the best approach.
P.S. I can't use a middleware integration tool.
