I have approval process when i submit it to approval.. Approver is receiving the bell notification but after approving/rejecting the record intial submitter is not receiving any bell notifications.. Privously it used to work for me 

I want to retrieve all contacts with paging support. Such that my organizaion has 7000 contacts, I need to read 100 contcats per api call with paging support. How to accomplish this using SSQL through REST API?

I'm using this api:
https://ap5.salesforce.com/services/data/v42.0/query?q=SELECT Id,FirstName,LastName FROM Contact

Same paging support need for all the modules: leads, accounts, notes, events and tasks etc.

Thanks,
Guna.
