Hi All,

Am brand new to Salesforce and trying to send list of records in bathces(say 3000 records per batch). And my requirement is to send first 3000 records as a json string to third party API and get a response. If the response is success, then i need to send next 3000 records as json string again. Can anyone help me in sending the data as batches. If i get a response other success, i should not send the remaining data to API.

Thanks in advance.
