Upsert Account to Salesforce

Nexova syncs B2B customer accounts from an internal database to Salesforce using an upsert operation. You will map a nested JSON payload into a flat Salesforce SObject structure, utilizing explicit type casting and conditional field inclusion to prevent the Salesforce REST connector from throwing invalid payload errors.
