    Hello @Salonika Shantham

     

    For Integration, legacy ERP system with Salesfor, a good middleware tool depends on your needs, but popular options include Mulesoft(great for complex integrations with pre-built connectors), Jitterbit (user-friendly with automation, or Dell Boomi(solid for data flows). Pick one based on your data volume, budget, get, and team experties-start with a pilot to test. 

    For API call limits, Salesforce allows up to 200 records per API call for insert or updates using the REST API, and the Bulk API CAN handle batches of up to 10000 records asynchronously. Your org's total API call limit also applies, so monitor usage in Setup > System Overview.
