Unlike the standard REST API which handles up to 100 records per request, the Bulk API processes operations asynchronously in the background and supports hundreds of thousands of records per job.<\/div>\n<div class=\"gt-section\">\n<h2>Bulk Write API<\/h2>\n<p>The Bulk Write API allows you to insert or update large numbers of CRM records by uploading a CSV file. You create a job, upload the file, and Zoho CRM processes it asynchronously. Once complete, you retrieve a job result that reports how many records were inserted, updated, or failed. This is the recommended approach for data migrations and large-scale imports.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Bulk Read API<\/h2>\n<p>The Bulk Read API allows you to export a large number of records from a CRM module into a downloadable file. You specify the module, fields, and optional filter criteria, then poll the job status until the file is ready for download. This avoids the record-count limits of the standard API&#8217;s pagination.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Industry Example<\/h2>\n<div class=\"gt-example-box\"><strong>Data Migration:<\/strong> A company migrating 200,000 contact records from a legacy CRM to Zoho CRM uses the Bulk Write API. The migration script splits the records into batches of 25,000 per CSV file, uploads each file as a separate job, and polls job status every 30 seconds. Each completed job returns a success\/failure report. Failed records are extracted, corrected, and re-submitted. The full migration completes in 4 hours with 99.2% success rate.<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Related Terms<\/h2>\n<div class=\"gt-related-pills\"><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/crm-rest-api\/\" class=\"sp-content-link gt-related-pill\">CRM REST API<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/connected-app\/\" class=\"sp-content-link gt-related-pill\">Connected App<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/import-crm\/\" class=\"sp-content-link gt-related-pill\">Import (CRM)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/export-crm\/\" class=\"sp-content-link gt-related-pill\">Export (CRM)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/coql\/\" class=\"sp-content-link gt-related-pill\">COQL<\/a>\n<\/div>\n<\/div>\n<div class=\"gt-section\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"gt-faq-item\">\n<h3>What is the Zoho CRM Bulk API?<\/h3>\n<p>The Zoho CRM Bulk API handles large-scale data operations that exceed the standard API&#8217;s per-request limits.
