It follows REST conventions and returns data in JSON format, enabling any system that can make HTTP requests to interact with Zoho CRM data.<\/div>\n<div class=\"gt-section\">\n<h2>Key API Capabilities<\/h2>\n<p>The Zoho CRM REST API supports: fetching single records by ID, listing records with filter criteria, creating new records, updating existing records, bulk operations (create or update up to 100 records per request), deleting records, file attachments, running <a href=\"https:\/\/aaxonix.com\/resources\/glossary\/coql\/\" class=\"sp-content-link\">COQL queries<\/a>, and retrieving module metadata (fields, layouts, picklist values). The API covers all standard and custom modules.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Authentication<\/h2>\n<p>All API calls require OAuth 2.0 authentication. You register a <a href=\"https:\/\/aaxonix.com\/resources\/glossary\/connected-app\/\" class=\"sp-content-link\">Connected App<\/a> in the Zoho Developer Console, obtain an access token, and include it in the Authorization header of each request. Access tokens expire after one hour and must be refreshed using the refresh token.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>Industry Example<\/h2>\n<div class=\"gt-example-box\"><strong>Custom Portal:<\/strong> A manufacturing company builds a custom dealer portal that displays real-time order status for their channel partners. The portal calls the Zoho CRM REST API every 5 minutes to fetch Deal records where the Account matches the logged-in dealer&#8217;s company. Deal status, amount, and expected delivery date are displayed to the dealer without giving them direct access to the CRM.<\/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\/connected-app\/\" class=\"sp-content-link gt-related-pill\">Connected App<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/coql\/\" class=\"sp-content-link gt-related-pill\">COQL<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/deluge-invoke-url\/\" class=\"sp-content-link gt-related-pill\">Deluge invoke URL<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/webhook-crm\/\" class=\"sp-content-link gt-related-pill\">Webhook (CRM)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/bulk-api-crm\/\" class=\"sp-content-link gt-related-pill\">Bulk API (CRM)<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/deluge-scripting\/\" class=\"sp-content-link gt-related-pill\">Deluge Scripting<\/a><br \/>\n<a href=\"https:\/\/aaxonix.com\/resources\/glossary\/sandbox-crm\/\" class=\"sp-content-link gt-related-pill\">Sandbox (CRM)<\/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 REST API?<\/h3>\n<p>The Zoho CRM REST API is a set of HTTP endpoints that allow external applications to programmatically interact with Zoho CRM data.
