Integrating one means connecting a product&#8217;s checkout, order system, and accounting to that service \u2014 including handling webhooks, refunds, retries, and reconciliation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why It Matters<\/h2>\n\n\n\n<p>The gateway a business chooses affects fees, supported payment methods and currencies, and how many legitimate payments get declined. Products hard-wired to a single provider also tend to find out how expensive that is when pricing changes or a new market needs a local payment method.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Dotcode Applies It<\/h2>\n\n\n\n<p>We build gateway integrations with idempotent requests, webhook handling, and automated reconciliation, so a duplicate callback or a timeout does not turn into a double charge or a missing order.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Payment gateway integration connects your checkout, order processing, and accounting to payment networks with automated webhooks and reconciliation.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What Is Payment Gateway Integration?
