Just-in-Time (JIT) Funding<\/b> Advanced APIs now support JIT funding. When a card is swiped at a merchant, the platform sends a real-time webhook to the developer's server. The server then decides\u2014based on proprietary business logic\u2014whether to fund that specific transaction.<\/p>\n<ul data-path-to-node=\"15\">\n<li>\n<p data-path-to-node=\"15,0,0\"><b data-path-to-node=\"15,0,0\" data-index-in-node=\"0\">Example:<\/b> A delivery app only funds a driver's virtual card at the exact moment they are at the restaurant, and only for the exact amount of the customer's order.<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"16\"><b data-path-to-node=\"16\" data-index-in-node=\"0\">II.

Automated Reconciliation<\/b> By embedding metadata (Client ID, Project Code) into the API call when the card is created, every transaction is \"Born Reconciled.\" The data flows through the API into ERP systems like <b data-path-to-node=\"17\" data-index-in-node=\"215\">NetSuite or SAP<\/b> without human intervention.<\/p>\n<h2 data-path-to-node=\"19\">Key Features to Compare: BINs, Fees, and Scalability<\/h2>\n<p data-path-to-node=\"20\">When choosing an industrial-grade issuing API in April 2026, three metrics dictate the success of the program:<\/p>\n<p data-path-to-node=\"21\"><b data-path-to-node=\"21\" data-index-in-node=\"0\">I.
