“We need an API” is one of the most common sentences in an operator’s first planning meeting, and one of the least useful. An online casino runs on several APIs at once, each from a different kind of supplier, and choosing the right one starts with knowing which job it does.<\/p>\n

This guide maps the main API types, when you need each one and what to ask before you sign. For a deep dive into game APIs specifically, see how casino game APIs work and what to look for<\/a>.<\/p>\n

When You Need Each One<\/h2>\n

Game API or aggregator<\/h3>\n

If you want a handful of studios and have developers to maintain each connection, direct game APIs give you a closer relationship with each studio. For a broad lobby built quickly, an aggregator replaces dozens of integrations with one. Most operators use an aggregator for the bulk of their content and add direct integrations only for their most important studios.<\/p>\n

Sportsbook API<\/h3>\n

You need one if you offer sports betting. The choice is mainly about coverage and licensing: which sports and markets your players bet on, and whether the provider is approved in your markets. Our guide to sportsbook providers<\/a> compares the options.<\/p>\n

Payment API<\/h3>\n

Every operator needs at least one, and usually several, because players in different countries pay differently. Look at local methods, settlement speed and how chargebacks and refunds are handled. Our list of payment gateways for iGaming<\/a> covers the main providers.<\/p>\n

KYC and AML API<\/h3>\n

Licensed markets require you to verify players before they can withdraw, and often before they can play. A verification API automates document and database checks so your team only reviews the exceptions.<\/p>\n

CRM API<\/h3>\n

A CRM needs a steady feed of player events from your platform. The quality of that feed decides how fast your campaigns react. See what iGaming CRM is<\/a> for how the data flows.<\/p>\n

Platform API<\/h3>\n

If you run on a white label or turnkey platform, most of the APIs above are already connected for you, and the platform API is how you extend it. Build your own platform and you own every integration.<\/p>\n
