Crypto payments glossary
Each term below is explained in one sentence first, then with the statuses, fields and events CryptoLike uses for it. The words are the same everywhere: a status on the checkout page is the same string as in the API and in your webhooks, and a fee is always named — platform fee or network fee.
Use the glossary to read the API documentation, to answer a customer's question about a payment, or to agree on wording inside your team. Every term links to the part of the docs where it lives and to a related guide.
