You can accept crypto payments on your website in five ways: API, payment widget, CMS plugin, payment link or recurring payments. With a developer, the API fits; without one, choose a widget, plugin or link. The company review takes 1–3 business days, and fees are 0.9% → 0.7% depending on monthly volume.
