Zettle by PayPal provides point-of-sale and payment tools for merchants, including product catalog, inventory, purchases, finance data, gift cards, and card-reader integrations. Its developer platform lets integrators connect POS and commerce systems to those merchant services.
Zettle exposes multiple OAuth-protected HTTP APIs for POS integrations: Product Library, Inventory, Finance, Purchase, Image, Gift Card, plus a Reader Connect REST API with unclear documented auth details; no public GraphQL, MCP server, or CLI surfaced.

First create Zettle app credentials in the Developer Portal. Then obtain an access token through the OAuth API: either authorization code with PKCE, authorization code with client_secret, or assertion grant using a merchant-created API key. Send the resulting token as Authorization: Bearer <token> in API requests, as shown in Include access token and tracking identifier in API requests.
