The CARTO 3 Tokens API allows you to create public tokens that grant access to specific tables, tilests, and arbitraty queries using a specific connection in your CARTO 3 account. Learn more about connections here. A public token allows you to create map layers and fetch data from tables, tilesets, or arbitrary SQL queries in public applications.
CARTO Token API v3 uses an access token as the authorization method. Learn more about obtaining and using access tokens in the general Authorization section.
