All requests to the CARTO APIs (and therefore all developments using CARTO) must be authenticated. When starting a project or building an application, we recommend choosing one between these three strategies:
- Authentication via API Access Tokens: These types of permanent tokens are simple, easy to generate, restrictive, and not tied to specific users. You can use them directly to authenticate your requests. Read more about API Access Tokens.
- Authentication via Single Page Application: Authenticate each user separately by presenting them a login where they need to introduce their CARTO credentials — or their SSO credentials if configured. Once set up, your app will obtain and use OAuth Access Tokens for each user independently. Read more about Single Page Applications.
