Create a table with a typed column schema and optional folder placement.

OAuth scope: api:write.

POST/api/v2/tables

Authorization

X-API-Key<token>

Send a personal or workspace API key in X-API-Key. See key types and access; operations that reject workspace keys say so in their description.

In: header

Request examples use an API key. For OAuth, replace the X-API-Key header with Authorization: Bearer YOUR_ACCESS_TOKEN.
