You may want to upload your own data to Bytespree rather than using an API connector. In this case, create a new database and choose "Basic database" as the database type. Afterward, from the Warehouse database selection screen, choose "Manage tables and views" from the database actions menu for the newly created database. On the resulting page, at the top-right corner, you'll see a button, which opens a CSV upload dialogue. Follow the steps in this dialogue to complete your CSV upload and import.
