Syncs raw CSV data into a Sync API table. You must first set up a sync from a base (instructions in this support article). The apiEndpointSyncId in the path parameters can be found in the setup flow when creating a new Sync API table, or from the synced table settings.
The CSV data can contain up to 10k rows, 500 columns, and the HTTP request's size is limited to 2 MB.
There is a rate limit of 20 requests, per 5 minutes, per base for this endpoint.
