REST API

The API exposes your sheets for reading and writing. Payloads follow the shape of the Airtable API: an integration written for Airtable transposes without relearning anything.

Base URL: https://rowbase.co/api/v1

Authenticate

Create a token from API tokens, in the sidebar — administrators only. You tick the tables it can reach; it sees nothing else. The secret is shown once.

Authorization: Bearer rowb_…

With no header, the response is 401 AUTHENTICATION_REQUIRED. With a revoked or unknown token, 401 INVALID_API_KEY. With a table outside the token's scope, 403 NOT_AUTHORIZED.

Throughput is capped at five calls per second per token.

List the tables

GET /api/v1/tables

Returns the token's tables, their sheets, and each sheet's columns. This is where you read the identifiers used by the other calls.

{
  "tables": [
    {
      "id": "1",
      "slug": "lar",
      "name": "LAR",
      "sheets": [
        {
          "id": "5",
          "slug": "sheet-1",
          "name": "Sheet 1",
          "fields": [
            { "id": "fld20", "name": "ID", "type": "text" },
            { "id": "fld23", "name": "Email", "type": "email" }
          ]
        }
      ]
    }
  ]
}

A table and a sheet can be addressed either by slug or by numeric identifier.

List records

GET /api/v1/tables/{table}/{sheet}/records

{
  "records": [
    {
      "id": "0c8f2b16-1f3e-4a91-9a0c-2b7d0f5c8ab1",
      "createdTime": "2026-07-27T00:06:46.000Z",
      "fields": { "ID": "…", "Website": "lettre-ar.com" }
    }
  ],
  "offset": "100"
}

A record's identifier is a UUID, unrelated to its position or to the internal key. Cells are keyed by column name; an empty cell is absent from the payload.

Parameter	Effect
pageSize	Records per page, 100 at most and by default
offset	Resumes at the next page, returned while more remain
maxRecords	Caps the total returned
fields[]	Returns only these columns, by name or by fld…
sort[0][field], sort[0][direction]	Sorts on a column, asc or desc
returnFieldsByFieldId	Keys cells by fld… rather than by name

filterByFormula and view do not exist: Rowbase has neither formulas nor views.

Read one record

GET /api/v1/tables/{table}/{sheet}/records/{recordId}

Create records

POST /api/v1/tables/{table}/{sheet}/records

A single row:

{ "fields": { "ID": "abc", "Website": "lettre-ar.com" } }

Or up to ten at once:

{ "records": [ { "fields": { "ID": "abc" } }, { "fields": { "ID": "def" } } ] }

The response mirrors the request: an object for the single form, a records array for the batch form.

Values are converted according to the column's type, just like typing in the grid. An unknown column name returns 422 UNKNOWN_FIELD_NAME — nothing is written.

A row created through the API triggers the sheet's Google Sheets syncs, exactly like data entered by hand.

Update records

PATCH /api/v1/tables/{table}/{sheet}/records

{ "records": [ { "id": "0c8f2b16-…", "fields": { "Website": "example.com" } } ] }

PATCH only touches the cells you send. PUT replaces the row: cells you leave out are cleared.

An update through the API rewrites the row in Google Sheets, just like an edit made in the grid.

Delete records

DELETE /api/v1/tables/{table}/{sheet}/records?records[]=0c8f2b16-…

{ "records": [ { "id": "0c8f2b16-…", "deleted": true } ] }

Ten records at most per call.

Errors

Every error has the same shape:

{ "error": { "type": "UNKNOWN_FIELD_NAME", "message": "Unknown field “Nope”." } }

Type	Code	When
AUTHENTICATION_REQUIRED	401	No Authorization header
INVALID_API_KEY	401	Unknown or revoked token
NOT_AUTHORIZED	403	Table outside the token's scope
TABLE_NOT_FOUND, SHEET_NOT_FOUND, ROW_NOT_FOUND	404	Unknown identifier
UNKNOWN_FIELD_NAME	422	Column name not on the sheet
TOO_MANY_RECORDS	422	More than ten records in one call
INVALID_REQUEST_BODY	422	Malformed body
RATE_LIMIT_REACHED	429	More than five calls per second
