# Update rule

> Updates future matching only; never runs history or repairs past transactions. Requires Accounting setup: Manage and API access: Manage; Transactions: Manage is not required. Supplied action fields merge into existing actions. Omitted fields stay unchanged and null removes an action from the rule, not from past transactions. Supplied conditions replace the entire flat AND list; omission preserves it, including legacy account/card_name text predicates. Legacy fields cannot be submitted as new conditions. Exact identity references and inclusive signed amount boundaries retain their Create semantics. The complete resulting definition is validated atomically and must contain at least one condition and action, including the Asset/nonzero-offset restriction. Explicitly supplied category/department IDs require current selectability/assignability, even if they equal the saved value. Omitted actions retain their existing saved associations within the authorized company/system scope, including system departments available through the company department collection, even if no longer selectable/assignable for a new rule. This does not exempt preserved actions from whole-definition validation. Invalid updates leave the rule and queued history unchanged. Rejects empty bodies, only empty actions, unknown fields, and apply_to_existing_transactions. Valid no-ops return 200 without changing the definition or cancelling queued history. A real edit cancels pending API-created historical work. Already-running history returns retryable 503 rule_busy without changes; retry with exponential backoff. Legacy unassociated UI jobs do not gain these cancellation guarantees. Reads and merges serialize against other definition writes. Exact normalized duplicates excluding this rule return 409 rule_already_exists with the accessible existing rule ID in the message; unavailable duplicate IDs return 503 rules_not_ready. Unknown, foreign-company, global, internal/system, owner-specific and mixed-owner rules all return the same 404 resource_missing. Malformed rule_ IDs return 400 invalid_request. Unsupported stored definitions return 503 rules_not_ready. No new migration or public job API is introduced.

  title: Finta API
  version: '1.0'
  description: >
    The Finta API provides programmatic access to your company's financial data,

    including transactions, journal entries, categories, financial reports, and
    the team directory.


    ## Authentication


    Each API key is scoped to a single company. There is no company ID
    parameter.

    The key already knows which company it belongs to. If you have access to
    multiple

    companies, create a separate key for each.


    A key acts as its owner; it does not have a separate permission snapshot.
    The owner

    must currently have **API access: Manage**, plus the permission required by
    the endpoint:


    | Endpoint | Required permission |

    |----------|---------------------|

    | `GET /company` | Company: View |

    | `GET /team` | Team & access: View |

    | `DELETE /team/invitations/{id}` | Team & access: Manage; target-management
    limits apply. No additional Growth/RBAC gate. |

    | `POST /team/invitations/{id}/resend` | Team & access: Manage;
    target-management limits apply. No additional Growth/RBAC gate. |

    | `PATCH /team/invitations/{id}` | Team & access: Manage; RBAC and
    active/trialing Growth required, with grant and target limits. |

    | `POST /team/invitations` | Team & access: Manage; requested grants must
    also be allowed for the person and plan. |

    | `GET /categories`, `GET /departments`, `GET /rules`, `GET /rules/{id}` |
    Accounting setup: View |

    | `DELETE /rules/{id}` | Accounting setup: Manage and Transactions: Manage,
    including absent retries |

    | `GET /integrations` | Integrations: View |

    | `GET /reports/*` | Reports: View |

    | `GET /accounts`, `GET /cards`, `GET /transactions`, `GET
    /transactions/{id}` | Transactions: View |

    | `POST /transactions/bulk/update`, `GET /jobs/{id}` | Transactions: Manage
    |

    | `PATCH /transactions/{id}`, `POST /accounts`, `POST /transaction_uploads`
    | Transactions: Manage |

    | `GET /journal_entries`, `GET /journal_entries/{id}`, `GET
    /aggregations/total`, `GET /aggregations/totals`, `GET /parties/merchants` |
    Reports: View |


    Permission changes apply to the next request. Removing API access
    permanently revokes

    the owner's active keys for that company; restoring access requires creating
    a new key.


    Authenticate by including your API key in the `Authorization` header:


    ```

    Authorization: Bearer finta_...

    ```


    ### Key prefix convention


    Every Finta credential is prefixed so it can be recognized at a glance in
    logs, error messages, and secret scanners. Today there is one credential
    type and its prefix is `finta_`. As additional credential or token types are
    introduced (for example restricted keys or webhook signing secrets), each
    will have its own distinct prefix that stacks on the brand prefix (e.g.
    `finta_<type>_...`). Treat the prefix as load-bearing: do not strip it
    before sending, and do not assume a missing or unknown prefix is still a
    Finta credential.


    ## Rate Limits


    The API enforces two independent limits. Both surface as `429 Too Many
    Requests`, but they are distinct error codes with different retry guidance.


    ### Per-minute burst limit


    Authenticated requests are limited to **6,000 requests per 60 seconds** (100
    per second) per API key. Unauthenticated requests (missing or invalid key)
    are limited to **120 requests per 60 seconds** per IP address.


    The window is **fixed**, not rolling. Each 60-second wall-clock interval is
    its own counter; all requests within that interval share it, and the counter
    resets to 0 in a single step at the next boundary. Available budget jumps
    from `0` back to the full bucket size (`6000` for authenticated API keys,
    `120` for unauthenticated IP buckets) instantaneously at the boundary,
    rather than aging out one slot at a time. Trust `X-RateLimit-Reset` for the
    exact reset timestamp.


    Successful responses and burst-limit rejections include the following
    headers.

    Do not assume they are present on other errors: early authentication,
    authorization,

    and monthly-limit rejections can omit them. This describes existing header
    behavior,

    not a new quota policy.


    | Header | Description |

    |--------|-------------|

    | `X-RateLimit-Limit` | Maximum requests per window (`6000` for
    authenticated requests, `120` for unauthenticated). |

    | `X-RateLimit-Remaining` | Requests remaining in the current window. |

    | `X-RateLimit-Reset` | Unix timestamp when the window resets. |


    On a 429 for this case, an additional header is included:


    | Header | Description |

    |--------|-------------|

    | `Retry-After` | Number of seconds until the next request is safe. |


    The error body is `type: rate_limit_error` / `code: rate_limit_exceeded`.


    **Retry guidance:** This case is retryable. Honor `Retry-After` as the
    minimum wait, then apply exponential backoff with jitter for any retries
    beyond the first (cap at a few minutes; abandon after a small number of
    attempts to avoid retry storms). Do not retry tighter than `Retry-After`.


    ### Monthly per-company limit


    Each company has a monthly cap on total API calls, independent of the
    per-minute burst:


    | Plan | Monthly cap |

    |------|-------------|

    | Formation | 10 |

    | Startup | 300 |

    | Growth | 30,000 |


    Counts reset at **midnight Pacific Time (US & Canada)** on the 1st of each
    month. This is the Finta application's configured time zone; the cap is
    computed in that zone, not in UTC. Consumers in other time zones should
    convert the local-midnight Pacific boundary to their own clock; note that
    the absolute UTC offset shifts by one hour twice a year for daylight saving
    (PST is UTC-8, PDT is UTC-7). Blocked requests are not counted toward the
    limit. The error body is `type: limit_error` / `code:
    monthly_limit_exceeded`, and the `message` field includes the reset date in
    human-readable form.


    **Retry guidance:** This case is **not retryable in the short term.** No
    `Retry-After` header is sent, deliberately, because the only meaningful
    remediation is to upgrade the plan (Settings -> Plans at app.finta.com) or
    wait until the 1st of the next month. Naive retry loops should branch on
    `error.code` and stop retrying when they see `monthly_limit_exceeded`. SDKs
    that auto-retry on 429 should look at `error.code` (or the absence of
    `Retry-After`) before re-issuing.


    A temporary company limit override, set by Finta support for the current
    month, may change

    the allowance and the wording of the monthly-limit message. It applies to
    every user and

    API key in the company. The error code and no-short-term-retry rule remain
    unchanged.


    ## Pagination


    List endpoints use cursor-based pagination. Pass `limit` to control page
    size

    (default 100, max 500). To fetch the next page, pass `starting_after` with
    the

    `next_cursor` value from the previous response. Responses include `object:
    "list"`,

    `url` (the canonical path of the collection, relative to the API host),
    `has_more`

    (whether more results exist), `next_cursor` (an opaque value to pass
    unchanged as `starting_after`),

    and `data` (the page of items).


    ## Amounts


    Every monetary field in the API follows two non-negotiable rules:


    1. **Integer cents.** Monetary values are integers, never floats and never
    formatted strings. `$499.00` is `49900`. `$1,500.00` is `150000`. Divide by
    100 to get dollars. This avoids floating-point precision errors in financial
    calculations.

    2. **`_cents` suffix.** The field name always ends in `_cents` (e.g.
    `amount_cents`, `balance_cents`, `total_cents`, `net_income_cents`,
    `change_in_cash_cents`, `cash_cents`). If a field name does not end in
    `_cents`, it is not a monetary value.


    These rules apply to every monetary field across every endpoint
    (transactions, journal entries, income statement, balance sheet, cash flow).
    There are no exceptions and there is no "summary" or "display" sibling field
    that returns the same amount in dollars or as a string. If you encounter a
    field that appears to hold a monetary value but does not end in `_cents`, or
    whose value is not an integer, treat it as a bug and report it.


    Sign conventions:


    - **Income statement**: revenue/income amounts are positive, expense amounts
    are negative. Summing every section's `total_cents` yields net income
    without sign-flipping.

    - **Balance sheet**: `balance_cents` carries the natural-sign cumulative
    balance for that account at the report date.

    - **Cash flow**: `amount_cents` is positive for cash inflows and negative
    for cash outflows.


    ## Errors


    Errors return a consistent JSON structure:


    ```json

    {
      "error": {
        "type": "invalid_request_error",
        "code": "resource_missing",
        "message": "The requested resource was not found.",
        "doc_url": "https://www.finta.com/docs/api-reference/errors#resource_missing"
      }
    }

    ```


    ### Status codes


    | Status | Meaning |

    |--------|---------|

    | `200 OK` | Request succeeded. |

    | `201 Created` | A new resource was created, such as an invitation, an
    account, or a transaction upload draft. |

    | `400 Bad Request` | Request was malformed or had invalid parameters. |

    | `401 Unauthorized` | The bearer credential is missing, malformed, or
    unrecognized. The fix is to obtain a valid API key. |

    | `403 Forbidden` | The API key is valid, but the caller does not have
    permission to access the resource. The fix is to regain the required company
    or product-area access. See the `Forbidden` response component for the
    specific codes. |

    | `404 Not Found` | The requested resource, or the endpoint itself, does not
    exist. Unknown or renamed paths (for example an old hyphenated report path
    like `/reports/income-statement` instead of `/reports/income_statement`)
    return this same envelope with `type: invalid_request_error` and `code:
    resource_missing`, as JSON, regardless of the `Accept` header. |

    | `422 Unprocessable Entity` | Invitation data failed validation, for
    example an invalid email or a conflicting invitation or existing teammate. |

    | `429 Too Many Requests` | Either the per-minute burst rate limit
    (retryable, with `Retry-After`) or the monthly per-company API call limit
    (not retryable in the short term, no `Retry-After`). Branch on `error.code`
    to distinguish the two and avoid retry storms on monthly exhaustion. See the
    Rate Limits section for the full retry guidance. |

    | `5xx` | An unexpected error on Finta's side. Retry with exponential
    backoff. |


    The `error.type` and `error.code` fields are stable identifiers safe to
    switch on programmatically. The `error.message` is human-readable and may
    change without notice.

                The error category. `authentication_error` (401) means the
                bearer credential was missing, malformed, or unrecognized.
                `permission_error` (403) means the credential was valid but the
                caller is not allowed to access the resource.
                `invalid_request_error` covers invalid parameters, unavailable
                resources, invitation validation failures, and requests that
                conflict with current state (409). `rate_limit_error` is for
                per-minute burst limits (retry shortly). `limit_error` is for
                monthly API call limits per company (upgrade or wait for reset).
                `api_error` denotes an operation failure on the server (500), or
                temporarily unavailable rule definitions (503 rules_not_ready).
                Retry with exponential backoff; persistent 503 errors require
                operator attention.

        returns 401) but "regain access" (reactivate the user, restore company
        access, restore an active subscription, or ask an administrator for the
        required product permission). These codes can be returned, distinguished
        by `error.code`:
          - `user_inactive` - the user that owns the API key has been deactivated.
          - `user_removed_from_company` - the user no longer has access to the company the key was created for.
          - `company_closed` - the company is closed, closing, or deleted.
          - `subscription_required` - the company does not have an active subscription.
          - `staging_access_denied` - the staging environment is restricted to Finta users.

        Too many requests. Two distinct limits can trigger a 429: (1) Per-minute
        burst limit (6,000 requests per 60 seconds per API key) returns
        `rate_limit_error` / `rate_limit_exceeded` with `Retry-After` header.

        limits vary by plan: Formation (10/month), Startup (300/month), Growth
        (30,000/month). Blocked requests do not count toward the limit.
