Poll it to follow the connection; it never changes anything. Follow each response's `instructions`. ## OpenAPI ````yaml /openapi.yaml get /integrations/{key}/connect openapi: 3.0.3 info: 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__...`). 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. servers: - url: https://app.finta.com/api/v1 description: Production security: - bearerAuth: [] tags: - name: Company description: Retrieve company metadata - name: Team description: Retrieve company members and manage invitations - name: Categories description: List your chart of accounts categories - name: Rules description: Company automation rule definitions. - name: Departments description: List the departments available to the authenticated company - name: Integrations description: List the authenticated company's integrations and their connection status - name: Aggregations description: >- Compute totals for one category and its descendants, as a single figure or grouped by merchant or month - name: Transactions description: > Transactions are what your bank shows you: a single line like "AWS charged you $499."
