It is additive: every v1 request works unchanged against v2 once the base path is updated, and v1 stays GA while partners migrate. | | v1 | v2 | | ------------ | ------------------------------------- | ------------------------------------- | | Base path | `https://sandbox.api.getarkea.com/v1` | `https://sandbox.api.getarkea.com/v2` | | Availability | GA | Beta | | Endpoints | 6 | 9 | ## New endpoints #### Transactions `GET /accounts/{accountId}/transactions` returns booked and pending transactions, filterable with `from` and `to`, newest first. #### Bulk payments `POST /payments/bulk` submits up to 500 SEPA credit transfers as one batch from a single debtor account. #### Consent retrieval `GET /consents/{consentId}` reads a consent's status, expiry, and the accounts it covers. ## Migrating 1. Point your client at the v2 base path. Existing account, payment, and consent calls need no other change. 2. Replace transaction polling built on balances with `GET /accounts/{accountId}/transactions`. 3. Batch recurring payouts through `POST /payments/bulk` — a batch is one authorization instead of one per transfer, and `status: PART` means some transfers were rejected while others settled. > **Info** > > Sandbox keys work against both versions.
