Partner API Changelog

September 2026

2026-09-10

Published our versioning and deprecation policy. In short: deprecations are announced in this changelog, deprecated endpoints remain callable for at least three months, and we contact every partner we can see calling an endpoint before it is removed.
Endpoints deprecated more than six months ago are now hidden from the API reference. They remain fully callable — this is a documentation change only, so no integration breaks today. Hidden in this pass:
- GET /api/v1/customers/{customer_id}/jiko-accounts/ — use List Pockets for Customer
- GET /api/v1/jiko-accounts/{account_id}/ — use Get Pocket
- GET /api/v1/customers/{customer_id}/transactions/ — use List Customer Transactions
- GET /api/v1/jiko-accounts/{account_id}/transactions/ — use List Pocket Transactions
- GET /api/v1/jiko-accounts/{account_id}/transactions/{transaction_id}/ — use Get Transaction
- GET /api/v1/customers/{customer_id}/counterparties/ — use List Counterparties
- GET /api/v1/customers/{customer_id}/counterparties/{counterparty_id}/ — use Get Counterparty
- GET /api/v1/jiko-accounts/{account_id}/statements/ — use List Customer Statements

2026-09-02

Subscriptions can now subscribe to crypto transfer events: transfers.crypto.deposit.success, transfers.crypto.withdrawal.success and transfers.crypto.withdrawal.rejected. The payload carries the crypto_transfer_id of the transfer and the jiko_account_id it settled against. These events are also returned by List Events.

2026-09-01

ACH originations can now be created with the CCD Standard Entry Class code, for use when the counterparty is a business rather than a consumer. CCD must be enabled for your account before use; contact your Jiko representative to request it. Requests using it without it being enabled are rejected with a 403. When sec_code is CCD, company_entry_description is required.
Added a required wire_type field to WIRE transaction activities on the transactions endpoints. It distinguishes an ordinary wire (PAYMENT) from the reversal of a wire booked (REVERSAL) and a wire returned by the counterparty bank (RETURN).
Added an optional original_wire_id field to WIRE transaction activities. It holds the ID of the wire that was returned, and is only populated for RETURN wires.

August 2026

2026-08-13

Added a new endpoint to fetch earnings for all of a customer's pockets in a single call. The response contains one entry per pocket plus their exact field-wise aggregate. By default it covers every pocket that is not closed (at most 30 per call); the pocket_id[] filter narrows the request, and is also the way to include a closed pocket explicitly. Like the single-pocket variant, it supports the wtd, mtd, ytd and all-time periods.

July 2026

2026-07-23

Added an optional display_name field to counterparties. It can be set when creating ach, wire, international_wire, and on_us counterparties, or when updating a counterparty's display_name via the update counterparty endpoint, and is returned on all counterparty responses when listing. Use it to assign a custom name that distinguishes counterparties belonging to the same legal entity.

June 2026

2026-06-09

Added new endpoints for fetching wires:
- List Wires for fetching wires, optionally filtered by pocket_id (a single pocket) and/or customer_id (all of a customer's pockets).
- Get Wire for fetching a single wire, optionally scoped to a customer_id.
The list endpoint supports filtering by direction (INCOMING or OUTGOING).

2026-06-03

Added new optional fields pricing_timestamp and appreciation_per_second to the Portfolio response on the Pockets endpoints. These are populated for pockets backed by accounts with the real_time_yield attribute, and allow consumers to interpolate total_value forward between server-side price updates as total_value + appreciation_per_second × (now - pricing_timestamp).

2026-04-22

Added new optional field transfer_type to Internal Reallocation transfers. Supported values are BANK_TRANSFER (default) and SECURITY_TRANSFER.

December 2025

2025-12-23

Subscriptions can now subscribe to incoming wire events: transfers.wire.in.success and transfers.wire.in.rejected. The payload carries the wire_id of the wire and the jiko_account_id it settled against, matching the shape of the existing transfers.wire.out.* events. These events are also returned by List Events. No polling is required to observe an inbound wire.
Added to this changelog on 2026-09-10; the events have been available since the date above.
