Sandbox: subscriptions become DEACTIVATED on the billing date without creating an Order or Invoice (JP/JPY)

Hi — I’m hitting a wall verifying Subscriptions before going to production, and I’d

like to know whether what I’m seeing is an expected Sandbox limitation.

## Setup

Sandbox, Japan seller account, JP / JPY location, Square-Version 2026-08-19.

A SUBSCRIPTION_PLAN with one SUBSCRIPTION_PLAN_VARIATION, MONTHLY cadence,

STATIC pricing of 3000 JPY.

## What happens

Every subscription I create becomes DEACTIVATED on (or within seconds of) its

billing start date. Nothing is billed and nothing is produced:

  • invoice_ids stays empty

  • charged_through_date is never set

  • no Order is created

  • ListSubscriptionEvents returns only START_SUBSCRIPTION followed by

    DEACTIVATE_SUBSCRIPTION, and the `info` field is null, so there is no

    reason given

## What I have already ruled out

  • Card on file, and no card at all — same result either way.

  • STATIC pricing, and RELATIVE pricing with an order_template_id passed in

    the CreateSubscription `phases` array — same result.

  • A brand new plan, customer and card — same result.

  • Three independent Japan Sandbox test accounts, different merchants —

    same result in all three.

  • The location is ACTIVE with CREDIT_CARD_PROCESSING and AUTOMATIC_TRANSFERS.

  • The Invoices API itself works fine in the same Sandbox: I built an Order

    manually, created an Invoice from it and published it successfully

    (status UNPAID, invoice number issued, public URL returned).

  • One-off CreatePayment in the same Sandbox returns COMPLETED with a

    receipt_url, so the card and the location are usable.

  • automatic_payment_source is rejected on CreateSubscription at this API

    version (“The field named ‘automatic_payment_source’ is unrecognized”),

    so I cannot explicitly request invoice-based billing instead of card.

## Questions

1. Is subscription recurring billing simply not exercised in Sandbox? If so,

is that documented somewhere I can point my client to?

2. If it is supposed to run, what am I missing that causes the immediate

DEACTIVATE_SUBSCRIPTION with no reason?

3. Is there any supported way to inspect what a subscription invoice will

contain — line items, applied tax rate, tax amount per rate — before

going to production? This is for Japanese qualified-invoice (適格請求書)

compliance, so I need to confirm the tax breakdown appears on the invoice

before we bill real customers.

Subscription IDs, all Sandbox:

d4baaaa1-f61e-47b9-a2b4-673603559ca3 (third account, card on file)

b716493c-b3cc-4f51-be09-63b30c116b89 (no card)

ef0a134f-574d-444e-b5c0-39d397c0b168 (card on file)

Happy to share full request/response bodies if that helps. Thanks.

This is an expected Sandbox quirk—Square’s recurring billing engine does not auto-process Sandbox subscriptions. Test payment flows manually via the Invoices API to verify Japanese tax breakdowns beforehand!
