subscriptions

Schedule retries for a chosen time

Book a retry on each of a set of past-due subscriptions for a time the operator chose, for the Subscription Billing day drawer.

The time is the operator’s and only the operator’s. Nothing in this platform scores when a charge is most likely to clear, so this endpoint neither picks the hour nor moves it: it writes the instant the caller sent. What it buys an operator is control over when a day’s failed renewals are charged again — out of a payday window, off an hour that already declined — not a prediction.

The retry processor drains bookings on its ordinary five-minute tick, so nothing is charged when this returns. retry_at must be at least 5 minutes ahead, and within 23 hours: past that the processor stops recognising the booking’s provenance and would fall back to its automatic rules, which is a retry the operator did not ask for.

Booking does not reset the subscription’s decline count. An immediate retry does, because it is one hands-on attempt on one renewal; a booking is a batch gesture that can be repeated every morning, and resetting there would hold a subscription in dunning forever instead of letting it reach exhaustion.

Every token is answered. A token is scheduled when a retry is now booked for it, skipped when the subscription is known but cannot take one — with the reason — or failed when no subscription of that token belongs to the caller. A skip is not an error: a renewal that is not past due, will not be due by the chosen time, or sits on a payment method the processor told us to stop charging is reported as passed over.

Booking the same subscriptions for the same instant twice books one retry. Booking them for a different instant moves the existing booking, which is how a mistyped hour is corrected.

Authorizations

Authorization

string

header

required

Bearer token authentication

Body

application/json

The subscription tokens to book, and the time to book them for.

tokens

string[]

required

Subscription tokens. The maximum counts the array as submitted, so maxItems and the server's own refusal agree; duplicates are collapsed after that bound is applied and each subscription is answered once.

Required array length: 1 - 500 elements

Example:

["sb_primex_past_due_002"]

retry_at

string<date-time>

required

When to retry, as an RFC3339 timestamp carrying its offset. The offset is the caller's to state rather than the server's to guess: a bare local hour from a drawer open in one timezone is a different instant on a server running in another.

The time is the operator's choice and nothing else. No model here scores when a charge is likeliest to clear, so the platform neither picks this hour nor adjusts it.

At least 5 minutes ahead — anything nearer is an immediate retry, which has its own endpoint — and no more than 23 hours ahead, the span the retry processor still recognises an operator's booking over.

Example:

"2026-09-15T18:00:00Z"

Response

Every token answered as scheduled, skipped, or failed

One entry per token sent, across three lists.

retry_at

string<date-time>

required

The instant the batch was booked for, in UTC. Echoed so a client states the booked hour from the server's answer rather than from the value it happened to send.

scheduled_tokens

string[]

required

Subscriptions a retry is now booked for.

skipped_tokens

object[]

required

Subscriptions passed over, each carrying why.

Show child attributes

failed_tokens

object[]

required

Tokens that resolved to no subscription of the caller's, and subscriptions whose booking write was refused.

Show child attributes

object | null

required
