Pass Windows API
A pass window is one dated stretch of access on a kind: pass plan: the Saturday 09:00–12:00 a buyer of a match-day pass actually gets.
A pass window is one dated stretch of access on a kind: pass plan: the Saturday 09:00–12:00 a buyer of a match-day pass actually gets. Most windows are generated from the plan's slots; a creator can also place one by hand. A pass series is a slate of these windows, so their ids are what a series points at.
Windows are their own resource rather than an include on the plan: an integration authoring a series needs the ids without pulling a whole plan per source plan. The writes are the three the dashboard's Manage Access Windows panel offers (place a date, cancel one, nudge its holders) and they run the same actions the panel does.

Filters are validated before they reach the query: an unknown status or a malformed date is a 422 VALIDATION_FAILED naming the field, not an empty page.
The list also opens to
project-subscription-plan:view-any. The list shipped under the plan ability before thepass-window:*family had any surface, and it is what the n8n node and the MCP tool docs named. A token holding onlyproject-subscription-plan:view-anytherefore still satisfies thepass-window:view-anygate. Mint new tokens with the precise ability; the alias exists so old ones keep working.
Requires ability
The token must hold this ability, or the call is refused with 403.
MCP tool
Runs the same action from an agent, behind the same ability.
Authorization
bearerToken A personal access token minted on the dashboard under Settings, then Tokens, sent as Authorization: Bearer sbt_live_…. The token carries the abilities each endpoint lists under Requires ability and is frozen to one team.

Path Parameters
The project, resolved by the route binder.
uuidQuery Parameters
One pass plan of the project only.
uuidOne state only: scheduled, open, closed or canceled. Anything else is refused.
Only windows starting at or after this moment, ISO 8601.
date-timeOnly windows starting at or before this moment, ISO 8601.
date-timeKeep only windows a buyer could still purchase.
The 1-based page to return. A page past the last answers an empty data array with meta.total still filled, so a loop can stop without guessing.
1 <= value1Rows per page, 1 to 100. A higher value clamps to the cap silently. Defaults to 50.
1 <= value <= 10050The column to order by. Defaults to created_at; a column the endpoint does not offer falls back to the default rather than failing.
"created_at"asc or desc. Defaults to desc.
"desc"Value in
- "asc"
- "desc"
Legacy alias of per_page, kept for clients that predate it. per_page wins when both are sent.
1 <= value <= 100Responses
200OKapplication/json
The page, soonest first.
401UnauthorizedAUTHENTICATION_REQUIREDapplication/json
The request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an sbt_test_ token on production).
403ForbiddenTOKEN_MISSING_ABILITYapplication/json
The token is valid but does not carry the ability this endpoint requires; error.context.required_ability names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers FORBIDDEN, TEAM_TIER_REQUIRED or CONNECTOR_TIER_REQUIRED with the same status, and says so in its own description.
404Not foundRESOURCE_NOT_FOUNDapplication/json
An id in the path names nothing the token can see. TENANT_MISMATCH: the project sits outside the token's scope:project: allow-list, or the token carries no team scope. Both answer 404 rather than 403 so that existence outside the token's scope cannot be inferred.
422Validation failedVALIDATION_FAILEDapplication/json
The payload broke a rule, and error.fields maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with error.message saying why and no fields.
On this endpoint: VALIDATION_FAILED: when status is not one of the four states, plan_id is not a UUID, or from or to is not a date.
429Too many requestsRATE_LIMITEDapplication/json
The token has spent its 300 requests a minute or 10,000 an hour; Retry-After says when the next one is accepted.
One window, with sellable and holders resolved for it. A window is resolved within the project: a window id that belongs to another project, another team, or to nothing at all is a 404 RESOURCE_NOT_FOUND, so an id's existence never leaks.
| Field | Type | Notes |
|---|---|---|
starts_at | string | ISO 8601, UTC. Store this. |
ends_at | string | ISO 8601, UTC. |
timezone | string | The IANA zone the plan's schedule was authored in. Render window times in this, never in UTC. |
local_range | string | The same window as a person reads it, already in timezone: what the dashboard, the portal and the bot all print. |
duration_minutes | integer | Derived from the two instants. |
status | string | scheduled, open, closed or canceled. Set by the scheduler as the window's start and end pass; canceled only by an explicit cancel. |
source | string | generated from the plan's slots, or manual when placed by hand. Manual windows survive a schedule rebuild; generated ones are regenerated. |
sellable | boolean | Whether a buyer could purchase this window right now: the plan's sales cutoff, resolved for the whole page in one query rather than per row. |
holders | integer | How many purchases currently hold the window. |
Why both UTC and a local range. A pass schedule is authored in the creator's zone and rendered in it everywhere else in the product. Returning only UTC would leave every consumer converting, and getting it wrong across a daylight-saving boundary.
starts_atis for storing and comparing;local_rangeis for showing.

Places a window by hand on a kind: pass plan. This is how schedule_mode: fixed gets its dates, and how a repeating plan gets the one-off that does not fit its pattern.
curl -X POST https://api.subscriby.net/v1/projects/$PROJECT_ID/plans/$PLAN_ID/pass-windows \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN" \ -H "Idempotency-Key: $(uuidgen)" \ -H "Content-Type: application/json" \ -d '{ "starts_at": "2026-09-20 09:00", "duration_minutes": 180 }'Answers 201 with the new window: status: scheduled, source: manual, holders: 0. The request above and "starts_at": "2026-09-20T09:00:00-04:00" describe the same instant for a plan in America/New_York, and both come back as "2026-09-20T13:00:00+00:00". Raises pass.window_scheduled with source: manual.
A manual window is never touched by regeneration: editing pass.slots on the plan rebuilds the generated windows and leaves this one where you put it. Every pass series with a rule is asked to look at the new date afterwards, so a matching series absorbs it as described on the Plans page.
Each refusal below is a 422 VALIDATION_FAILED naming the field, the same wording the dashboard's panel shows.

uuidHeader Parameters
A key unique to this operation, such as a fresh UUID. The same key replays the original 2xx response for 24 hours (with Idempotent-Replay: true), so a retry after a timeout never repeats the write; the same key with a different body is refused with 409.

The key was already used in the last 24 hours with a different request body.
422Validation failedVALIDATION_FAILEDapplication/json
The payload broke a rule, and error.fields maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with error.message saying why and no fields.
On this endpoint: VALIDATION_FAILED: when the plan is not a time-limited pass: a subscription or a series has no windows of its own. VALIDATION_FAILED: when the start is in the past, judged in the plan's own zone. VALIDATION_FAILED: when the length is under the plan's floor or over its ceiling (5 minutes and 30 days by default). VALIDATION_FAILED: when the plan already has a window starting at that instant. VALIDATION_FAILED: when the plan stops selling a fixed number of minutes before a window **ends** and the window is not longer than that cutoff, so it would never be on sale while it runs.
425Too earlyIDEMPOTENCY_REPLAY_IN_PROGRESSapplication/json
The first request with this key is still running; retry in a few seconds and the original response is replayed.

curl -X POST https://api.subscriby.net/v1/projects/$PROJECT_ID/pass-windows/$WINDOW_ID/cancel \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN" \ -H "Idempotency-Key: $(uuidgen)"By the time the response arrives every holder has been resettled, and meta says how:
| Tally | What happened to those holders |
|---|---|
rebound | Moved to the plan's next window on sale, and told so. Their invite links are re-issued when the new window opens. |
refund_due | The schedule had nothing left to offer, so their pass was ended and they were told to ask the creator for a refund. |
legs_dropped | Season-ticket holders who lost this one date and keep the rest of their series. Their message states what the date was worth of what they paid. |
Subscriby never moves the refunds.
refund_dueandlegs_droppedare statements, not actions. The money stays where it is until the creator refunds it at the gateway. An integration that wants to act on them should subscribe topass.holder_strandedandpass_series.leg_dropped, which carry the amount per holder.
Cancelling is a POST verb and not a DELETE on purpose: it resettles every holder, moving them on or ending their pass, which is far too consequential to read as removing a row. It also cannot be undone: the window keeps its start permanently, so the same instant can never be re-created on that plan.
Raises pass.window_cancelled carrying the tallies, plus one event per holder: pass.holder_moved or pass.holder_stranded for ordinary passes, pass_series.leg_substituted or pass_series.leg_dropped for season-ticket holders. A window that is already cancelled is answered 200 with every tally at zero, so a retry after a lost response changes nothing.

Nudges everyone who bought the window but has not yet joined, re-attaching their invite links. It is the panel's Send Reminder button; the automatic reminders a day and an hour before a window opens still run regardless.

A window that has ended or been cancelled reminds nobody and answers 0 rather than refusing. No event fires: the reminder is a message on the connector, not a state change.
This messages real people. Do not repeat it within the same window, and to nudge one holder rather than a whole window use the subscription remind endpoint.

Notifications API
Every alert Subscriby sends a creator (a sale, a support backlog, a bot or channel that went silent, a billing or security notice, a pass window, an onboarding nudge) also lands in the Notifications Center: the sidebar entry with its unread count and popover, and the page at /notifications.
Payment Methods API
Every project configures one or more payment providers so subscribers can buy plans.
