What changed since you last asked — for polling instead of webhooks

GET/v1/changes

One call for a cron job: every invoice, deposit, payout, customer and wallet an event touched after your cursor, each reduced to its LATEST state (the same shape its GET returns). Available on every plan, including the ones without webhooks.

First call: send nothing (the whole log, oldest first) or since=<ISO instant>. Every call after that: send back the next_after you were given as after. The cursor is the event sequence — ordered, gap-tolerant, and the same number a webhook envelope carries, so moving to webhooks later reconciles against the same axis.

has_more: true means the page filled before the log ran out: call again immediately with the new next_after rather than waiting for the next tick. The defaults scan 200 events a call, at most 500.

A resource touched five times in the window appears once, with last_event saying which event that was — an invoice created, quoted and paid between two polls comes back as one paid invoice.

Authorization

apiKey
AuthorizationBearer <token>

Authorization: Bearer mp<64 hex> for live, mptest<64 hex> for test.

The token is the prefix plus 64 lowercase hex characters (32 CSPRNG bytes) and nothing else — no separators, no embedded fields — so nothing in it needs quoting, escaping or encoding. Send it in the Authorization header and nowhere else. Never put it in a query string: URLs reach access logs, proxy logs, browser history and Referer headers, and a key that lands in any of those is a leaked key. A key's KIND (checkout, payout or wallet) is a property of the key, not of the string: it is chosen at creation, returned by GET /v1/ping, and decides which routes the key may reach.

The full key is shown exactly once, at creation. No endpoint can return it afterwards. Moving funds additionally requires signing to be enabled globally, for your project, and for that key — so a read-only key is a supported configuration.

Query Parameters

after?integer

The next_after from your previous call. Omit on the first call.

Formatdate-time
limit?integer

Events scanned per call, not resources returned.

Range1 <= value <= 500
Default200
type?array<>

Only these event types. Repeatable.

Every event your project emitted, newest first

GET/v1/events

Ordered by sequence, the same number the webhook envelope carries — so reconciling "did we miss one?" is a comparison against this list. type may be repeated.

Your events as they happen (Server-Sent Events)

GET/v1/events/stream

A text/event-stream for dashboards and point-of-sale screens; webhooks remain the delivery contract for your backend. Frames: ready once with {cursor}; event with {id, type, created, livemode, scope, data} — scope: "account" carries the same data as GET /v1/events, scope: "funding" is a deposit to one of your funding addresses (GET /v1/billing/funding), trimmed to the transfer; billing with {id, kind, amount_cents, note, chain, asset, created} for each billing-ledger line; ping every 25 s. Every event/billing frame has an SSE id: send it back as Last-Event-ID to resume (replay is limited to the last 10 minutes). Streams close after 30 minutes; reconnect. At most 10 open streams per project.
