Authorizations

Authorization

string

header

required

API key: Authorization: Bearer sk_test_... or sk_live_....

Headers

Invoice-Version

string

Pin a dated API release (Stripe-style). Omit to use the current version. An unknown value returns 400 request.invalid_version. Echoed back on every response.

Example:

"2026-07-10"

Invoice-Account

string

Connect: act on behalf of one of your connected accounts (its acct_…/org_… id). Omit to act as your own organization. Not honored on /v1/api_keys.

Example:

"org_2P9connectedacct"

Idempotency-Key

string

Safely retry any POST. The first response is stored for 24h and replayed byte-for-byte for identical retries (the replay adds an idempotent-replayed: true header). Reusing the key with a different body is 409 idempotency.key_reuse; an in-flight duplicate is 409 idempotency.key_processing. This makes retrying a 502/429 safe — no duplicate stamp.

Example:

"a1b2c3d4-e5f6-4789-8abc-1234567890ab"
