# GET /v2/membershipperiod/list

Abrechnungsperioden einer Mitgliedschaft lesen

Liest Abrechnungsperioden genau einer Mitgliedschaft. Ohne id muss membership direkt als Query oder als filter-Eintrag vorhanden sein; fehlt beides, folgt membership_filter_required. Ein id-Selector liest stattdessen einen Einzelbeleg.  Vor der Rückgabe werden verpasste Zahlungsrückmeldungen abgeglichen. Das kann Perioden/Zahlungsreferenzen, Mitgliedschaftsstatus, Gültigkeit, Nutzungsbestand, Audit und Outbox dauerhaft ändern. Sortierung: period_start absteigend, danach Beleg-ID; total ist die Gesamtzahl vor Pagination.

## Authentifizierung

Eine der folgenden Alternativen genügt (ODER). Innerhalb einer Alternative müssen alle Verfahren gemeinsam erfüllt sein (UND).

1. **bearerAuth** (HTTP bearer) — Existing edoobox v2 access token. Never substitute API key/secret headers. **UND** **accountContext** (header: edid) — Selected login/account context from the JWT, not a database primary key. Required even for a JWT with one account.
2. **sessionCookie** (cookie: _edlogin) — Existing browser login session, with the same permission checks as Bearer authentication. **UND** **accountContext** (header: edid) — Selected login/account context from the JWT, not a database primary key. Required even for a JWT with one account.

## Parameter

| Name | Ort | Pflicht | Beschreibung |
| --- | --- | --- | --- |
| filter | query | nein | JSON-Filter: id wählt einen Einzelbeleg; membership wählt die zugehörige Mitgliedschaft. Mindestens eine dieser Auswahlen ist erforderlich. Andere Eigenschaften und expression werden ignoriert. |
| limit | query | nein | JSON-Objekt mit start (Offset) und reply (Seitengröße, 1–500); alternativ eine Zahl. Standard reply=100. Größere Werte werden begrenzt; negative Offsets auf 0 gesetzt. |
| id | query | nein | Einzelobjekt über id auswählen; alternativ gleichnamiger Eintrag im JSON-filter. |
| membership | query | nein | Pflichtauswahl für die Liste: Mitgliedschaft im aktuellen Konto; alternativ filter mit property=membership. |
| X-Edoobox-If-Revision | header | nein | Optional account mutation revision from a preceding authenticated auth-context snapshot. The dispatcher compares it while holding the account lock; mismatch409 requires a new review. |
