Payment method catalog changed (V2 broadcast only) Webhook Webhook

Emitted when an administrator creates a payment method or updates its catalog-visible fields (`name`, `status`, `requisite_types`, `is_cross_border`). Broadcast to every ACTIVE V2 merchant of the tenant with a non-empty webhook_url (legacy V1 merchants never receive it — the V1 wrapper has no catalog callbackType). No-op updates emit nothing. The wrapper is a separate catalog form: the deal fields (`amount`, `currency`, `deal_id`) are absent. This is a NOTIFICATION, not a source of data: on receiving it, re-fetch GET /api/v1/p2p/merchant/payment-methods.

List disputes GET GET

Returns all the merchant's disputes with optional status filtering.
