--- title: Solana RPC WebSocket Methods description: >- Reference index for Solana RPC WebSocket methods. Use this page to find PubSub subscription methods by category, shared JSON-RPC WebSocket request conventions, and links to detailed method pages. url: /docs/rpc/websocket type: reference related: - /docs/rpc - /docs/rpc/json-structures - /docs/rpc/http --- Open an individual method page for request parameters, examples, notification payloads, and unsubscription behavior. For shared response objects reused across WebSocket methods, see [Solana RPC JSON Structures Reference](/docs/rpc/json-structures). ## Request Format Solana RPC WebSocket methods use [JSON-RPC 2.0](https://www.jsonrpc.org/specification) over a persistent WebSocket connection. Connect to the PubSub endpoint at `ws://
/` or `wss://
/`. | Field | Type | Description | | --------- | -------------------------- | ----------------------------------------------------------------------------------- | | `jsonrpc` | `string` | JSON-RPC version. Set this to `"2.0"`. | | `id` | `string \| number \| null` | Client-supplied request identifier. The server echoes it in the subscribe response. | | `method` | `string` | PubSub method name, such as `accountSubscribe` or `slotSubscribe`. | | `params` | `array` | Ordered method parameters. Use an empty array when the method takes no parameters. | Many subscription methods take the optional [`commitment` parameter](/docs/rpc#configuring-state-commitment). If unspecified, subscriptions that accept commitment default to `finalized`. ## Notification Format After a subscribe request succeeds, the server returns a numeric subscription id in the JSON-RPC response. Later notifications are pushed as JSON-RPC messages with a method-specific notification name and the active subscription id. | Field | Type | Description | | --------------------- | -------- | ------------------------------------------------------------------------------------------------------------ | | `jsonrpc` | `string` | JSON-RPC version. | | `method` | `string` | Notification name, such as `accountNotification` or `slotNotification`. | | `params.result` | `any` | Method-specific notification payload. Many methods include a `context` object and a method-specific `value`. | | `params.subscription` | `number` | Subscription id returned by the corresponding `*Subscribe` method. | For notifications that include `context` and `value`, PubSub includes `context.slot` and omits `context.apiVersion`. ## Method Reference ### Accounts | Method | Description | | -------------------------------------------------------------- | ---------------------------------------------------------------------- | | [`accountSubscribe`](/docs/rpc/websocket/accountsubscribe) | Subscribe to notifications when one account's lamports or data change. | | [`accountUnsubscribe`](/docs/rpc/websocket/accountunsubscribe) | Cancel an `accountSubscribe` subscription. | | [`programSubscribe`](/docs/rpc/websocket/programsubscribe) | Subscribe to notifications for accounts owned by a program. | | [`programUnsubscribe`](/docs/rpc/websocket/programunsubscribe) | Cancel a `programSubscribe` subscription. | ### Transactions | Method | Description | | ------------------------------------------------------------------ | ---------------------------------------------------------------- | | [`logsSubscribe`](/docs/rpc/websocket/logssubscribe) | Subscribe to transaction log messages that match a log filter. | | [`logsUnsubscribe`](/docs/rpc/websocket/logsunsubscribe) | Cancel a `logsSubscribe` subscription. | | [`signatureSubscribe`](/docs/rpc/websocket/signaturesubscribe) | Subscribe to status notifications for one transaction signature. | | [`signatureUnsubscribe`](/docs/rpc/websocket/signatureunsubscribe) | Cancel a `signatureSubscribe` subscription. | ### Blocks | Method | Description | | ---------------------------------------------------------- | ----------------------------------------------------------------------------------- | | [`blockSubscribe`](/docs/rpc/websocket/blocksubscribe) | Subscribe to block notifications as blocks reach confirmed or finalized commitment. | | [`blockUnsubscribe`](/docs/rpc/websocket/blockunsubscribe) | Cancel a `blockSubscribe` subscription. | ### Cluster | Method | Description | | ------------------------------------------------------------------------ | -------------------------------------------------------------------- | | [`rootSubscribe`](/docs/rpc/websocket/rootsubscribe) | Subscribe to notifications when the validator sets a new root slot. | | [`rootUnsubscribe`](/docs/rpc/websocket/rootunsubscribe) | Cancel a `rootSubscribe` subscription. | | [`slotSubscribe`](/docs/rpc/websocket/slotsubscribe) | Subscribe to notifications when the validator processes a new slot. | | [`slotUnsubscribe`](/docs/rpc/websocket/slotunsubscribe) | Cancel a `slotSubscribe` subscription. | | [`slotsUpdatesSubscribe`](/docs/rpc/websocket/slotsupdatessubscribe) | Subscribe to tagged slot lifecycle updates emitted by the validator. | | [`slotsUpdatesUnsubscribe`](/docs/rpc/websocket/slotsupdatesunsubscribe) | Cancel a `slotsUpdatesSubscribe` subscription. | | [`voteSubscribe`](/docs/rpc/websocket/votesubscribe) | Subscribe to gossip vote notifications. | | [`voteUnsubscribe`](/docs/rpc/websocket/voteunsubscribe) | Cancel a `voteSubscribe` subscription. |
