--- title: "POST /EXPERIMENTAL_changes" method: POST path: "/EXPERIMENTAL_changes" --- # POST /EXPERIMENTAL_changes `POST /EXPERIMENTAL_changes` [Deprecated] Returns changes for a given account, contract or contract code for given block height or hash. Consider using changes instead. ## Request body - JsonRpcRequestForEXPERIMENTALChanges - `id` string — JSON-RPC request id. Auto-populated; can be any string. - `jsonrpc` '2.0' — JSON-RPC protocol version. Always `2.0`. - `method` 'EXPERIMENTAL_changes', required - `params` union, required — It is a [serializable view] of [`StateChangesRequest`]. [serializable view]: ./index.html [`StateChangesRequest`]: ../types/struct.StateChangesRequest.html - object - `block_id` union, required - integer - string - `account_ids` AccountId[], required - `changes_type` 'account_changes', required - object - `block_id` union, required - integer - string - `changes_type` 'single_access_key_changes', required - `keys` AccountWithPublicKey[], required - `account_id` string, required — NEAR Account Identifier. This is a unique, syntactically valid, human-readable account identifier on the NEAR network. [See the crate-level docs for information about validation.](index.html#account-id-rules) Also see [Error kind precedence](AccountId#error-kind-precedence). ## Examples ``` use near_account_id::AccountId; let alice: AccountId = "alice.near".parse().unwrap(); assert!("ƒelicia.near".parse::().is_err()); // (ƒ is not f) ``` - `public_key` string, required - object - `block_id` union, required - integer - string - `account_ids` AccountId[], required - `changes_type` 'all_access_key_changes', required - object - `block_id` union, required - integer - string - `account_ids` AccountId[], required - `changes_type` 'contract_code_changes', required - object - `block_id` union, required - integer - string - `account_ids` AccountId[], required - `changes_type` 'data_changes', required - `key_prefix_base64` string, bytes, required — This type is used to mark keys (arrays of bytes) that are queried from store. NOTE: Currently, this type is only used in the view_client and RPC to be able to transparently pretty-serialize the bytes arrays as base64-encoded strings (see `serialize.rs`). - object - `finality` 'optimistic' | 'near-final' | 'final', required — Different types of finality. - `account_ids` AccountId[], required - `changes_type` 'account_changes', required - object - `finality` 'optimistic' | 'near-final' | 'final', required — Different types of finality. - `changes_type` 'single_access_key_changes', required - `keys` AccountWithPublicKey[], required - `account_id` string, required — NEAR Account Identifier.
