For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.
## API Version 2
API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
#### Removed methods
In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
- `ledger_header` - Instead, use the `ledger` method.
#### Modifications to JSON transaction element in V2
In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
- JSON transaction element is named `tx_json`
- Binary transaction element is named `tx_blob`
- JSON transaction metadata element is named `meta`
- Binary transaction metadata element is named `meta_blob`
Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
- `ledger_index` - Ledger index (only set on validated ledgers)
- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
This change affects the following methods:
- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
#### Modification to `Payment` transaction JSON schema
When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
- On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
- On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
- On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
- On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
#### Modifications to account_info response
- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) (https://github.com/XRPLF/rippled/pull/3770)
- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
- (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
- The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
- returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
## API Version 1
This version is supported by all `rippled` versions. At time of writing, it is the default API version, used when no `api_version` is specified. When a new API version is introduced, the command line interface will default to the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
This version is supported by all `rippled` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.
### Idiosyncrasies
The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
#### V1 account_info response
### Inconsistency: server_info - network_id
In [the response to the `account_info` command](https://xrpl.org/account_info.html#response-format), there is `account_data` - which is supposed to be an `AccountRoot` object - and `signer_lists` is returned in this object. However, the docs say that `signer_lists` should be at the root level of the reponse.
The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode). However, use of reporting mode is now discouraged, in favor of using [Clio](https://github.com/XRPLF/clio) instead.
It makes sense for `signer_lists` to be at the root level because signer lists are not part of the AccountRoot object. (First reported in [xrpl-dev-portal#938](https://github.com/XRPLF/xrpl-dev-portal/issues/938).)
## XRP Ledger server version 2.2.0
In `api_version: 2`, the `signer_lists` field [will be moved](#modifications-to-account_info-response-in-v2) to the root level of the account_info response. (https://github.com/XRPLF/rippled/pull/3770)
The following is a non-breaking addition to the API.
#### server_info - network_id
The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode).
- The `feature` method now has a non-admin mode for users. (It was previously only available to admin connections.) The method returns an updated list of amendments, including their names and other information. ([#4781](https://github.com/XRPLF/rippled/pull/4781))

The following additions are non-breaking (because they are purely additive).
- `server_definitions`: A new RPC that generates a `definitions.json`-like output that can be used in XRPL libraries.
- In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used. Typically, the `delivered_amount` (in transaction metadata) should be used. To ease the transition, `DeliverMax` is present regardless of API version, since adding a field is non-breaking.
