Valid status values are "default"
for normal behavior or "frozen"
. Frozen
outputs are hidden from the caller's balance and unspent output requests, are
not returned in nlocktime emails, and cannot be spent. An account containing
frozen outputs can be deleted, whereas an account with unfrozen outputs can not.
Freezing an output requires two factor authentication. Outputs should only be frozen in response to e.g. a dust attack on the wallet. Once a wallet is deleted, any frozen outputs it contained will be unspendable forever.
Note
Only outputs of value less that two times the dust limit can be frozen.

Contains the data describing a network the caller can connect to.
Contains details of all available networks the API can connect to.
For each network listed, a :ref:`network` element is present containing the networks information.
Describes the users spending limits/desired spending limits. A spending limit of zero means the user has no limit currently set.
Warning
Fiat spending limits are deprecated and support will be removed in a future release.
When calling GA_twofactor_change_limits, the caller should pass whether or
not the limit is in fiat, and the value. For limits in BTC, the value can be given
as any unit from :ref:`convert-amount` (e.g. "satoshi"
, "mbtc"
etc).
is_fiat: | true to indicate a fiat limit is being set. |
---|---|
fiat: | A string containing the limit amount in fiat cents. |
fiat_currency: | The currency of the limit. |
is_fiat: | false to indicate a BTC limit is being set. |
---|---|
<value_key>: | A value key from :ref:`convert-amount` giving the limit. |
The returned value from GA_twofactor_change_limits, and the "limits"
section of :ref:`twofactor_configuration` is identical to the set value for
fiat. For BTC, the limit is passed through GA_convert_amount and so all
units are returned.
Describes the status/desired status of an individual two factor method for a wallet.
Describes the desired status of an individual two factor method for a wallet when passed to GA_change_settings_twofactor. Describes the current status of a two factor method when returned as an element of :ref:`twofactor_configuration` by GA_get_twofactor_config.
{
"confirmed": true,
"data": "<method specific data>",
"enabled": true
}
confirmed: | true to confirm the method or if method is confirmed. Confirmation
is performed by the Green server, which requests a two factor code using the
details in "data" . |
---|---|
enabled: | true to enable the method or if the method is enabled. Handled by
the Green server automatically as with "confirmed" . |
data: | Method-specific data, as described below. |
"data"
values
Method | Value | Example |
---|---|---|
"email" |
Email address | "sample_email@my_domain.com" |
"sms" |
Phone number | +123456789 |
"phone" |
Phone number | +123456789 |
"gauth" |
OTP auth URL | "otpauth://..." |
For "gauth"
(Google authenticator), the OTP auth URL is generated by the
Green server, and changes randomly until the user enables this method. The
user should set "data"
to the data value returned for gauth
by GA_get_twofactor_config when enabling.
Note
When returned from GA_get_twofactor_config, the "data"
values
will be partially masked for user privacy/security.
Phone as an SMS backup
If the caller only has SMS two factor enabled, but is unable to receive the
SMS messages sent by the Green server, they may enable phone two factor on
the same phone number without further authorization. This is done by passing
"is_sms_backup"
as true
, as follows:
{
"confirmed": true,
"data": "<existing sms phone number for the wallet>",
"enabled": true,
"is_sms_backup": true
}
Describes the status of a GA_auth_handler. Returned by GA_auth_handler_get_status.
All status JSON contains a "name"
element with the name of the handler being invoked.
The remaining data returned depends on the current state of the handler, as follows:
"done"
:
{
"status": "done",
"action": "disable_2fa",
"result": {}
}
action: | The action being processed. |
---|---|
result: | The data returned from the call, if any. |
"error"
:
{
"status": "error",
"action": "disable_2fa",
"error": "Incorrect code"
}
action: | The action being processed. |
---|---|
error: | A text description of the error that occurred. |
"call"
:
{
"status": "call",
"action": "disable_2fa"
}
action: | The action being processed. |
---|
"request_code"
:
{
"status": "request_code",
"action": "disable_2fa",
"methods": [ "email", "sms", "phone", "gauth", "telegram" ]
}
action: | The action being processed. |
---|---|
methods: | A list of available two factor methods the user has enabled, or the
single element "data" if the call requires more data to continue. |
"resolve_code"
(two factor):
{
"status": "resolve_code",
"action": "disable_2fa",
"method": "email",
"auth_data": {},
"attempts_remaining": "3"
}
action: | The action being processed. |
---|---|
method: | The two factor method the user should fetch the code to enter from. |
auth_data: | Method-specific ancillary data for resolving the call. |
attempts_remaining: | If present, the number of incorrect attempts that can be made before the call fails. |
"resolve_code"
(hardware wallet/external device):
{
"status": "resolve_code",
"action": "disable_2fa",
"required_data": {
"action": "get_xpubs",
"device": {}
}
}
action: | The action being processed. |
---|---|
required_data: | Contains the data the HWW must provide, see :ref:`hw-resolve-overview`. |
"resolve_code"
(request for additional data):
{
"status": "resolve_code",
"action": "data",
"method": "data",
"auth_data": {}
}
action: | Always "data". |
---|---|
method: | Always "data". |
auth_data: | Method-specific ancillary data for processing the additional data request. |
Controls session and internal Tor instance reconnection behavior.
{
"hint": "connect",
"tor_hint": "connect"
}
hint: | Optional, must be either "connect" or "disconnect" if given. |
---|---|
tor_hint: | Optional, must be either "connect" or "disconnect" if given. |
For both hint types, "disconnect"
will disconnect the underlying network
connection used by the session, while "connect"
will reconnect it. if
a hint is not given, no action will be taken for that connection type.
Each session will automatically attempt to reconnect in the background when
they detect a disconnection, unless "disconnect"
is passed to close the
connection first. The session will be notified using a :ref:`ntf-network` when
the underlying network connection changes state.
For environments such as mobile devices where networking may become unavailable to the callers application, the network must be disconnected and reconnected using GA_reconnect_hint in order for connectivity to be resumed successfully. In particular, when using the built-in Tor implementation to connect, failure to do so may result in Tor failing to connect for the remaining lifetime of the application (this is a Tor limitation).
Amounts to convert are passed with a single key containing the unit value to convert, returning all possible conversion values for that value. See :ref:`amount-data` for the list of unit values available.
For example, to convert satoshi into all available units:
{
"satoshi": 1120
}
If "fiat_currency"
and "fiat_rate"
members are provided, the fiat
conversion will fall back on these values if no fiat rates are available.
Callers can check the "is_current"
member in the result :ref:`amount-data`
to determine if the fall back values were used.
For example, to convert bits into all available units, with a fiat conversion fallback:
{
"bits": "20344.69",
"fiat_currency": "USD",
"fiat_rate": "42161.22"
}
It is possible to call this method in non logged Electrum sessions by providing pricing details. For example:
{
"satoshi": 1000,
"pricing": {
"currency": "USD",
"exchange": "BITFINEX"
}
}
{
"bits": "20344.69",
"btc": "0.02034469",
"fiat": "0.02",
"fiat_currency": "EUR",
"fiat_rate": "1.10000000",
"mbtc": "20.34469",
"satoshi": 2034469,
"sats": "2034469",
"subaccount": 0,
"ubtc": "20344.69"
"is_current": true
}
fiat_currency: | Set to the users fiat currency if available, otherwise an empty string. |
---|---|
fiat_rate: | Set to the users fiat exchange rate if available, otherwise null . |
is_current: | true if the "fiat_currency" and "fiat_rate" members are current. |
Lists the currencies and pricing sources (exchanges) available to the session, returned by GA_get_available_currencies. Note that the available pricing sources and/or currencies available at each source may differ between singlesig multisig sessions.
all: | An array of all currecies available across all pricing sources. |
---|---|
per_exchange: | An array of pricing source keys, with the currencies available for each pricing source as the keys value. |

Passed to GA_validate to check the validity of gdk input data.
To validate addressees, for example prior to calling GA_create_transaction:
{
"addressees": {},
"network": "mainnet"
}
addressees: | Mandatory. An array of :ref:`addressee` elements. |
---|---|
network: | Optional. The name of a network to validate the addressees against. |
Validation includes that the address is correct and supported by the network,
and that the amount given is valid. The given amount in whatever denomination
will be converted into "satoshi"
in the returned addressee. For Liquid, a
valid hex "asset_id"
must be present.
It is also possible to validate an addressee for another network than that of
the current session. To do so, pass a network name in "network"
. Note that
when validating against a different network, any amount in the addressee will
not be validated or converted, as the session does not have pricing data for
other networks than its own.
