The PyBitmessage API uses XML-RPC.
Enable the API
To enable the API, copy and paste these lines into the bitmessagesettings section of the keys.dat file. Note that the values "username" and "password" below are merely examples, and should be replaced by values that cannot feasibly be guessed:
apienabled = true apiport = 8442 apiinterface = 127.0.0.1 apiusername = username apipassword = password
Additionally, you may optionally include an additional entry which will specify a program which Bitmessage will run when certain events occur.
apinotifypath = c:\\example\\example.exe
One of these arguments will be passed to your program: startingUp, newMessage, newBroadcast. Be sure your program doesn't crash when given newer arguments introduced in the future as this list will likely expand.
To access the Bitmessage API from a remote location, change the apiinterface value from 127.0.0.1 to 0.0.0.0.
The following Python code offers a demonstration of how to create a client that can connect to the PyBitmessage API.
In this example, the username is "username", the password is "password", the IP address of the server running PyBitmessage is 220.127.116.11 (a random example), and the port number which PyBitmessage has been configured to listen on is 8442. In order to connect with the remote copy of PyBitmessage, these settings must match those in PyBitmessage's "keys.dat" file.
import xmlrpclib import json import time api = xmlrpclib.ServerProxy("http://username:email@example.com:8442/") print api.add(2,3)
A more complete example can be found in the api_client.py file in the PyBitmessage source code.
List of Operations
Required arguments are denoted inside < and > Optional arguments are inside [ and ].
|helloWorld||<firstWord> <secondWord>||0.2.7||returns 'firstWord-secondWord'. Used as a simple test of the API.|
|add||<integer> <integer>||0.2.7||returns the sum of the integers. Used as a simple test of the API.|
|statusBar||<message>||0.2.7||Displays the message in the status bar on the GUI|
|listAddresses2||0.4.0||Lists all addresses shown on the Your Identities tab. Returns a list of objects with these properties:
This is called listAddresses2 because 'listAddresses' is obsolete.
|createRandomAddress||<label> [eighteenByteRipe] [totalDifficulty] [smallMessageDifficulty]||0.2.7||Creates one address using the random number generator. label should be base64 encoded. eighteenByteRipe is a boolean telling Bitmessage whether to generate an address with an 18 byte RIPE hash(as opposed to a 19 byte hash). This is the same setting as the "Do extra work to make the address 1 or 2 characters shorter" in the user interface. Using False is recommended if you are running some sort of website and will be generating a lot of addresses. Note that even if you don't ask for it, there is still a 1 in 256 chance that you will get an address with an 18 byte RIPE hash so if you actually need an address with a 19 byte RIPE hash for some reason, you will need to check for it. eighteenByteRipe defaults to False. totalDifficulty and smallMessageDifficulty default to 1.
Returns the address.
Warning: At present, Bitmessage gets confused if you use both the API and the UI to make an address at the same time.
|createDeterministicAddresses||<passphrase> [numberOfAddresses] [addressVersionNumber] [streamNumber] [eighteenByteRipe] [totalDifficulty] [smallMessageDifficulty]||0.3.4||Similar to createRandomAddress except that you may generate many addresses in one go. passphrase should be base64 encoded. numberOfAddresses defaults to 1. addressVersionNumber and streamNumber may be set to 0 which will tell Bitmessage to use the most up-to-date addressVersionNumber and the most available streamNumber. Using zero for each of these fields is recommended. eighteenByteRipe defaults to False. totalDifficulty and smallMessageDifficulty default to 1.
Returns a list of new addresses. This list will be empty if the addresses already existed.
Warning: At present, Bitmessage gets confused if you use both the API and the UI to make addresses at the same time.
|getDeterministicAddress||<passphrase> <addressVersionNumber> <streamNumber>||0.3.1||Similar to createDeterministicAddresses except that the one address that is returned will not be added to the Bitmessage user interface or the keys.dat file. passphrase should be base64 encoded. addressVersionNumber should be set to 3 or 4 as these are the only ones currently supported. streamNumber must be set to 1 as this is the only one currently supported.
Returns a single address.
Warning: At present, Bitmessage gets confused if you use both this API command and the UI to make addresses at the same time.
||0.2.7||Does not include trashed messages. Returns a list of objects with these properties:
The msgid is the same as the hash of the message (analogous to the TXID in Bitcoin) thus it is shown in hex as that is the de facto standard. The base64 encoding Bitmessage uses includes line breaks including one on the end of the string.
||0.2.7||Returns a list of msgids of all Inbox messages with there properties:
|getInboxMessageByID||<msgid> [read]||0.4.0||Returns an object with these properties:
Optionally sets the specific message to have a read status of 'read' (bool).
The msgid is the same as the hash of the message (analogous to the TXID in Bitcoin) thus it should be given in hex as that is the de facto standard. The base64 encoding Bitmessage uses includes line breaks including one on the end of the string.
|getSentMessageByAckData||<ackData>||0.3.4||Returns an object with these properties:
|getAllSentMessages||0.3.4||Returns an object with these properties:
|getSentMessageByID||<msgid>||0.3.4||Returns an object with these properties:
|getSentMessagesBySender||<fromAddress>||0.3.4||Returns a list of objects with these properties:
|trashMessage||<msgid>||0.2.7||returns a simple message saying that the message was trashed assuming it ever even existed. Prior existence is not checked. msgid is encoded in hex just like in the getAllInboxMessages function.|
|sendMessage||<toAddress> <fromAddress> <subject> <message> [encodingType]||0.2.7||returns ackdata encoded in hex. subject and message must be encoded in base64 which may optionally include line breaks. If used, the encodingType must be set to 2; this is included for forwards compatibility.|
|sendBroadcast||<fromAddress> <subject> <message> [encodingType]||0.2.7||returns ackData encoded in hex. subject and message must be encoded in base64. If used, the encodingType must be set to 2; this is included for forwards compatibility.|
|getStatus||<ackData>||0.3.0||returns one of these strings: |
|listSubscriptions||0.4.0||Returns a list of objects with these properties:
|addSubscription||<address> [label]||0.3.1||Subscribe to an address. label must be base64-encoded.|
|deleteSubscription||<address>||0.3.1||Unsubscribe from an address. The program does not check to see whether you were subscribed in the first place.|
|listAddressBookEntries||0.4.0||Returns a list of objects with these properties:
|addAddressBookEntry||<address> <label>||0.4.0||Add an entry to your address book. label must be base64-encoded.|
|deleteAddressBookEntry||<address>||0.4.0||Delete an entry from your address book. The program does not check to see whether it was there in the first place.|
|trashSentMessageByAckData||<ackData>||0.4.0||Trashes a sent message based on its ackdata. ackData should be encoded in hex. Returns a simple message saying that the message was trashed assuming it ever even existed. Prior existence is not checked.|
|createChan||<passphrase>||0.4.2||Creates a new chan. passphrase must be base64 encoded. Outputs the corresponding Bitmessage address.|
|joinChan||<passphrase> <address>||0.4.2||Join a chan. passphrase must be base64 encoded. Outputs "success"|
|leaveChan||<address>||0.4.2||Leave a chan. Outputs "success". Note that at this time, the address is still shown in the UI until a restart.|
|deleteAddress||<address>||0.4.2||Permanently delete an address from Your Identities and your keys.dat file. Outputs "success". Note that at this time, the address is still shown in the UI until a restart.|
|decodeAddress||<address>||0.4.2||Returns an object with these properties:
|addAddressToBlackWhiteList||<address> [label]||0.4.5||Add an entry to your black or white list- whichever you are currently using. label must be base64-encoded.|
|removeAddressFromBlackWhiteList||<address>||0.4.5||Delete an entry from your black or white list- whichever you are currently using (but not both).|
Note: If the minimum required version is higher than page is obsolete then the code is available in source but not yet available in a compiled binary.
Possible error values
Here are the various error numbers and descriptions you might see.
