Connections
The connections endpoints allow you to automatically connect to a token network as well as leave a token network by closing and settling all open channels.
HTTP Method | Resource | Description |
GET | Details of all joined token networks | |
PUT | Join a token network | |
DELETE | Leave a token network |
Currently all API calls are blocking. In case of long running API calls like joining or leaving a token network, if any concurrent API calls are made they will be queued.

get
http://localhost:5001/api/v1/connections
Each key in the JSON response object is a token address for which you have open channels.

The value for the token address key is an object containing:
- "funds", a string of the token amount from your last connect request
- "sum_deposits", a string of the sum of deposits in all currently open channels
- "channels", a string of all channels currently open for the specific token

Calling this endpoint lets you join the token network for the specified token and automatically open channels.
If you have already joined the token network for the specified token a call to this endpoint can be made to change the funds allocated in the token network.
The request might take some time and will only return once all blockchain calls for opening and/or depositing to a channel have been completed.

{"funds": "1337"}
If the number of channels provided as a value for initial_channel_target is greater than the current number of peers in the token network the funds will still get split according to the value you provided.
This means that if you have funds of 100 tokens and want to open 4 channels but there are only 3 peers in the network then 15 tokens will get distributed for the 3 channels while the remaining 15 will be used for opening a 4th channel as soon as one more peer becomes available.
