You deposit in a channel by making a PATCH request to the channels
endpoint that includes:
The address of the W-ETH token as a path parameter.
The address of the partner node as a path parameter.
The amount of tokens you want to deposit in the channel as a body parameter.
curl -i -X PATCH \http://localhost:5001/api/v1/channels/0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2/<partner_address> \-H 'Content-Type: application/json' \--data-raw '{"total_deposit":"4000"}'
Notice how we are specifying the total_deposit
in the request and not only the amount we want to "top-up" with. This means that if we initially deposited
2000 WEI and want to increase the amount with 2000 we would need to make a total deposit of 4000 WEI.
This is done to prevent requests that are sent repeatedly (by accident or as part of an attack) from having any further consequences.
