Below is an explanation of what each action does: - `take` - If the order has not expired and is still public, on a successful take, you get the same response as if `GET /order` was called and the status of the order was `3` (waiting for taker bond) which means `bond_satoshis` and `bond_invoice` are present in the response as well. Once the `bond_invoice` is paid, you successfully become the taker of the order and the status of the order changes. - `pause` - Toggle the status of an order from `1` to `2` and vice versa. Allowed only if status is `1` (Public) or `2` (Paused) - `update_invoice` - This action only is valid if you are the buyer. The `invoice` field needs to be present in the body and the value must be a valid LN invoice as cleartext PGP message signed with the robot key. Make sure to perform this action only when both the bonds are locked. i.e The status of your order is at least `6` (Waiting for trade collateral and buyer invoice) - `update_address` - This action is only valid if you are the buyer. This action is used to set an on-chain payout address if you wish to have your payout be received on-chain. Only valid if there is an address in the body as cleartext PGP message signed with the robot key. This enables on-chain swap for the order, so even if you earlier had submitted a LN invoice, it will be ignored. You get to choose the `mining_fee_rate` as well. Mining fee rate is specified in sats/vbyte. - `cancel` - This action is used to cancel an existing order. You cannot cancel an order if it's in one of the following states: - `1` - Cancelled - `5` - Expired - `11` - In dispute - `12` - Collaboratively cancelled - `13` - Sending satoshis to buyer - `14` - Successful trade - `15` - Failed lightning network routing - `17` - Maker lost dispute - `18` - Taker lost dispute Note that there are penalties involved for cancelling a order mid-trade so use this action carefully: - As a maker if you cancel an order after you have locked your maker bond, you are returned your bond. This may change in the future to prevent DDoSing the LN node and you won't be returned the maker bond. - As a taker there is a time penalty involved if you `take` an order and cancel it without locking the taker bond. - For both taker or maker, if you cancel the order when both have locked their bonds (status = `6` or `7`), you loose your bond and a percent of it goes as "rewards" to your counterparty and some of it the platform keeps. This is to discourage wasting time and DDoSing the platform. - For both taker or maker, if you cancel the order when the escrow is locked (status = `8` or `9`), you trigger a collaborative cancel request. This sets `(m|t)aker_asked_cancel` field to `true` depending on whether you are the maker or the taker respectively, so that your counterparty is informed that you asked for a cancel. - For both taker or maker, and your counterparty asked for a cancel (i.e `(m|t)aker_asked_cancel` is true), and you cancel as well, a collaborative cancel takes place which returns both the bonds and escrow to the respective parties. Note that in the future there will be a cost for even collaborativelly cancelling orders for both parties. - `confirm` - This is a **crucial** action. This confirms the sending and receiving of fiat depending on whether you are a buyer or seller. There is not much RoboSats can do to actually confirm and verify the fiat payment channel. It is up to you to make sure of the correct amount was received before you confirm. This action is only allowed when status is either `9` (Sending fiat - In chatroom) or `10` (Fiat sent - In chatroom) - If you are the buyer, it simply sets `fiat_sent` to `true` which means that you have sent the fiat using the payment method selected by the seller and signals the seller that the fiat payment was done. - If you are the seller, be very careful and double check before performing this action. Check that your fiat payment method was successful in receiving the funds and whether it was the correct amount. This action settles the escrow and pays the buyer and sets the the order status to `13` (Sending satohis to buyer) and eventually to `14` (successful trade). - `undo_confirm` - This action will undo the fiat_sent confirmation by the buyer it is allowed only once the fiat is confirmed as sent and can enable the collaborative cancellation option if an off-robosats payment cannot be completed or is blocked. - `dispute` - This action is allowed only if status is `9` or `10`. It sets the order status to `11` (In dispute) and sets `is_disputed` to `true`. Both the bonds and the escrow are settled (i.e RoboSats takes custody of the funds). Disputes can take long to resolve, it might trigger force closure for unresolved HTLCs). Dispute winner will have to submit a new invoice for value of escrow + bond. - `submit_statement` - This action updates the dispute statement. Allowed only when status is `11` (In dispute). `statement` must be sent in the request body and should be a string. 100 chars < length of `statement` < 5000 chars. You need to describe the reason for raising a dispute. The `(m|t)aker_statement` field is set respectively. Only when both parties have submitted their dispute statement, the order status changes to `16` (Waiting for dispute resolution) - `rate_platform` - Let us know how much you love (or hate 😢) RoboSats.
