Tracking a Status of the Order
After the transaction has been successfully included in the source blockchain, it is time to retrieve the status of an order created within the given transaction. There are several ways to track the status of the trade.
The first way is /filteredList method of dedicated stats-api that allows retrieving the history of all trades performed by the wallet and their statuses. Check redoc for more details. Stats-API Swagger is available at this link.
Example of trade history for address 0xB779DaeAD6031Ef189cAD4Ac438c991Efe7635A7:
To understand the data structure and how trade history can be reflected in your app, you can check the DLN trade history page of deExplorer which is using this endpoint to obtain data.
In case detailed information on one specific trade is needed, /api/Orders/creationTxHash/ endpoint of DLN API can be used. It returns the status and all the order parameters that are reflected on the order page of deExplorer.
Example of how to retrieve DLN trade details based on orderID: https://stats-api.dln.trade/api/Orders/creationTxHash/0x3fe11542154f53dcf3134eacb30ea5ca586c9e134c223e56bbe1893862469bc5 and Link to the same order in deExplorer
If multiple DLN orders were created in the same transaction, /creationTxHash will return information about the first one only
If multiple trades were created in a single transaction, there is an endpoint which returns the list of orderIds of the orders that were created by the given transaction: /v1.0/dln/tx/:hash/order-ids.
Let's say, a transaction 0x40ee524d5bb9c4ecd8e55d23c66c5465a3f137be7ae24df366c3fd06daf7de7e has been submitted to the BNB Chain. Calling the endpoint:
gives an array with only one orderId within it:
An array instead of a single orderId is returned because a top-level transaction may perform several calls to DLN, thus leading to multiple order creation.
After the orderId has been revealed, it can be used to track the order's status by orderId specifically (instead of creation txHash). Use the GET /api/Orders/{orderId} endpoint supplying the given orderId. Calling the endpoint:
gives a status for the given order:
The order may have different statuses across its lifecycle, but the most important are Fulfilled, SentUnlock and ClaimedUnlock — all indicating that the order has been successfully fulfilled, and a recipient has received a precise amount of the output token.
If an order is in any of Fulfilled, SentUnlock, or ClaimedUnlock statuses, it can be displayed as fulfilled for the end-user.
The affiliate fee (if set) that has been accrued during order creation is transferred to the affiliateFeeRecipient when the ClaimedUnlock status is reached.
This is a complete set of all possible statuses that an order may have, according to the DLN API:
