Unofficial DeGiro stock broker java API client.
This library implements all DeGiro primitive operations. It provides the same functionality of DeGiro web and makes it easier to automate your portfolio management.
VERY IMPORTANT: DeGiro could change their API in any moment so use this library at your own risk.
If you have any questions, please open an issue.
Maven artifact not yet release, in the meantime use jitpack.io:
Add jitpack.io repository:
<repositories>
<repository>

Add dependency:
<dependency>

Maven artifact not yet release but in the mean time use jitpack:
Add the artifact to your project and then use DeGiroFactory to obtain a DeGiro instance.
DCredentials creds = new DCredentials() {
@Override
public String getUsername() {
return "YOUR_USERNAME";
}
@Override
public String getPassword() {
return "YOUR_PASSWORD";
}
};
DeGiro degiro = DeGiroFactory.newInstance(creds);If you don't want to create a new DeGiro session on each execution instantiate a DeGiro object with a DPersistentSession. DeGiro API will try to reuse session values (expired session will be renewed automatically).
DeGiro degiro = DeGiroFactory.newInstance(creds, new DPersistentSession("/path/to/session.json"));For most operation Degiro web portal use a delta sync update polling mechanism to keep web view live data. Web portal usualy request delta sync for multiple sections/tables at once to minimize numbers of requests and lag. I recommend you do the same.
Deliberately library client class does not handle state management for the delta sync mechanist and only expose received delta sync operations. This way one can implement its own method to save records, and react to changes.
//use some kind of repository ...
final Map<String, DOrder> orders = new HashMap<>();
//use a repository for each of the available sections: portfolio, totalPortfolio, orders, historicalOrders, transactions, alerts, cashFunds;
//a location to keep track of last update token received (or processed)
List<DUpdateToken> tokens = new ArrayList<>(DUpdateToken.allSections());
//in some kind of loop do the following:
//fetch detla updates from tokens to current state
final DUpdates dUpdates1 = deGiro.updateAll(tokens);
//handle received updates with eventual changes (create/update/delete)
for (DUpdate<DOrder> update : dUpdates.getOrders().getUpdates()) {
switch (update.getType()) {
case DELETED:
orders.remove(update.getId());
case CREATED:
orders.put(update.getId(), update.getNew());
case UPDATED:
//if in-place update can't be used, use DOrder#copy() first to apply updates on object copy
update.update(orders.get(update.getId()));
}
}
//handle other sections (portfolio, totalPortfolio, orders, historicalOrders, transactions, alerts, cashFunds) the same way
//record last used update tokens.
tokens = dUpdates1.getTokens();// Search products by text, signature:
// DProductSearch searchProducts(String text, DProductType type, int limit, int offset);
DProductSearch ps = degiro.searchProducts("telepizza", DProductType.ALL, 10, 0);
for (DProduct product : ps.getProducts()) {
System.out.println(product.getId() + " " + product.getName());
}
// Get product info by id, signature:
// DProducts getProducts(List<String> productIds);
List<String> productIds = new ArrayList<>();
//be aware that in some cases productId is a number and others a string. You can safly convert number to String for this request
productIds.add("1482366"); // productId obtained in (orders, portfolio, transactions, searchProducts....)
degiro.getProducts(productIds);
DProductDescriptions products = degiro.getProducts(productIds);
for (DProductDescription value : products.getData().values()) {
System.out.println(value.getId() + " " + value.getName());
}Some product fields may be incrementally update baes on subscriptions.
IMPORTANT: Product subscription must be requested using vwdId present in product fields and not product id.
//get poller instance
PricePoller poller = degiro.getPricePoller();
// Create a vwdIssueId list. Note that vwdIssueId is NOT a productId (vwdIssueId is a DProduct field).
List<Long> vwdIssueIds = new ArrayList<>(1);
vwdIssueIds.add(280099308L); // Example product vwdIssueId
poller.subscribe(vwdIssueIds); // Callable multiple times with different products.
//poller will keep trak of subscribed products and renew session if requiered
//now one must use some kind of scheduler to get price updates
//usualy web platform does call updates every seconds or so
Collection<DPrice> updates = poller.poll();
//Clear all subscriptions:
poller.unsubscribeAll();A schedule of some king should be used to poll updates but its implementation is out of the scope of this library.
Orders are placed in two steps: check order (to ensure order factibility) and confirmation. When DConfirmation status is 0 then the order is placed successfully.
// Generate a new order. Signature:
// public DNewOrder(DOrderAction action, DOrderType orderType, DOrderTime timeType, long productId, long size, BigDecimal limitPrice, BigDecimal stopPrice)
DNewOrder order = new DNewOrder(DOrderAction.SELL, DOrderType.LIMITED, DOrderTime.DAY, 1482366, 20, new BigDecimal("4.5"), null);
DOrderConfirmation confirmation = degiro.checkOrder(order);
if (!Strings.isNullOrEmpty(confirmation.getConfirmationId())) {
DPlacedOrder placed = degiro.confirmOrder(order, confirmation.getConfirmationId());
if (place.getStatusId() != 0) {
throw new RuntimeException("Order not placed: " + place.getStatusText());
}
}Order update example:
// Update an order. Signature:
// DPlacedOrder updateOrder(DOrder order, BigDecimal limit, BigDecimal stop);
DPlacedOrder updated = degiro.updateOrder(order, new BigDecimal("0.04"), null); // obtained in getOrders()
if (updated.getStatusId() != 0) {
throw new RuntimeException("Order not updated: " + updated.getStatusText());
}Order delete example:
DPlacedOrder deleted = degiro.deleteOrder(orderId); // orderId obtained in getOrders()
if (deleted.getStatusId() != 0) {
throw new RuntimeException("Order not deleted: " + deleted.getStatusText());
}
