order_tag such as enum:STRATEGY_DCA during order placement. The order tag value can be either a plain referral code or enum:<enum_id>. The enum_id is the fee config identifier; to apply custom trading fee per order, the order tag sent on an order must include the enum: prefix. Use this guide when your DEX, strategy backend, vault, bot flow, campaign, or broker-specific UX needs fee rules that differ by order category.
This guide explains the integration flow and links to the API reference pages. It intentionally does not duplicate the full API specs.
Integration Flow
Create order tags
Builder admins create one or more order tag fee configs with a
default_fee_rate and optional pair_overrides.Use POST /v1/broker/order_enum.Expose active order tags to your DEX
Your DEX or backend fetches active order tag configs with
broker_id so it can decide which tag to apply and disclose the extra fee to users.Use GET /v1/public/broker/order_enums.Apply the order tag during order placement
Set
order_tag to enum:<enum_id> on supported order creation requests, for example enum:STRATEGY_DCA.Use POST /v1/order, POST /v1/batch-order, or POST /v1/algo/order.Reconcile order and trade results
Read
order_tag on orders for attribution and use trade-level fee fields for reporting and reconciliation.Use the order and trade APIs listed below.Public DEX Integration
Use GET/v1/public/broker/order_enums from your DEX or backend service to discover available order tag fee configs for a builder.
The public list endpoint is unauthenticated and takes broker_id as a query parameter:
symbol, enum_id, and include_archived.
Fee Disclosure
Whenorder_tag uses the enum:<enum_id> format, the matching order tag fee config applies an additional custom trading fee on top of the standard fee schedule. The enum: prefix is required for custom trading fee per order. This is different from a plain referral-code order_tag, which is treated as referral attribution and does not apply the custom trading fee per order.
The order tag fee is charged in addition to the user’s existing trading fee:
default_fee_rate is the fallback fee rate for the order tag. pair_overrides lets builders override that fallback for specific symbols, so one order tag can charge different additional fee rates by market. If pair_overrides includes the order symbol, use that symbol-specific order tag fee rate. Otherwise, use default_fee_rate. Display the order tag fee separately from the standard trading fee so users understand both components before placing an order.
Applying Order Tags to Orders
Setorder_tag on supported order creation APIs:
| API | Integration note |
|---|---|
POST /v1/order | Set order_tag on the order request body. |
POST /v1/batch-order | Set order_tag on each order object inside orders that should use the order tag fee config. |
POST /v1/algo/order | Set order_tag on the algo order request body. |
order_tag supports two formats:
| Format | Example | Behavior |
|---|---|---|
| Referral code | REFERRAL2026 | Plain string. Overrides the referral relationship. |
| Order tag fee config | enum:STRATEGY_DCA | Applies an additional custom trading fee on top of the standard fee schedule and preserves referral. |
order_tag is immutable after order placement. To change the tag on an open order, cancel the order and place a new one with the intended order_tag.
Returned Order and Trade Data
Use order APIs for attribution and UI display:| API | Relevant data |
|---|---|
GET /v1/order/{order_id} | Returns order_tag on the order. |
GET /v1/client/order/{client_order_id} | Returns order_tag on the order. |
GET /v1/orders | Returns order_tag on each order row. |
| API | Relevant data |
|---|---|
GET /v1/trades | Returns fee, order_enum_fee, and order_enum_fee_rate on trade rows. |
GET /v1/trade/{trade_id} | Returns fee, order_enum_fee, and order_enum_fee_rate. |
GET /v1/order/{order_id}/trades | Returns order trades with order tag fee fields. |
GET /v1/algo/order/{order_id}/trades | Returns algo order trades with order tag fee fields. |
fee includes both the standard trading fee and the order tag fee:
Admin Operations
Admin endpoints require standard Orderly signed request headers and should only be called from secured builder admin tooling or backend services.| Action | API reference |
|---|---|
| Create order tag | POST /v1/broker/order_enum |
| Update order tag | PUT /v1/broker/order_enum/{enum_id} |
| List order tags with usage stats | GET /v1/broker/order_enums |
| Get single order tag with usage stats | GET /v1/broker/order_enum/{enum_id} |
| Archive order tag | POST /v1/broker/order_enum/archive |
| Unarchive order tag | POST /v1/broker/order_enum/unarchive |
Data Model Notes
| Field | Description |
|---|---|
enum_id | Unique uppercase fee config ID, for example STRATEGY_DCA. The order tag value must be enum:<enum_id>, for example enum:STRATEGY_DCA. |
status | active or archived. |
default_fee_rate | Default fee rate applied when no symbol override exists. |
pair_overrides | Optional map of symbol to fee rate. |
created_time | Creation timestamp in milliseconds. |
updated_time | Last update timestamp in milliseconds. |
total_orders, total_volume, and total_fees_collected.
Implementation Notes
- Treat
enum_idas immutable. If the classification semantics change, create a new fee config rather than reusing a misleading ID. - Use uppercase alphanumeric characters and underscores only, with a maximum
enum_idlength of 31 characters. - The full
order_tagvalue must fit within 36 characters, including the requiredenum:prefix. - Archived order tags should not be used for new orders.
- Do not expose admin endpoints, account credentials, or signing keys in the DEX frontend.
- Cache public order tag responses briefly to avoid rate limit pressure, but refresh when admin configuration changes need to be reflected quickly.
- Fee configuration is evaluated at execution time, so updates can affect later fills of existing open orders.
