This endpoint allows you to send order data to LoudCrowd so that orders can be properly attributed to creators and commissions can be calculated. LoudCrowd uses this data to identify which orders are attributed to creators and calculate the commissions earned from each order.

Note: The Events API is a single endpoint (POST https://api.loudcrowd.com/event/ecomm). Behavior is selected via the X-LC-TOPIC header (ORDER_CREATE, ORDER_UPDATE, ORDER_CANCEL). For refunds/returns specifics, see the Submit Return Event guide.

Prerequisites

Before using this endpoint, ensure that:

LoudCrowd SDK is installed on your ecommerce site
LoudCrowd shoppable program has been set up to generate affiliate links

Authentication

The API uses HMAC-SHA256 signature authentication. Each request must include:

X-LC-SHOP-ID: Your LoudCrowd internal shop ID (found in the LoudCrowd dashboard)
X-Signature: SHA256 hexdigest of the UTF-8 encoded JSON payload
X-LC-TOPIC: Event type (ORDER_CREATE, ORDER_UPDATE, or ORDER_CANCEL)
Content-Type: application/json

Important Notes

Refund Line Item IDs

The refund_line_item_id is crucial for LoudCrowd to distinguish between new refunds and existing ones. These IDs must be:

Unique for each line item returned in the order
Consistent between multiple order update events
Different for each refund entity in a single order

Providing lc_anon_id

If you haven't configured the order confirmation script, you can get the tracking ID using:

window.loudcrowd.identifyDevice();

Gross Taxation Policy

For regions using gross taxation (tax included in price):

Amount: Send the gross amount (item price with tax included)
Tax: Send the VAT amount

Use this formula to extract tax from gross amounts:

tax = round(amount - (amount / (1 + tax_rate)), 2)

Where tax_rate is the decimal representation (e.g., 0.2 for 20% VAT).

Best Practices

Security: Keep your pre-shared key secret and never store it in source code
Error Handling: Always check for 200 status code responses and handle 400+ errors
Logging: Build internal logging around status code errors
Timing: Send events as soon as orders are placed
Consistency: Build a back-fill pipeline alongside the events API
Validation: Ensure all required fields are present and properly formatted
