Supported event types

The V2 API expects at minimum the following event types:

page_view

Page visits across your site

view_item

Product details page

purchase

Purchase transactions

The API also supports the following optional event types:

view_item_list

Product list viewed

select_item

Item selected from a list

add_to_cart

Item added to cart

remove_from_cart

Item removed from cart

view_cart

Cart page viewed

add_to_wishlist

Item added to wishlist

remove_from_wishlist

Item removed from wishlist

begin_checkout

Checkout started

The API is extensible — you can send any event_name value beyond the ones listed above, and Dema can build custom metrics on top of it. The available fields per event are defined by the event data schema.

Prerequisites

Your unique Dema ID, formatted as DV-XXXXXXXXXXXXXXXXXXXXXXXX

Response

The API returns an HTTP 200 status code with an empty response body on success.

Request details

Endpoint

URL: https://tracker.dema.ai/api/track

HTTP methods

Both GET and POST methods are supported.

GET requests have a practical limit of approximately 8 KB of data due to URL length restrictions. For larger payloads, use the POST method.

Required request parameters

Parameter	Description
`i`	Your unique Dema ID.
`uid`	Unique user ID for the event, a UUID managed server-side. Must be a valid UUIDv4 string. Should remain consistent across events for the same user.
`_nc`	No-cache parameter. Current timestamp in milliseconds since epoch.
`v`	Version of your tracking integration (e.g., `"2.0.0"`). Use your own versioning scheme.

Event details

For GET requests, event details are passed as a URL-encoded JSON string in the m query parameter. For POST requests, event details are sent as a JSON body with the Content-Type: application/json header. Event details must conform to the TrackedEventData schema. See the Event data schema reference section for the full schema and field descriptions.

Event examples

page_view

A basic page view event:

{
  "event_name": "page_view",
  "page_location": "https://example.com/summer-collection",
  "page_referrer": "https://google.com/search?q=summer+collection",
  "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36",
  "ip": "10.0.0.1"
}

view_item

Sent when a user views a product detail page:

{
  "event_name": "view_item",
  "page_location": "https://example.com/summer-collection/product1234",
  "page_referrer": "https://example.com/summer-collection",
  "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36",
  "ip": "10.0.0.1",
  "items": [
    {
      "index": 0,
      "product_id": "1234",
      "price": 199.99
    }
  ],
  "currency": "EUR"
}

On a product display page, you should send both a page_view event and a view_item event. This is different from the deprecated V1 API, where a single pageview event covered both.

Event fields

Required fields

event_name

string

required

Name of the tracked event (e.g., page_view, view_item, purchase).

Page & navigation fields

Client & location fields

user_agent

string

User agent string of the client sending the tracked event.

string

IP address of the client. Used to resolve location fields if not provided explicitly.

country

string

Two-letter ISO 3166-1 alpha-2 country code. When provided, overrides the country resolved from the IP address.

region

string

Region (state/province). When provided, overrides the region resolved from the IP address.

city

string

City. When provided, overrides the city resolved from the IP address.

zip_code

string

ZIP/postal code. When provided, overrides the ZIP/postal code resolved from the IP address.

latitude

number

Latitude coordinate. When provided, overrides the latitude resolved from the IP address.

longitude

number

Longitude coordinate. When provided, overrides the longitude resolved from the IP address.

Event detail fields

type

string

Event-specific type. For example, for order events the type can be set to EXCLUDED to prevent the order from appearing in the platform.

order_id

string

Identifier of the order associated with the tracked event.

customer_id

string

Identifier of the customer. Typically an email address, but can be any consistent identifier.

currency

string

Three-letter ISO 4217 currency code (e.g., EUR, USD).

total

number

Total value of the transaction, including items, tax, and shipping.

tax

number

Total tax amount for the transaction including shipping tax.

shipping

number

Shipping cost for the transaction including tax.

payment_provider

string

Payment provider used for the transaction.

shipping_provider

string

Shipping provider used for the transaction.

cart_id

string

Identifier of the shopping cart.

wishlist_id

string

Identifier of the wishlist.

items

array

List of items associated with the event. See item fields below.

vouchers

array

List of vouchers applied to the transaction. See voucher fields below.

Custom attributes

custom_attribute_1 – custom_attribute_20

string

Text value for the custom event-level attribute slot (slots 1–20). Use this field when the attribute is a text dimension.

custom_attribute_1_float – custom_attribute_20_float

number

Numeric value for the custom event-level attribute slot. Use this field when the attribute is a numeric or monetary metric.

custom_attribute_1_meta – custom_attribute_20_meta

object

Controls which slot Dema reads for this attribute and how the value is processed. Without meta, the string slot is treated as a plain text dimension. Set dataType to NUMERIC or MONETARY to have Dema read the float slot as a metric — monetary values are then converted to the merchant currency using currency as the source currency, and SPLIT_ACROSS_ORDER_LINES can be added to features to distribute an order-level value across order lines. See CustomAttributeMeta below.

Item fields (`items[]`)

Required fields

product_id

string

required

Product identifier used for identifying the product in the external system.

Optional fields

index

integer

Index of the item line in the tracked event. Event context specific — e.g., in select_item it represents the item’s position in the list; in add_to_cart it represents the item’s position in the cart.

variant_no

string

Identifier of the specific product variant.

quantity

number

Quantity of the item line.

price

number

Price of a single item unit.

warehouse

string

Warehouse associated with the item. Use the same warehouse names consistently across orders, inventory, and indeliveries — we recommend using human-readable names rather than internal IDs.

custom_attribute_1 – custom_attribute_20

string

Text value for the custom item-level attribute slot (slots 1–20). Use this field when the attribute is a text dimension.

custom_attribute_1_float – custom_attribute_20_float

number

Numeric value for the custom item-level attribute slot. Use this field when the attribute is a numeric or monetary metric.

custom_attribute_1_meta – custom_attribute_20_meta

object

Voucher fields (`vouchers[]`)

Required fields

code

string

required

The voucher’s redemption code.

Optional fields

name

string

Voucher name.

discount

number

Value of the voucher discount.

type

string

Type of the discount.

CustomAttributeMeta

The custom_attribute_N_meta companion controls which slot Dema reads for the attribute and how it is processed. Without it, the string slot is used as a plain text dimension and the float slot is ignored.

Field	Type	Description
`dataType`	string	`TEXT` — read the string slot as a text dimension (default when meta is omitted). `NUMERIC` — read the float slot as a unit-less metric. `MONETARY` — read the float slot as a monetary metric and convert to the merchant currency using `currency`.
`currency`	string	ISO 4217 source currency of the float value (e.g. `EUR`). Required when `dataType` is `MONETARY`; ignored otherwise.
`features`	string[]	Opt-in processing flags. `SPLIT_ACROSS_ORDER_LINES` — event-level attributes only. Distributes an order-level value across order lines by contributing weight (the same mechanism used for shipping and logistic costs). Has no effect on item-level attributes.

Additional notes

Ensure all URL parameters are properly URL-encoded when using GET requests.
The uid (unique user ID) must be managed server-side. This ID should be a valid UUIDv4 and remain consistent across events to accurately track user behavior.
