Reseller Orders

These endpoints allow resellers to generate promotion codes that require payment (bijbetaling), check code status, and retrieve all codes associated with a customer email address or customer identifier.

POST/promotion/generate-payment-code

Generate payment code

Creates a promotion code that requires payment before activation. The payment amount is calculated based on the product price minus any scanner discount configured on the device.

Required headers

This API requires a Device Token. These tokens are generated in the dashboard by navigating to "Scanners" and clicking the key icon.

Name
Authorization
Type
string
Description
Bearer token of the authenticated device.

Request body

Name
organization_identifier
Type
string
Description
Identifier of the organization.
Name
promotion_identifier
Type
string
Description
UUID of the promotion.
Name
product_id
Type
integer
Description
ID of the product to be purchased.
Name
location_id
Type
integer
Description
ID of the location where the code will be activated.
Name
email
Type
email
Description
Customer email address. If provided, a user account will be created or linked. Either email or customer_identifier must be provided.
Name
customer_identifier
Type
string
Description
Unique external identifier for the customer (e.g., loyalty ID, customer number). Used to track customers across channels without requiring an email address. Either email or customer_identifier must be provided.
Name
discount
Type
number
Description
Per-request discount percentage applied to the product price (0-100). When supplied, this value is used in place of the device's default channel_discount for this transaction. Hard-capped by the device's channel_kickback margin — requests where discount > channel_kickback are rejected with 422.

Behavior

Validates the device, organization, and promotion
Resolves the effective discount: if discount is supplied it replaces the device's channel_discount for this transaction; otherwise the device default is used
Rejects with 422 when the supplied discount exceeds the device's channel_kickback
Calculates payment amount: price - (price * effective_discount / 100)
Creates or links user account if email is provided
If customer_identifier is provided, creates or links external_user record for cross-channel tracking
Generates a unique promotion code with payment requirement
Creates Mollie payment directly and returns checkout URL for immediate payment
Stores external_user_id in promotion_codes table for customer_identifier lookups
Code expires in 91 days from creation

POST/promotion/check-code-status

Check code status

Retrieves the current status of a promotion code, including activation status, redemption status, payment status, and location information.

QR Code / Barcode Availability

The qr_image_url field is only included in the response when all of the following conditions are met:

Code is activated (status.activated = true)
Code is paid (status.paid = true OR no payment required)
Code is not redeemed (status.redeemed = false)

This ensures the code image is only shown when the code is ready to be scanned at a location.

QR vs Barcode

The format follows the device configured at the location the customer activated against — not the requesting device. Resolution order:

First device on code.location_id
code.device_id (fallback when location has no device)
Querying device (final fallback for legacy codes with no location bound)

Using the customer-bound device guarantees the format matches what the redemption location's scanner expects, regardless of which integration partner makes the check-code-status call.

QR Code: For standard scanning devices, returns /qrcode/{code} with the WLNT code.
Barcode: For manual entry devices (response_type = 'manual'), returns /barcode/{value}?format=svg where {value} is:
- Product's cash_register_column when code.product_id is set
- Location device's device_promotion.reference if no product reference exists
- Falls back to the WLNT code if neither is set

Image format (`/qrcode/...` and `/barcode/...`)

Both endpoints accept an optional ?format= query parameter so consumers can pick the format that renders best in their environment.

| Endpoint | Default response | Opt-in via query param | | --- | --- | --- | | /qrcode/{code} | image/svg+xml | ?format=png → image/png | | /barcode/{value} | image/png | ?format=svg → image/svg+xml |

The barcode URL returned by qr_image_url already includes ?format=svg so most consumers don't need to think about this. iOS clients (PassKit, certain in-app webviews) render PNG more reliably than SVG — append ?format=png to the returned qr_image_url (or replace the existing ?format=svg) when rendering on iOS:

const isIos = /iPad|iPhone|iPod/.test(navigator.userAgent);
let url = data.qr_image_url;
if (isIos) {
  url = url.replace(/([?&])format=svg/, '$1format=png');
  if (!url.includes('format=')) {
    url += (url.includes('?') ? '&' : '?') + 'format=png';
  }
}

Cache keys are per-variant so PNG and SVG responses don't poison each other.

POST/promotion/activate-paid-code

Activate a paid bijbetaling code

Activates a scanner-issued bijbetaling code after the customer has paid through Mollie. This endpoint exists for codes that were created via /promotion/generate-payment-code against a redemption location whose device is a barcode/manual scanner (response_type = 'manual'). Those codes are intentionally held in an inactive state after payment so the scanner can decide when they become redeemable.

For QR-code redemption devices the Mollie webhook activates the code automatically — this endpoint is not required.

Required headers

Name
Authorization
Type
string
Description
Bearer token of the authenticated scanner device. The device must belong to the supplied organization.

Request body

Name
organization_identifier
Type
string
Description

promotion_identifier
Type
string
Description
UUID of the promotion the code belongs to.
Name
code
Type
string
Description
The full WLNT-… promotion code that was returned by /promotion/generate-payment-code.

Behavior

Authenticates the device via bearer token and verifies it is bound to the supplied organization.
Looks up the code under the supplied promotion.
Refuses with 409 if the code still requires payment (bijbetaling_required is true and bijbetaling_paid is false).
Refuses with 409 if the code is already active (activation_date is set).
Stamps activation_date = now().
Sets expiration_date to now() + N days, where N is the redemption location device's staffel_redemption_days (defaults to 60 when not configured).
Once activated, /promotion/check-code-status returns the barcode/QR image URL for the code.

Response fields
