Invoices

Upload invoice
The upload invoice endpoint will return a "reference" response header which is used to identify the invoice in subsequent requests.
This is useful in scenarios where an image is returned instead of the invoice response model.
Invoices sent by merchants are typically short-lived, and are expected to be recycled various times throughout a business day. This often means that invoice references used by a business are not unique to a single invoice.
The default representation will only be active for 1 hour.
In the event that your business recycles invoices and communicates recycled invoice references to the Zapper Platform, payment notifications returned may vary.
LineItems
Line-items can be included in your invoices, allowing you to take advantage of Zapper's itemised vouchers and better promote specific items.

Representations
Representation-Types
Representation-Type
Description
Limitations
Category
zappercode/v2
A legacy Invoice Representation which includes the merchant Info, invoice amount and other metadata such as instructions to enable/disable certain client features (e.g. show tip and split bill options)
Does not support line items
QR Code
zappercode/v6
Similar to v2 in that the code includes some of the invoice information within it, however, the invoice details are encoded and compressed which allows the inclusion of line-items (facilitating line-item voucher support)
Can grow into a dense QR Code which may be difficult to scan with low end cameras.
QR Code
triggercode/transient
A short string with only an identifier to a backing value on server side, i.e. No other information is stored within the code. QR Codes are less dense and easier to scan as a result. Ideal for use in restaurants when a code of limited length is printed onto a bill
​
Fetches Invoice from Zapper server before displaying to user
Only active for 1 hour
QR Code
triggercode/dynamic
A physical printed code with only an identifier to a backing value. This code is pre-provisioned on a stand and provided to the merchant. The merchant can then assign the code to a specific site/till.
Invoice uploads will automatically update/clear the server side backing value. This is ideal for retail scenarios where physical codes are set up on the counters at each till.

QR Code
deeplink/zappercode/v2
A special shareable link including a v2 Zapper Code that when clicked, takes the user to the pay screen of the Zapper App
​
Some older devices do not link directly through to app
Does not support line items.

deeplink/zappercode/v6

Supported Accept Headers For Representation Categories
If the Accept header is set to "application/json", the Representation-Type header is ignored
If the Accept header is set as "text/plain", but the caller requires a QR Code, either generate the QR Code from the string that is returned or change the accept header to "image/svg+xml" or "image/png" to have the QR Code generated by the invoice service.
For Representations categorized as "Link", only the text/plain header is supported.
