The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such model

This instance publishes no model under that name. It may have been renamed, or no operation this installation serves uses it.

Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-22 22:52 UTC.

API reference Models

HppPresentationMode

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

How the public hosted payment page presents itself for a session: as a standalone page the cardholder navigates to, or as a chrome-less surface mounted inside a merchant-site iframe. This governs page chrome only (outer surface background, full-viewport height, page padding). It never changes the session flow, the fields collected, or any compliance content: consent capture, the NACHA WEB authorization, the convenience-fee disclosure, and the confirmation panel render identically in both modes.

Values

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
Standalone The default, historical behavior: a full standalone page with the surface background, full-viewport minimum height, and the standard outer page padding. null (legacy sessions) resolves here.
Embedded A chrome-less compact presentation for mounting inside a merchant-site iframe: no standalone page surface or full-viewport height, tight paddings, and narrow-width behavior that stays readable down to a 320 px viewport without horizontal scrolling.

Your work on this page is still here. Retrying keeps it; reloading starts the page again.

The server no longer holds this page's state, so it has to be loaded again.
