Set order bumps on a checkout page

Order bumps were the one part of a checkout you had to go back into the funnel builder for. show_page_step.bump_product_ids and show_page_step.bump_preheadline now sit alongside the existing show_page_step.product_ids on POST /api/v2/workspaces/:workspace_id/pages and PATCH /api/v2/pages/:id, so you can build the main offer and its bump in the same request.

Bump attachment behaves like product attachment: additive, all-or-nothing within a batch, and never removing what is already there. The response's show_page_step.products lists everything the step sells in display order, each entry carrying bump and bump_preheadline, so you can read back which products are bumps without a second call.

Agent examples: build a checkout page and its order bump in one pass · change a bump's pre-headline copy across a set of pages without opening the builder.
