Update an existing page. Works for both internal and external (SDK) pages.

Closed Alpha note: updating an external page requires external (SDK) page access — not yet enabled for all workspaces (403 otherwise). Request access at https://developers.myclickfunnels.com/page/code-support. Internal page updates are unaffected.

Field availability depends on the page type — see PageParametersUpdate for the full breakdown. Sending an internal-only field on an external page (or external_url on an internal page) returns 422 with an explicit list of the rejected field names — never silently ignored.

sort_order (optional, top-level): Reposition the page within its funnel. Zero-based. Ignored when funnel.show_page_step_id is also provided.

funnel.show_page_step_id (optional): Swap the page onto an existing show page step. The previous page on that step becomes an orphan. Shared by both page types.

external_url (external pages only): Update the external URL. The SDK token is preserved.

show_page_step.product_ids / show_page_step.bumps (optional, both page types): Append products to the page's checkout step as main products or as order bumps. Both are additive; bumps also promotes a product already attached to the step into a bump, which is how an existing attachment becomes one. Each bumps entry is {product_id, preheadline}, where preheadline is the optional copy shown above that bump's offer. Requires the page to be part of a funnel (400 otherwise).

markup (internal pages only): Replaces the page's entire tree. PML covers only a subset of what the ClickFunnels page editor can build, so if this page could have been created or edited in the editor, stop and get explicit approval from the user first: see the approval guardrail.
