the wizards.
Gravity Forms tutorials, real-world builds, and the latest from Gravity Wiz.
gpacl_runtime_entry_meta_keys
Filter the entry meta keys treated as “runtime” — updated during submission.
gcoai_deprecated_image_models
Filter the image models OpenAI is shutting down, keyed by shutdown date in `Y-m-d` format. A model listed here is hidden from the Image field’s model list unless already selected, labelled as deprecated when shown, and warned about in the form editor.
gcoai_image_models
Filter the models offered by the OpenAI Image field. A model added here is listed in the form editor and behaves as a member of the `gpt-image-` family if it is named like one. Set `background` to true to offer the Transparent Background setting for it. New fields start on the first model listed that is not deprecated.
gpb_cancellation_reason_mode
Filters whether customers are asked for a reason when cancelling a booking.
gpb_booking_operation_restrictions
Filter the restrictions that apply to a booking operation. Return null to allow the operation, or an array with a `type` key (and, for deadline restrictions, a `deadline` key) to restrict it. This is the single source of truth for whether an operation is permitted, so it can be used to relax or tighten the default rules.
gpb_notify_on_ics_account_removed
Filter whether to notify when syncing stops because a config’s connected Google account was removed from GCGC.
spellbook_support_chat_enabled
Filter whether the support chat widget is enabled on the Spellbook admin page.
gpi_scope_field_options
Filter the options available in a scope’s drop down on the Inventory page. Useful when a scope field’s values are populated programmatically (e.g. a Hidden field) and the desired options can be neither derived from the field’s choices nor found in previously submitted entries.
gcoai_request_headers
Filter the headers for requests sent to the OpenAI API.
gpi_field_inventory
Filter a field’s available inventory. Fields without inventory tracking enabled are passed as null; return an integer to provide their inventory.
gfcb_localized_script_data
Filter the localized script data refreshed in the Cache Buster’s AJAX response. Unset a handle to leave its data alone, or return an empty array to disable refreshing entirely.
gpaa_compute_routes_request
Filter the request body sent to Google’s Compute Routes endpoint.
gpaa_travel_estimate_template
Filter the template used to render a Travel Estimate field’s content. Use the {distance} and {time} tags to control the order and wording, e.g. “{time} ({distance})”. Only reference estimates that are active for the field’s Estimate Type. A tag for an inactive estimate renders empty, so surrounding literals (such as brackets) would remain.

gpb_max_duration
Filter the maximum booking duration. This can be used to change the enforced maximum for a role or other request context without changing the Service setting.
