metaobjectDefinitionUpdate

mutation

Requires write_metaobject_definitions access scope.

Updates a MetaobjectDefinition's configuration and field structure. You can modify the definition's name, description, display name key, access controls, and capabilities, as well as those of all its fields.

The mutation supports reordering fields when resetFieldOrder is true, which arranges submitted fields first followed by alphabetized omitted fields.

Update ordering of fields on an existing metaobject definition

Description

To update the ordering of fields on an existing metaobject definition, use the `metaobjectDefinitionUpdate` mutation with the `resetFieldOrder` boolean. The following example shows updating the ordering of the fields on the "Color" metaobject definition. Prior to the update, the ordering of the fields is "name", "hex", "accent_color". After the update, the ordering changes to "hex", "name", and "accent_color".

mutation UpdateMetaobjectDefinition($id: ID!, $definition: MetaobjectDefinitionUpdateInput!) {
  metaobjectDefinitionUpdate(id: $id, definition: $definition) {
    metaobjectDefinition {
