2026.7.1.0 API Release Notes

Update: Custom Fields API

Added support for PATCH in the Custom Field public API endpoint:

• Endpoint: /integration/v2/custom_field/{id}/
• New capability: Partially update existing custom field metadata without recreating the field.

This update enables integrations to update custom field definitions in place, reducing operational overhead and eliminating the need to delete/recreate fields for metadata-only changes.

You can now update the following fields:

• name_singular
• name_plural
• options
• tooltip_text
• backref_name
• backref_tooltip_text

Validation and behavior

• PATCH requests enforce field-type-specific validation (for example, picker and object-set constraints).
• Immutable properties are protected; attempts to modify them are ignored:
  • field_type
  • allow_multiple
  • allowed_otypes
  • builtin_name
