# Forms

[Forms](/api-reference/forms/forms.md) define configurable questionnaires and contain translated [FormFields](/api-reference/forms/form-fields.md). Field behavior comes from [FormFieldTypes](/api-reference/forms/form-field-types.md), while [DefaultValueSources](/api-reference/forms/default-value-sources.md), [FormFieldValidations](/api-reference/forms/form-field-validations.md), [FormFieldValidationTypes](/api-reference/forms/form-field-validation-types.md), and [FormFieldDisplayConditions](/api-reference/forms/form-field-display-conditions.md) control prefilling, validation, and conditional visibility.

Submitted forms create [FormMessages](/api-reference/forms/form-messages.md) and corresponding [FormMessageFields](/api-reference/forms/form-message-fields.md). When receipt or approval is required, [FormMessageConfirmations](/api-reference/forms/form-message-confirmations.md) expose the token-based confirmation workflow.

Forms use [Entity Permissions](/introduction/resource-capabilities/entity-permissions.md) for access, [Translations](/introduction/resource-capabilities/translations.md) for localized content, and [URL Context](/introduction/resource-capabilities/url-context.md) for stable links.
