Solicitudes de Firma

Crear y Enviar Solicitud de Firma (Atómico)

Crea y envía inmediatamente una solicitud de firma en una única operación atómica. Este endpoint combina la funcionalidad de POST /signing-requests y POST /signing-requests//send.

Beneficios Clave:

Una sola llamada a la API en lugar de dos solicitudes separadas
Valida todos los requisitos de envío ANTES de crear la solicitud de firma
Deducción de créditos atómica: solo cobra si todo tiene éxito
Devuelve status: ‘sent’ inmediatamente con los detalles del primer firmante
Más eficiente (ahorra 1 llamada a la API + tiempo de ida y vuelta)

Validación:

Todas las validaciones de creación estándar (document/template, recipients, fields)
Validaciones de envío adicionales:
- Todos los firmantes deben tener first_name y un email válido
- Los campos de solo lectura requeridos deben tener final_value completado
- Los campos de datos prellenados (variable_name) deben tener los datos de usuario correspondientes
- La empresa debe tener créditos suficientes (≥1)

Atomicidad:

Si alguna validación falla, no se crea nada
El crédito solo se deduce después de una creación exitosa y antes del envío del email
Si el envío del email falla después de la creación, la solicitud de firma permanece en estado ‘draft’ y el crédito NO se deduce

Patrón de ID Temporal: Para la creación basada en documento, usa IDs temporales (formato: ‘temp_X’) para referenciar destinatarios antes de la creación. La API valida todas las referencias y mapea automáticamente los IDs temporales a UUID reales.

Límite de Tasa: 120 solicitudes/minuto (igual que las operaciones de escritura)
