## Authentication

La mayoría de las APIs de Sequence requieren autenticación usando ya sea:

* **Project Access Key**: Para solicitudes del lado del cliente, estas se listan como `public`.
* **Service Token**: Para solicitudes del lado del servidor que requieren permisos elevados, estas requieren pasar un token secreto bearer y se listan como `secret`.

Puede generar estas credenciales en el panel de [Sequence Builder](https://sequence.build).

## Límites de uso (Rate Limits)

Los límites de uso de la API varían según el nivel y los MAUs disponibles. Revise la configuración de su proyecto en el panel de Sequence Builder para ver sus límites específicos.
