# Overview

> Review, approve, and reject Sender ID registrations for your network via API.

## Operator API

The Operator API gives mobile network operators (MNOs) programmatic access to manage Sender ID registrations submitted for their network. This is the API equivalent of the [Senderz Operator Console](https://senderz.ai/operators).

Use it to:

* **Review** incoming SID registration requests from brands, aggregators, and CPaaS providers
* **Approve, reject, or request more information** on registrations with structured reasons
* **Monitor** registration volumes, approval rates, and processing times across your network

## Who uses this API

MNOs and their integration teams. Each operator receives an API key scoped with `operator:read` and `operator:write` permissions. The key is bound to the operator's network, so all responses are automatically filtered to registrations relevant to that operator.

## Registration lifecycle (operator view)

```
pending_operator_review → approved → registered (on market register)
                        └→ info_requested → resubmitted → pending_operator_review
                        └→ rejected
```
