# Contract Integration

If the policyholder is a smart contract, the contract must implement certain functions to interact with an insurance contract for the purposes of issuing, redeeming, and submitting claims for policies.

### onPolicyIssued

```solidity
function onPolicyIssued(address operator, address from, string policyId) external returns (bytes4)
```

This function will called by the insurance contract (policy manager facet) when the policy is issued and the caller is contract.

*The selector can be obtained in Solidity with `IInsuranceIssuer.onPolicyIssued.selector`.*

| Name     | Type    | Description           |
| -------- | ------- | --------------------- |
| operator | address | The operator address. |
| from     | address | The from address.     |
| policyId | string  | The policy id.        |

| Name | Type   | Description                                            |
| ---- | ------ | ------------------------------------------------------ |
| \[0] | bytes4 | The bytes4 of the selector of onPolicyIssued function. |

### onPolicyRedeemed

```solidity
function onPolicyRedeemed(address operator, address from, string policyId) external returns (bytes4)
```

This function will called by the insurance contract (policy manager facet) when the policy is redeemed and the caller is contract.

*The selector can be obtained in Solidity with `IInsuranceIssuer.onPolicyRedeemed.selector`.*

| Name     | Type    | Description           |
| -------- | ------- | --------------------- |
| operator | address | The operator address. |
| from     | address | The caller address.   |
| policyId | string  | The policy id.        |

| Name | Type   | Description                                              |
| ---- | ------ | -------------------------------------------------------- |
| \[0] | bytes4 | The bytes4 of the selector of onPolicyRedeemed function. |

### onClaimSubmitted

```solidity
function onClaimSubmitted(address operator, address from, string policyId) external returns (bytes4)
```

This function will called by the insurance contract (claim manager facet) when the policy is submitted and the caller is contract.

*The selector can be obtained in Solidity with `IInsuranceIssuer.onClaimSubmitted.selector`.*

| Name     | Type    | Description           |
| -------- | ------- | --------------------- |
| operator | address | The operator address. |
| from     | address | The caller address.   |
| policyId | string  | The policy id.        |

| Name | Type   | Description                                              |
| ---- | ------ | -------------------------------------------------------- |
| \[0] | bytes4 | The bytes4 of the selector of onClaimSubmitted function. |
