# Configuring Custom Email Provider
> Send user email messages through your server.
OwnID allows you to use your servers to integrate with your own email provider so you can more completely manage, monitor, and troubleshoot your email communications.
## Build Server-Side Endpoint
This endpoint handles a request to send an OTP to a specific email address using your own email provider integration.
Implement this endpoint according to the specifications:
### Handle Requests
**Headers**
You might notice two values in request headers from the OwnID plaform:
* `ownid-signature`
* `ownid-timestamp`
These are part of securing your integration.
To help ensure the integration and endpoints are secure, you must validate the signature of the requests as described in our [security page](/building-blocks/security).
**Adding Custom HTTP Headers**
OwnID supports sending custom HTTP headers to the OTP endpoint for improved integration with your email provider. See the `Console Configuration` section above for detailed instructions.
**Payload**
OwnID will make requests to this endpoint with the following payload:
* `email` - delivery email address of the user.
* `subject` - email subject according to what is defined in the email templates.
* `body` - email body in HTML format, according to what is defined in the email templates. Includes the OTP.
```json payload example theme={null}
{
"email": "user@example.com",
"subject": "Login Verification",
"body": "Your verification code is: 5928"
}
```
### Implement Responses
Implement these responses for your endpoint:
| Status | Description | Return |
| ------ | ---------------------------- | ----------------- |
| `202` | Accepted | return empty body |
| `401` | Invalid Signature Validation | return empty body |
