# Notifications

Webhooks allow you to get updates in real-time about the status of your faxes. Webhooks are triggered by events such as the completion of a fax, and transmit information about the state of that fax to you via HTTP(S) or email.
HTTP webhooks are multipart/form-data POST requests, and should be processed like form submissions.



## Incoming fax event

 - [POST incomingFax](https://developers.sinch.com/docs/fax/api-reference/fax/faxes/incomingfaxevent.md): This webhook is triggered when a fax is received on a Sinch number associated with a service. The webhook will contain information about the fax, such as the sender, the recipient, and the content of the fax. You set the callback URL for incoming fax events on the service, either through the dashboard or using the service API.

### Example payloads

Multipart/form-data request payloads are encoded as forms with a content type of JSON and the actual fax content as a 'file' application/pdf attachment.

Application/json request payloads are a JSON object with the file encoded as a base64 string as part of the JSON object.

## Fax completed

 - [POST faxCompleted](https://developers.sinch.com/docs/fax/api-reference/fax/faxes/faxcompletedcallback.md): Triggered when the fax has been completed. The callback will contain information about the fax, such as the sender, the recipient, and the content of the fax. You must set the callback URL where you want the callback sent when you make a send fax request.
