h1. Deliver delivery receipt

Upon receiving a delivery receipt from a supplier from a network, Smartswitch will send HTTP query to a URL of a client.
The URL of a client should be specified in menu _Originator -> Technologies -> HTTP -> Delivery receipt -> URL_.

By default HTTP query will be sent using POST method.
The body of a POST query will contain following attributes:

|*attribute*|*description*|
|message_id|ID of a message.
Coincides with an "id" attribute, which has been returned to a client in response to HTTP API [[HTTP API message|message]] invocation by a client| 
|message_state|the state of a message.
Must be one of: enroute, delivered, expired, undeliverable, accepted, unknown, rejected|

In case if client requests sending attributes in some other format, for example JSON, you can change format on the side of Smartswitch.
To do this, you should fill tab _Originator -> Technologies -> HTTP -> Delivery receipt_ according to demands of a client.
