# Introduction
`SND` is a command introduced with [MSNP2](../versions/msnp2.md).

It is a Notification Server command, without either a request or response payload.

Sends a service invitation to an e-mail address or directory user.
For the version of this command that supports friendly names that superseded this command, read [SDC](sdc.md).

# Client/Request
`SND TrID target-address {translation-lcid} {requesting-library} {client-identification}`

Where `target-address` is the E-mail address or index from the last [FND](fnd.md) response you'd like to invite to the service.

Where `translation-lcid` is the LCID of the translation you'd like the invitation to be in.
Added since [MSNP3](../versions/msnp3.md).

Where `requesting-library` is the name of the library that requested this CVR, usually `MSMSGS` or `MSNMSGR`.
Added since [MSNP3](../versions/msnp3.md).

Where `client-identification` is the internal name of the codebase used to create `requesting-library`, usually `MSMSGS`.
Added since [MSNP4](../versions/msnp4.md).

# Server/Response

Where `OK` is always `OK`.
