< p > The API to send notices is as follows:< / p >
< pre > < code > POST /_synapse/admin/v1/send_server_notice
< / code > < / pre >
< p > or:< / p >
< pre > < code > PUT /_synapse/admin/v1/send_server_notice/{txnId}
< / code > < / pre >
< p > You will need to authenticate with an access token for an admin user.< / p >
< p > When using the < code > PUT< / code > form, retransmissions with the same transaction ID will be
ignored in the same way as with < code > PUT /_matrix/client/r0/rooms/{roomId}/send/{eventType}/{txnId}< / code > .< / p >
< p > The request body should look something like the following:< / p >
< pre > < code class = "language-json" > {
" user_id" : " @target_user:server_name" ,
" content" : {
" msgtype" : " m.text" ,
" body" : " This is my message"
}
}
< / code > < / pre >
< p > You can optionally include the following additional parameters:< / p >
< ul >
< li > < code > type< / code > : the type of event. Defaults to < code > m.room.message< / code > .< / li >
< li > < code > state_key< / code > : Setting this will result in a state event being sent.< / li >
< / ul >
< p > Once the notice has been sent, the API will return the following response:< / p >
< pre > < code class = "language-json" > {
" event_id" : " < event_id> "
}
< / code > < / pre >
< p > Note that server notices must be enabled in < code > homeserver.yaml< / code > before this API
can be used. See < a href = "../server_notices.html" > the server notices documentation< / a > for more information.< / p >
