JMAP API

The MtaStageMail singleton is available via the urn:stalwart:jmap capability.

x:MtaStageMail/get

This is a standard Foo/get method as defined in RFC 8620, Section 5.1.

For singletons, the ids argument should be the literal singleton (or null to return the single instance).

This method requires the sysMtaStageMailGet permission.

curl -X POST https://mail.example.com/api \
  -H 'Authorization: Bearer $TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{
      "methodCalls": [
        [
          "x:MtaStageMail/get",
          {
            "ids": [
              "singleton"
            ]
          },
          "c1"
        ]
      ],
      "using": [

      ]
    }'

x:MtaStageMail/set

This is a standard Foo/set method as defined in RFC 8620, Section 5.3.

For singletons, only the update argument with id singleton is accepted; create and destroy arguments are rejected.

This method requires the sysMtaStageMailUpdate permission.

  -H 'Authorization: Bearer $TOKEN' \
  -H 'Content-Type: application/json' \
