summary: Seed MUC configuration from JSON REST API

---

# Introduction

This module fetches configuration for MUC rooms from an API when rooms

are created.

# Requirements

Should work with Prosody 0.11.

# Configuration

`muc_create_api_url`

:   URL template for the API endpoint to get settings. `{room.jid}` is

    replaced by the address of the room in question.

`muc_create_api_auth`

:   The value of the Authorization header to authenticate against the

    API. E.g. `"Bearer /rXU4tkQTYQMgdHfMLH6"`{.lua}

## Example

``` {.lua}

Component "channels.example.net" "muc"

modules_enabled = { "muc_http_defaults" }

muc_create_api_url = "https://api.example.net/muc/config?jid={room.jid}"

```

# API

A RESTful JSON API is used. Any error causes the room to be destroyed.

The returned JSON consists of two main parts, the room configuration and

the affiliations (member list).

## Schema

Here's a JSON Schema in YAML format describing the expected JSON

response data:

``` {.yaml}

type: object

properties:

  config:

    type: object

    properties:

      name: string

      description: string

      public: boolean

      allow_member_invites: boolean

      public_jids: boolean

        - affiliation

        properties:

          jid:

            type: string

            pattern: ^[^@/]+@[^/]+$

          affiliation:

            ref: '#/definitions/affiliation'

          nick: string

    - type: object

      patternProperties:

        ^[^@/]+@[^/]+$: '#/definitions/affiliation'

definitions:

  affiliation:

    type: string

    enum:

    - owner

    - admin

    - member

    - none

    - outcast

...

```

## Example

A basic example with some config settings and a few affiliations:

``` {.json}

GET /muc/config?jid=place@channels.example.net

Accept: application/json

HTTP/1.1 200 OK

Content-Type: application/json

{

   "affiliations" : [

      {

         "affiliation" : "owner",

         "jid" : "bosmang@example.net",

         "nick" : "bosmang"

      },

      {

         "affiliation" : "admin",

         "jid" : "xo@example.net",

         "nick" : "xo"

      },

      {

         "affiliation" : "member",

         "jid" : "john@example.net"

      }

   ],

   "config" : {

      "archiving" : true,

      "description" : "This is the place",

      "members_only" : true,

      "moderated" : false,

      "name" : "The Place",

      "persistent" : true,

      "public" : false,

      "subject" : "Discussions regarding The Place"

   }

}

```

To allow the creation without making any changes, letting whoever

created it be the owner, just return an empty JSON object:

    HTTP/1.1 200 OK

    Content-Type: application/json

    {}
