1 # Introduction
2
3 This module externalizes MUC authorization via HTTP.
4 Whenever a user wants to join a MUC, an HTTP GET request is made to `authorization_url`
5 with the user bare jid (`userJID`) and the MUC jid (`mucJID`) as GET parameters.
6 Example:
7 `https://www.prosody.im/users/can-join/?userJID=romeo@example.com&mucJID=teaparty@chat.example.com`
8
9 This allows an external service to decide whether a user is authorized to join a MUC or not.
10
11 When a user is authorized to join a MUC, this module expects the following JSON payload:
12 ```
13 {
14 allowed: true,
15 error: "",
16 }
17 ```
18 Otherwise, either the user not being authorized or some failure in the external service:
19 ```
20 {
21 allowed: false,
22 error: "Some error message to be displayed in this module's logs",
23 }
24 ```

50 This module can be enabled/disabled for specific rooms. Only one of the following settings must be set.
51 ```
52 -- muc_http_auth_enabled_for = {"teaparty"}
53 -- muc_http_auth_disabled_for = {"teaparty"}
54 ```
55 If none or both are found, all rooms in the MUC component will have this module enabled.
