Managing Video Rooms with APIs

In our guide to Creating a Video Room, we explained how to create and customize video rooms in your SignalWire Space. If you prefer to create and manage your video rooms programmatically, you can use SignalWire's REST APIs. API calls require a few pieces of authorization information found in your SignalWire Space: your project ID, Space URL, and an API token which gives access to SignalWire APIs.

A screenshot of the APIs page of a SignalWire Space. The page shows the active Project ID and Space URL, as well as a list of API tokens organized by Name, Token, and Last Used.

In the API section of your SignalWire Space, you will find your project ID, Space URL, and active API tokens. If you do not have any tokens listed, you can generate a new token and specify scopes.

Your API token should have at least the video scope enabled for all of the API calls we will discuss below. Keep in mind that this token can, for example, delete any room, mute or unmute any participant, and so on without limitations. Therefore, you may only use the API token in your server to communicate with SignalWire. It should never be exposed by making an API call from the browser. All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail. With your authorization information, you can manage all of the video room settings with our APIs that you did from your SignalWire Space.

Create a Video Room

First, we can use the API to create a video room which includes a user interface. We will need to pass our authentication information and room settings. The example below has a small selection of room settings, but you can see all of the possible parameters at the link above.

curl "https://$SPACE_URL/api/video/conferences" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
--data-raw '{
"name": "my_room",
"display_name": "My Conference Room",
"size": "medium",
"quality": "1080p",
"layout": "grid-responsive",
"enable_room_previews": true,
"enable_chat": true

This API call will return an object with the Video Room's settings and its ID. You may choose to store this ID because it is required to make other Video Room management calls we will see later.

Just like in your Dashboard, you can also create a video room without a UI via the API if you would like to start from scratch.

Video Room token

Next, we will need a Video Room token which allows a client to join the room we created. When we created our video room above, two tokens were automatically generated: a moderator token and a guest token. We will need the the Video Room ID we noted earlier to list the tokens and their permissions. If you did not store the room's ID when it was created, find it by listing your video conferences, finding the room name in the returned objects, and reading its id property.

curl "https://$SPACE_URL/api/video/conferences/$ROOM_ID/conference_tokens" \
-X GET \
-H "Accept: application/json" \

The response array includes an ID for each token, the token name (moderator or guest), their permissions, and the token string itself. We can use this "token" value with the Video Conference AppKit or the Community React library to join a fully functional Video Room.

The moderator token includes Video permissions to affect the room and any member. The guest token includes permissions which allow the token holder to control just their own audio and video settings without affecting the room settings or other members. These are listed under default permissions in the permissions reference linked above where you can see full descriptions of all Video permissions.

If you are using a Video Room without a prebuilt UI, you will need to generate a Video Room token with a separate API call. Using your own auth system, you can generate tokens with different permissions for participants depending on their desired role similarly to the different tokens generated for rooms that come with a UI. For example, a moderator might get both room permissions to affect the room and room.member permissions to affect any participant. See the Permissions reference for a full list of possible permissions.

Update room settings

You can update the settings of an existing room with a PUT call to the specified room's endpoint. This call will require the ID of the room and the parameters you would like to update. If you did not store the room's ID when it was created, find it by listing your video conferences, finding the room name in the returned objects, and reading its id property. Now, let's update the Video Room we created above to disable the Chat feature, change the name, and customize the room's dark mode colors.

curl "https://$SPACE_URL/api/video/conferences/$ROOM_ID" \
-X PUT \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
--data-raw '{
"name": "our_room",
"display_name": "Our Room'\''s Name",
"enable_chat": false,
"dark_background": "#5BB9A9",
"dark_negative": "#2E26A1"

Any room parameters we did not include in the update call will retain the settings we used when creating the room.

If you created a video room without a UI, you can update its settings with PUT /rooms/:id. This follows the same pattern as the example above.

Delete a Video Room

Finally, you can also delete the Video Room with an API call. This call only requires the room's ID. As with other calls discussed above, if you did not store the room's ID when you created it, you can find it by listing your video conferences, finding the room name in the returned objects, and reading its id property.

curl "https://$SPACE_URL/api/video/conferences/$ROOM_ID" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \

If you created a Video Room without a prebuilt UI, you can delete it using DELETE /rooms/:id.

Wrap Up

We have demonstrated the basic calls to create and manage Video Rooms with SignalWire's REST APIs. While it is easy to manage and use Video Rooms from your SignalWire Space, you are now able to do the same functions programmatically if required or preferred.
