1. Authentication
First, you access the Figma application, select the App management menu then select the Credential tab:
Next, you enter the Username and select the corresponding permission group (here you group the Sigma Livestream Full permission ):
After you select Submit , the Sigma system will generate a Username and Secret Key . You need to save this password or download the credential file by selecting Download as .env file .
After having Username and Secret Key , you use Base64Encode tool to create token for Authorization header with the following syntax:
Copy Authorization: Basic Base64Encode ( < Username > : < Secret Key > ) Finally, you get App ID information by selecting the App management menu, selecting the General tab , then you can see App ID information as shown below.
2. API Create live transcode channel
To create a live transcode channel with the following settings:
Available in 03 profiles 1080p, 720p, 480p
Catchup live session saved to S3 storage (Note: re-enter channel name and S3 configuration)
You can use the following API:
Copy curl --location 'https://api.sigma.video/api/livestream/channels' \
--header 'X-App-Id: <app_id>' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic <token>' \
--data '{
"name": "<channel_name>",
"description": null,
"tags": [],
"transcodeProfile": [
"fbffbd08-ed7f-4a51-aabd-3132ac863bb5",

],

}
}
}' If the API call is successful, the HTTP Response code will be 201 , along with the response body being a json object in which the most important information is the id of the newly created channel as in the example below. This ID is used in the APIs to start/stop live sessions or delete channels.
Copy {
"id" : "42efeee4-e94e-4444-b0a6-90850413519d" ,
"name" : "Channel_02" ,
"description" : null,
…
} 3. Get information of a channel
After creating a channel, you can get the details of a channel by calling the following API:
Copy curl --location 'https://api.sigma.video/api/livestream/channels/<channel_id>' \
--header 'X-App-Id: <app_id>' \
--header 'Authorization: Basic <token>' If the API call is successful, the HTTP Response code will be 200 . It contains some important information such as:
currentSessionId: if the channel is in a livestream session, we will receive the session id.
For channels with catchup for VOD configured to be saved to S3, the endpoint to access the master.m3u8 file will look like this:<s3>/sigma-livestream/<session_id>/catchup/master-catchup.m3u8
rtmpServer: rtmp url to push stream.
liveStreamUrl: URL to watch live.
The received data will be as follows:b
