  2. Persist Session State

The Hyperbeam profile API allows you to persist session state including bookmarks, history, passwords, and cookies which can be loaded into another session at a later time. This allows you to resume sessions without requiring the user to open up web pages or authenticate again.

​
Saving a Session

In order to save a session, the profile.save parameter must be set to true when starting a Chromium session.

​
Example Request:

curl --request POST \
     --url https://engine.hyperbeam.com/v0/vm \
     --header 'Authorization: Bearer AUTH_VALUE' \
     --header 'Content-Type: application/json' \
     --data '{
 "profile": {
  "save": true
 }
}'

After the session is created, the response object will contain a session_id property that you must save in order to load the session state again afterwards.

If you wish to save a session that was already persisted, you do not need to store the new session_id in your database. Instead, you can use the initial session’s session_id to load/save that session. Therefore, you do not need to continually update the session_id corresponding to the session.

​
Example Response:

{
  "session_id": "52f968cb-6739-4197-83d7-2305fe5d6f54",
  "embed_url": "https://vwdrccwgpv181powg61ggyvy.hyperbeam.com/Uvloy2c5QZeD1yMF_l1vVA?token=c8iw3SmQglOU0ugfLr3dWY2LalSKI_WOGUldEt8knbw",
  "admin_token": "51JOZEEcMp4trCwbpTS3jjQc0lSmeAZpPfxioDqe73U"
}

​
Loading a Session

In order to load a previous session, the profile.load parameter must be set to the session_id you would like to resume when starting a Chromium session.

​
Example Request:

curl --request POST \
     --url https://engine.hyperbeam.com/v0/vm \
     --header 'Authorization: Bearer AUTH_VALUE' \
     --header 'Content-Type: application/json' \
     --data '{
 "profile": {
  "load": <session_id>
 }
}'

How Do We Persist Sessions?

When profile.save is set to true, we encrypt and store the Chrome profile of the session in Amazon S3.

This Chrome profile is associated with the session_id that was returned to you on session creation.

When profile.load is set to a session ID, we look for a stored Chrome profile that corresponds to that session_id, and decrypt and load the Chrome profile if there is a match.

This results in bookmarks, history, cookies, and passwords being persisted.
