API Overview

The following denotes the HTTPS-based API for BrowserStack. It provides browser-as-a-service for automated cross-browser testing. The goal is to provide a simple service which can easily be used by any browser testing framework.

Authentication

All methods need to authenticate who you are, before spawning browser workers and deleting a worker for example. Authentication is done using your username and the BrowserStack access key within the HTTP request.

For example:

curl -u "username:access_key" https://api.browserstack.com/5

Note: A 401 Unauthorized response is received if an unauthorized request is made.

Schema

All requests are made to https://api.browserstack.com/VERSION/ and all returned data is done so in JSON-format. This documentation outlines version 5.

curl -i -u "username:access_key" https://api.browserstack.com/5

Response:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf8
Status: 200 OK
X-API-Version: 5

{}

All date formats are given in ISO-8601 which can be processed natively with Date.parse in compatible JavaScript environments.

Error Handling

All requests are pre-processed and validated. This section outlines how we handle errors within the API and respond to them.

All API requests are validated. The following is an example output for a required parameter that wasn't given.

HTTP/1.1 422 Unprocessable Entity
Content-Length: 136

{
  "message": "Validation Failed",
  "errors": [
    {
      "field": "type",
      "code": "required"
    }
  ]
}

Possible error codes are required and invalid.

HTTP Verbs

The API is kept concise and simple by making use of relevant HTTP verbs on each request. The specifications for these are vague and their use within this API is specific but in general, we follow the following rules:

HEAD - Performs the request to assess the status of a resource and expects no content response.
GET - Used to retrieve resources.
POST - Used to create new resources.
PUT - Used to update resources.
DELETE - Used to delete resources.

          },
          {
            "browser": "edge",
            "browser_version": "insider preview"
          }...
        ],
    },

          }...
        ],
      }...
    },
}

A flat parameter can also be passed to get browsers in a flat structure

GET /browsers?flat=true

For example:

curl -u "username:access_key" https://api.browserstack.com/5/browsers?flat=true

Output:

[  
  {
    "os": "Windows",
    "os_version": "10",
    "browser": "chrome",
    "device": null,
    "browser_version": "84.0",
    "real_mobile": null
  },
  {
    "os": "Windows",
    "os_version": "10",
    "browser": "edge",
    "device": null,
    "browser_version": "85.0 beta",
    "real_mobile": null
  },
  {
    "os": "OS X",
    "os_version": "Catalina",
    "browser": "firefox",
    "device": null,
    "browser_version": "79.0",
    "real_mobile": null
  },
  {
    "os": "OS X",
    "os_version": "Catalina",
    "browser": "firefox",
    "device": null,
    "browser_version": "80.0 beta",
    "real_mobile": null
  }....
]

Create a New Browser Worker

A browser worker is simply a new browser instance. A user can start multiple browser worker at a time. All browser workers when created are pushed in a queue and they run when their turn comes. We make sure that your browser worker starts running as soon as possible. Your testing time is calculated from the time when browser worker starts running.

POST /worker

Note: This call requires authentication. A 401 Unauthorized response is given if an unauthorized request is made.

For example:

curl -u "username:access_key" -X POST -d '{"os":"OS X","os_version":"Mojave","url":"https://browserstack.com","browser":"chrome","browser_version":"75.0"}' https://api.browserstack.com/5/worker -H 'content-type: application/json'

Response:

{"id":123456789,"url":"https://browserstack.com"}

Once a worker has been spawned you can then control this browser instance remotely. You can also look at the testing session status at the Automate Dashboard. This will provide you with the general details about the session and a live preview of the remote machine.

HTTP/1.1 200 Success
Content-Type: application/json
X-API-Version: 5

{
  "id": "123456789"
}

Screenshots

Use this method to take a screenshot at the current state of the worker.

GET /worker/<id>/screenshot(.format)

Acceptable formats are json, xml and png. This information can also be provided via the HTTP Accept headers: text/json, text/xml, image/png respectively.

For example:

curl -u "username:access_key" https://api.browserstack.com/5/worker/123456789/screenshot.json

Get Details of all Browser Workers

Returns comprehensive information, such as, worker ID, browser URL, session ID, etc., for all the browser workers you've created. It also returns the current status of the workers, which can be either queue or running.

GET /workers

Example request:

curl -u "username:access_key" -X GET https://api.browserstack.com/5/workers

Example response:

[
  {
   "id": "<workerId>",
   "status": "running",
   "os": "OS X",
   "os_version": "Mojave",
   "browser": "chrome",
   "browser_version": "75.0",
   "real_mobile": null,
   "device": null,
   "browser_url": "<dashboard_url_of_the_session>",
   "sessionId": "<sessionId>"
  },
 {
    "id": "<workerId>",
    "status": "queue",
    "os": "android",
    "os_version": "2.2",
    "device": "Samsung Galaxy S",
    "browser": "Android Browser",
    "browser_version": null,
    "real_mobile": false,
    "browser_url": "<dashboard_url_of_the_session>",
    "sessionId": "<sessionId>"
  } ...]

Terminating a Browser Worker

Use this method to terminate a worker. Useful if you set the worker up to run indefinitely or if you've received all the information needed and you want to save on credit time.

DELETE  /worker/<id>

The id is the id returned when you first created the worker. Once called the browser instance will be immediately terminated and will no longer be accessible.

Note: This call requires authentication. If the request was made unauthorized a 401 Unauthorized response is given. Alternatively, if the authorized user is not the owner of the worker or id does not exist a 403 Forbidden response is given. Also, if this request is sent within 60 seconds of starting the worker, the response will be 422 Unprocessable Entity and the worker will be terminated after 60 seconds of its running time.

For example:

curl -u "username:access_key" -X DELETE https://api.browserstack.com/5/worker/123456789

Getting Worker Status

Sometimes you will need to check on the status of a worker. Not to be confused with the state of the javascript environment within the worker, this method simply determines whether the worker is in the queue, running or terminated.

GET /worker/<id>

This call requires authentication. If the request was made unauthorized a 401 Unauthorized response is given. Alternatively, if the authorized user is not the owner of the worker a 403 Forbidden response is given.

For example:

curl -u "username:access_key" https://api.browserstack.com/5/worker/123456789

If the worker has been terminated an empty response is given. Otherwise, you get a response with status and browser details.

{
  status: 'running',
  browser: 'ie',
  browser_version: '6.0',
  os: 'Windows',
  os_version: 'XP',
  sessionId: "<sessionId>",
  browser_url: "<dashboard url for the session>"
}

If you want to know the list of your current workers with their status, use the following method.

GET /workers

This method will return the list of workers whose status is either queue or running.

For example:

curl -u "username:access_key" https://api.browserstack.com/5/workers

Response:

[
  {
    status: 'running',
    browser: 'ie',
    version: '6.0',
    os: 'Windows',
    os_version: 'XP',
    sessionId: "<sessionId>",
    browser_url: "<dashboard url for the session>"
  },
  {
    status: 'queue',
    device: 'Samsung Galaxy Tab 8.9',
    os: 'android',
    os_version: '2.2',
    sessionId: "<sessionId>",
    browser_url: "<dashboard url for the session>"
  } ...
]

Getting API Status

If you want to know the status of your API, use the following method

GET /status

This will return the current status of API, like how much API time has been used and how many workers are running parallelly. All the paid plans have no time limits, only limit on parallel workers you can create.

For example:

curl -u "username:access_key" https://api.browserstack.com/5/status

  {
    used_time: 4235.4,
    total_available_time: 6000,
    running_sessions: 1,
    sessions_limit: 1
  }

The time returned is in seconds.

If a user runs out of API time, all requests will return the following response

{
  message: "You have run out of API time"
}

Note: You can make up to 1600 API requests every 5 minutes.
