STF API

Overview

STF API is a RESTful API which allows you to reserve and release any STF device. Internally STF uses Swagger interface for its API implementation. For those who don't know about Swagger, Swagger provides specifications for RESTful apis. By using it you can generate documentation and client SDKs in various language automatically for Swagger-enabled apps. This gives you power to use STF APIs in any language of your favorite. You can read more about Swagger here.

Swagger documentation

Swagger documentation for the API is available here.

APIs

A few examples are also provided. We also have a more advanced example showing how to use the API with Appium.

Authentication

STF uses OAuth 2.0 for authentication. In order to use the API, you will first need to generate an access token. Access tokens can be easily generated from the STF UI. Just go to the Settings tab and generate a new access token in Keys section. Don't forget to save this token somewhere, you will not be able to see it again.

The access token must be included in every request.

Using cURL:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user

Using Node.js:

var Swagger = require('swagger-client');

var SWAGGER_URL = 'https://stf.example.org/api/v1/swagger.json';
var AUTH_TOKEN  = 'xx-xxxx-xx';

// Without Promise
var client = new Swagger({
  url: SWAGGER_URL
, authorizations: {
    accessTokenAuth: new Swagger.ApiKeyAuthorization('Authorization', 'Bearer ' + AUTH_TOKEN, 'header')
  }
, success: function() {
    client.user.getUser(function(user) {
      console.log(user.obj)
    })
 }
});

// Using Promise
var clientWithPromise = new Swagger({
  url: SWAGGER_URL
, usePromise: true
, authorizations: {
    accessTokenAuth: new Swagger.ApiKeyAuthorization('Authorization', 'Bearer ' + AUTH_TOKEN, 'header')
  }
})

clientWithPromise.then(function(api) {
  api.user.getUser()
    .then(function(res) {
      console.log(res.obj.user.email)
      // vishal@example.com
    })
})

Pretty printing output

Please use jq for pretty printing. It's very easy to use:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/devices | jq .

It also provides much more complex patterns for retrieving and/or filtering data.

Devices

GET /devices

List all STF devices (including disconnected or otherwise inaccessible devices).

GET /api/v1/devices

Using cURL:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/devices

Using Node.js:

clientWithPromise.then(function(api) {
  api.devices.getDevices()
    .then(function(res) {
      console.log(res.obj.devices.length)
      // 50
    })
})

// OR
clientWithPromise.then(function(api) {
  api.devices.getDevices({fields: 'serial,using,ready'})
    .then(function(res) {
      console.log(res.obj.devices)
      // [ { serial: 'xxxx', using: false, ready: true },
      //   { serial: 'yyyy', using: false, ready: true }]
    })
})

GET /devices/{serial}

Returns information about a specific device.

GET /api/v1/devices/{serial}

Using cURL:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/devices/xxxxxxxxx

Using Node.js:

clientWithPromise.then(function(api) {
  api.devices.getDeviceBySerial({serial: 'xxxx'})
    .then(function(res) {
      console.log(res.obj.device.serial)
      // xxxx
    })
})

// OR
clientWithPromise.then(function(api) {
  api.devices.getDeviceBySerial({serial: 'xxxx', fields: 'serial,using,ready'})
    .then(function(res) {
      console.log(res.obj.device)
      // { serial: 'xxxx', using: false, ready: true }
    })
})

User

GET /user

Returns information about yourself (the authenticated user).

GET /api/v1/user

Using cURL:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user

Using Node.js:

clientWithPromise.then(function(api) {
  api.user.getUser()
    .then(function(res) {
      console.log(res.obj.user.email)
      // vishal@example.com
    })
})

GET /user/devices

Returns a list of devices currently being used by the authenticated user.

GET /api/v1/user/devices

Using cURL:

curl -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user/devices

Using Node.js:

clientWithPromise.then(function(api) {
  api.user.getUserDevices()
    .then(function(res) {
      console.log(res.obj.devices.length)
      // 1
    })
})

// OR
clientWithPromise.then(function(api) {
  api.user.getUserDevices({fields: 'serial,using,ready'})
    .then(function(res) {
      console.log(res.obj.devices)
      // [ { serial: 'xxxx', using: true, ready: true } ]
    })
})

POST /user/devices

Attempts to add a device under the authenticated user's control. This is analogous to pressing "Use" in the UI.

POST /api/v1/user/devices

Using cURL:

curl -X POST --header "Content-Type: application/json" --data '{"serial":"EP7351U3WQ"}' -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user/devices

Using Node.js:

var device = {serial: 'yyyy', timeout: 900000 }

clientWithPromise.then(function(api) {
  return api.user.addUserDevice({device: device})
    .then(function(res) {
      console.log(res.obj)
      // { success: true, description: 'Device successfully added' }
    })
})
.catch(function(err) {
  console.log(err)
})

DELETE /user/devices/{serial}

Removes a device from the authenticated user's device list. This is analogous to pressing "Stop using" in the UI.

DELETE /api/v1/user/devices/{serial}

Using cURL:

curl -X DELETE -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user/devices/{serial}

Using Node.js:

clientWithPromise.then(function(api) {
  return api.user.deleteUserDeviceBySerial({serial: 'yyyy'})
    .then(function(res) {
      console.log(res.obj)
      // { success: true, description: 'Device successfully removed' }
    })
})
.catch(function(err) {
  console.log(err)
})

POST /user/devices/{serial}/remoteConnect

Allows you to retrieve the remote debug URL (i.e. an adb connectable address) for a device the authenticated user controls.

Note that if you haven't added your ADB key to STF yet, the device may be in unauthorized state after connecting to it for the first time. We recommend you make sure your ADB key has already been set up properly before you start using this API. You can add your ADB key from the settings page, or by connecting to a device you're actively using in the UI and responding to the dialog that appears.

POST /api/v1/user/devices/{serial}/remoteConnect

Using cURL:

curl -X POST -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user/devices/{serial}/remoteConnect

Using Node.js:

clientWithPromise.then(function(api) {
  return api.user.remoteConnectUserDeviceBySerial({serial: 'CB5125LBYM'})
    .then(function(res) {
      console.log(res.obj.remoteConnectUrl)
      // $PROVIDER_IP:16829
    })
})
.catch(function(err) {
  console.log(err)
  // {"success":false,
  //  "description":"Device is not owned by you or is not available"}' }
})

DELETE /api/v1/user/devices/{serial}/remoteConnect

Disconnect a remote debugging session.

DELETE /api/v1/user/devices/{serial}/remoteConnect

Using cURL:

curl -X DELETE -H "Authorization: Bearer YOUR-TOKEN-HERE" https://stf.example.org/api/v1/user/devices/{serial}/remoteConnect

Using Node.js:

clientWithPromise.then(function(api) {
  return api.user.remoteDisconnectUserDeviceBySerial({serial: 'CB5125LBYM'})
    .then(function(res) {
      console.log(res.obj)
      // { success: true,
    //     description: 'Device remote disconnected successfully' }
    })
})
.catch(function(err) {
  console.log(err)
  // {"success":false,"description":"Device is not owned by you or is not available"}
})

Using NodeJs

Connect to a device and retrieve its remote debug URL

// stf-connect.js

var Swagger = require('swagger-client');

var SWAGGER_URL = 'https://stf.example.org/api/v1/swagger.json';
var AUTH_TOKEN  = 'xx-xxxx-xx';

// Using Promise
var client = new Swagger({
  url: SWAGGER_URL
, usePromise: true
, authorizations: {
    accessTokenAuth: new Swagger.ApiKeyAuthorization('Authorization', 'Bearer ' + AUTH_TOKEN, 'header')
  }
})

var serial = process.argv.slice(2)[0]

client.then(function(api) {
  return api.devices.getDeviceBySerial({
    serial: serial
  , fields: 'serial,present,ready,using,owner'
  }).then(function(res) {
      // check if device can be added or not
      var device = res.obj.device
      if (!device.present || !device.ready || device.using || device.owner) {
        console.log('Device is not available')
        return
      }

      // add device to user
      return api.user.addUserDevice({
        device: {
          serial: device.serial
        , timeout: 900000
        }
      }).then(function(res) {
        if (!res.obj.success) {
          console.log('Could not add device')
          return
        }

        // get remote connect url
        return api.user.remoteConnectUserDeviceBySerial({
          serial: device.serial
        }).then(function(res) {
          console.log(res.obj.remoteConnectUrl)
        })
      })
  })
})

Disconnect a device once you no longer need it

var Swagger = require('swagger-client');

var SWAGGER_URL = 'https://stf.example.org/api/v1/swagger.json';
var AUTH_TOKEN  = 'xx-xxxx-xx';

var client = new Swagger({
  url: SWAGGER_URL
, usePromise: true
, authorizations: {
    accessTokenAuth: new Swagger.ApiKeyAuthorization('Authorization', 'Bearer ' + AUTH_TOKEN, 'header')
  }
})

var serial = process.argv.slice(2)[0]

client.then(function(api) {  
  return api.user.getUserDevices({
    serial: serial
  , fields: 'serial,present,ready,using,owner'
  }).then(function(res) {
      // check if user has that device or not
      var devices = res.obj.devices
      var hasDevice = false

      devices.forEach(function(device) {
        if(device.serial === serial) {
          hasDevice = true;
        }
      })

      if (!hasDevice) {
        console.log('You do not own that device')
        return
      }

      return api.user.deleteUserDeviceBySerial({
        serial: serial
      }).then(function(res) {
        if (!res.obj.success) {
          console.log('Could not disconnect')
          return
        }
        console.log('Device disconnected successfully!')
