susoapi

The goal of susoapi is to offer a user-friendly interface for Survey Solutions’ RESTful and GraphQL APIs. The package provide an R wrapper function for each Survey Solutions API endpoint, and in so doing enable users to execute all API actions without leaving R.

Installation

The package is not yet on CRAN, but can be installed via the following command:

# if needed, install `devtools` by uncommenting the immediately below
# install.packages("devtools")
devtools::install_github("arthur-shaw/susoapi")

Usage

Scope

To execute an API action, one simply needs to find the appropriate function for the object of interest:

  • Questionnaires
  • Assignments
  • Interviews
  • Users
  • Export

See the Reference for more details.

Authentication

But before executing an action, users should provide record their credentials for server authentication:

set_credentials(
  server = "https://example.server",
  workspace = "myworkspace",
  user = "My_API_user1",
  password = "MySecretPassword2Day"
)

This accomplishes a few simultaneous goals:

  • Records credentials for reuse later–both within and across R sessions
  • Stores credentials in a safe place–outside of code

Example commands

To get the list of questionnaires loaded on the server:

# get a dataframe of questionnaires and their attributes
all_questionnaires <- get_questionnaires()

To create users:

# create a supervisor
create_user(
  user_name = "TestSup000",
  user_password = "Test!Sup!000!",
  role = "Supervisor"
)

# create an interviewer in the supervisor's team
create_user(
  user_name = "TestInt007",
  user_password = "Test!Int!007!",
  role = "Interviewer",
  supervisor = "TestSup000"
)

To download data:

# STEP1: START AN EXPORT JOB
# specifying same same options as in user interface
# optionally specifying other options--including some not available in the UI
start_export(
  qnr_id = "72f7160c-12dc-4dd4-9df1-66af819e434d$1",
  export_type = "STATA",
  interview_status = "All",
  include_meta = TRUE
) -> started_job_id

# STEP 2: CHECK EXPORT JOB PROGESS, UNTIL COMPLETE
# specifying ID of job started in prior step
get_export_job_details(job_id = started_job_id)

# STEP 3: DOWNLOAD THE EXPORT FILE, ONCE THE JOB IS COMPLETE
# specifying:
# - job ID
# - where to download the file
get_export_file(
    job_id = started_job_id,
    path = "C:/your/file/path/"
)
