kntnr

Retrieve data from kintone via its API. kintone is an enterprise application platform.

Installation

Stable CRAN version

install.packages("kntnr")

Dev version

devtools::install_github("yutannihilation/kntnr")

Usage

Authentication

To use kintone API, kntnr needs the following environmental variables.

• KNTN_URL: kintone URL
• KNTN_AUTH_TYPE: authentication type (password or token)
• KNTN_AUTH: API token or BASE64 encoded login name and password

kntn_set_auth() sets these environmental variables interactively.

library(kntnr)

# password-based authentication
kntn_set_auth()

# token-based authentication
kntn_set_auth(auth_type = "token")

To set another information, run kntn_set_auth() with overwrite = TRUE.

kntn_set_auth(overwrite = TRUE)

Or, unset the environmental variables by kntn_unset_auth().

kntn_unset_auth()

For non-interactive use

You can define the environmental variables in .Renviron, which is loaded at the start of an R session. For more information, see ?Startup.

KNTN_URL = https://example.kintone.com/
KNTN_AUTH_TYPE = token
KNTN_AUTH = 1234567890

Record API

kntn_record() gets a single record from the specified kintone application. kntn_records() retrieves multiple records at once. If the number of records is more than records_per_request (the default is 100), kntn_records() automatically splits the request into smaller subrequests.

app <- 10

# get a single record
d <- kntn_record(app, id = 1)

# get records up to 1000 (default)
d <- kntn_records(app)

# get records up to 5000 records at the latency of 500 records/request.
d <- kntn_records(app, max_records = 5000, records_per_request = 500L)

Some types like SUBTABLE are converted as nested data.frame. You can unnest them by using kntn_unnest().

kntn_unnest(d)

File API

kntn_file() gets a file from kintone API and try to parse it with httr::content(). If you want to parse it by yourself, specify as = "raw" or as = "text".

d <- kntn_record(app, id = 1)

f <- kntn_file(fileKey = x$Attachment[[1]]$fileKey[1])
