# Mica Data Access Request API

Mica provides some web services for handling the data access request (DAR) workflow. The Mica R package exposes data access requests related functions that may be used for reporting:

- as data access requests form is configurable, the form can be downloaded,
- data access requests can be listed or extracted individually.

Setup the connection with Mica, login with a user having permission to administrate data access requests:

    library(micar)
    m <- mica.login(username="administrator", password="password", url="https://mica-demo.obiba.org")

Get the DAR form that describes the data model:

    mica.dar.form(m)

Get the list of all the data access requests, one column per field:

    mica.dars(m)

Or only a single one:

    mica.dar(m, "390463")

Get the history of changes of a DAR:

    mica.dar.history(m, "390463")

Get the amendments of a DAR:

    mica.dar.amendments(m, "390463")

Good practice is to free server resources by sending a logout request:

    mica.logout(m)
