REDCap API Documentation

This function allows you to export the instrument-event mappings for a project (i.e., how the data collection instruments are designated for certain events in a longitudinal project).

NOTE: this only works for longitudinal projects

REDCap Version

5.8.2+ (and earlier, but we don't know how much earlier)

Known REDCap Limitations

None

Details

The data frame that is returned shows the arm number, unique event name, and forms mapped in a project.

When this function is called for a classic project, a character string is returned giving the API error message, '400: You cannot export form-event mappings for classic projects' but without casting an error in R. This is by design and allows more flexible error checks in certain functions.
