Using the Yammer API to Set-up Recurring Exports

On first run, the script will export all network data up from the beginning of the network up until present. From then on, it will automatically check for previous exports, and perform an export from the date of the previous export. This script can be used with common schedulers (Cron, etc) to easily set up recurring exports.

Shell

#!/bin/sh
 
if [! $1 -o ! $2 ]; then
  echo "Usage: export.sh <OAuth Access Token> <Directory>"
  exit 1
fi
 
 
# Your Yammer OAuth 2 Access Token. This must be a token for a verified admin account.
AT=$1
 
# Download location for the export files
DIR=$2
cd $DIR
 
# Find the last export if there is one. The start date and time of the previous export
# is encoded in the filename in UNIX time (http://en.wikipedia.org/wiki/unix_time)
LAST_EXPORT=`ls export-*.zip | sed -e 's/export-\(.*\)\.zip/\1/g' | sort -n | tail -l`

# Check to see if a previous export was done
if [ ! $LAST_EXPORT ]; then
  # No previous export was done. Start at the beginning of time (or 1970, which is close enough given Yammer's age).
  LAST_EXPORT=0
fi
 
# Convert UNIX time to ISO-8601 time, which the API endpoint accepts.
DATE=`date -j -r  $LAST_EXPORT "+%Y-%m-%dT%H:%M:%S%z"`
 
# Calculate the current date in UNIX time for the filename of the export.
NEXT_EXPORT=`date "+%s"`
 
# Perform the next export. Send the OAuth2 access token and store the UNIX time of this export in the filename.
curl -v --output export-$NEXT_EXPORT.zip \
  --header "Authorization: Bearer $AT" \
  --get --data-urlencode since=$DATE \
  "https://export.yammer.com/api/v1/export"
 
# Verify the download completed
if [ $? != 0]; then
  echo "Download failed...cleaning up."
  rm export-$NEXT_EXPORT.zip
  exit 1
fi
 
# Verify the contents of the zip file.
unzip -t export-$NEXT_EXPORT.zip >/dev/null 2>&1
if [$? != 0 ]; then
  echo "Invalid up file detected, export failed....removing downloaded ZIP"
  rm export-$NEXT_EXPORT.zip
  exit 1
fi

Sample Data Export Script for Windows

On the first run, the script will export all network data up from the beginning of the network up until the present. From then on, it will automatically check for previous exports, and perform an export from the date of the previous export. This script can be used with Windows schedulers to create automatic, recurring exports.

You may need to install wget for Windows if you do not already have it installed. Here is a link to the latest version:

http://sourceforge.net/projects/gnuwin32/files/wget/1.11.4-1/

Make sure to update your PATH environment variable to include the GNU bin path (e.g., C:Program Files (x86)GnuWin32bin).
