This application is a reference implementation for how to publish voice recordings and other speech-related data to Medallia Experience Cloud (MEC) using the Medallia Speech API.

This process occurs in two stages:

1. Transfer the recording file to the Medallia Media File Transfer (MMFT) server; and

2. Publish the recording metadata to the Medallia Speech API to begin processing.

Both stages can be executed using parallel workers and have a maximum execution time enforced.

This program was written to compile and run using AdoptOpenJDK 16. Please install and configure it on your system before proceeding.

Run the following commands:

./compile.sh

The below examples use environment variables to mask sensitive information. Contact your Medallia representative to obtain the following details before proceeding:

• The MMFT endpoint
• The MMFT access and secret keys
• The MMFT bucket name
• The MEC OAuth 2.0 client id and secret
• The MEC OAuth 2.0 token URL
• The Medallia Speech API URL via the Medallia API Gateway

Once compiled, run ./run.sh --help to see the usage screen and common arguments:

You can further explore each subcommand's help using ./run.sh [command] --help, where [command] is one of the commands listed at the bottom of the first usage screen shown:

This application is capable of transferring recordings to MMFT from a source of either an SFTP or a local directory.

The following shows how to transfer data from a local directory:

./run.sh transfer \
    --folder=./sample-recordings \
    --glob="*.wav" \
    --mmft-endpoint=${MMFT_ENDPOINT_URL} \
    --mmft-access-key=${MMFT_ACCESS_KEY} \
    --mmft-secret-key=${MMFT_SECRET_KEY} \
    --mmft-bucket=${MMFT_BUCKET}

The following shows how to transfer data from a SFTP source:

./run.sh transfer \
    --sftp-folder=sample-recordings \
    --sftp-host=${SFTP_HOST} \
    --sftp-username=${SFTP_USERNAME} \
    --sftp-password=${SFTP_PASSWORD} \
    --output=files-transferred.txt \
    --mmft-endpoint=${MMFT_ENDPOINT_URL} \
    --mmft-access-key=${MMFT_ACCESS_KEY} \
    --mmft-secret-key=${MMFT_SECRET_KEY} \
    --mmft-bucket=${MMFT_BUCKET}

The Medallia Speech API accepts metadata in JSON format, but this application accepts metadata in either JSON or CSV format, converting as needed.

./run.sh publish \
    --data=metadata.csv \
    --api-gateway=${MEC_API_GATEWAY} \
    --client-id=${MEC_OAUTH_CLIENT_ID} \
    --client-secret=${MEC_OAUTH_CLIENT_SECRET} \
    --token-url=${MEC_OAUTH_TOKEN_URL}
