Postscript is an SMS marketing platform. SourceMedium receives Postscript data through Data Warehouse Push to BigQuery: messages, clicks, subscribers, unsubscribes, and order attribution. Postscript pushes the data to SourceMedium; there is no API key to paste. Data Warehouse Push is in beta for Postscript Enterprise brands, so your Postscript CSM enables it for your account. Setup works the same on every plan: SourceMedium hosts the destination.
Sign in to SourceMedium, open your store, then choose Data sources → Connect data source and select the platform. You need an Admin or Editor workspace role.After you connect explains the first sync and connection statuses.

What you need

  • Your Postscript account or Shopify shop domain

​
How to connect

1

Request setup in SourceMedium

Find Postscript in the connector picker and click Connect. Enter your Postscript account or Shopify shop domain (required) and click Request setup. The card shows Setting up while SourceMedium completes the connection.
2

SourceMedium creates the destination

SourceMedium creates your Postscript destination in its own BigQuery project and sends you the project and bucket details for your Postscript CSM. You do not create a GCP project, bucket, or dataset.
3

Your Postscript CSM enables Data Warehouse Push

Send those details to your Postscript CSM, who enables Data Warehouse Push to that destination. Postscript’s BigQuery guide describes the push. Historical data is pushed first, then new data every hour.

​
What data syncs

Messages, clicks, order attribution, subscribers, and unsubscribes. Grain and columns follow Postscript’s warehouse tables. Historical data is included in the first push.

​
Notes

  • Data Warehouse Push cannot be customized; Postscript sends the full set above.
  • SourceMedium no longer pulls Postscript through its API. Data Warehouse Push is the only path.
