Postscript Source Signals That Marketers Can Actually Use
Receive Postscript SMS subscriber lifecycle and inbound-message webhooks as normalized customer source signals.
Postscript becomes an inbound source for campaign, customer, consent, and lifecycle activity. EVENTS Gateway verifies the webhook, normalizes the payload, and connects those signals to the same event layer used for attribution and destinations.
Signals come in clean.
Inbound customer, consent, campaign, and lifecycle events flow from this platform into EVENTS Gateway.
What marketers gain from Postscript
Marketers can connect SMS list growth, opt-outs, and inbound messages to ecommerce behavior and revenue reporting.
How the Postscript source integration works technically
Postscript sends webhook payloads into EVENTS Gateway. The request is protected with a Postscript signing token, converted into canonical event names, attached to identity and campaign context when available, and stored as a source event that can inform routing and reporting.
Provider Webhook
Postscript posts events such as shop.incoming_message, shop.subscriber.opt_in, shop.subscriber.opt_out to a dedicated EVENTS Gateway URL.
Verification Layer
EVENTS Gateway validates the request using a Postscript signing token, then rejects malformed or untrusted payloads before they reach the shared event model.
Canonical Source Event
The raw provider payload is normalized into a reusable source event with contact, campaign, message, and click context where the provider sends it.
Marketing Context
Marketers can connect email, SMS, consent, and automation activity to site behavior instead of reading provider dashboards in isolation.

Why Postscript belongs in the same event layer as your destinations
