Inbound messages

Every text your customers send to your shortcodes is stored. Pull them over the API with filters on shortcode, keyword, routing outcome and time window.

This is the pull counterpart to the push-style inbound webhooks. Use the webhook for real-time handling and this API for backfills, audits, dashboards, or when you'd rather poll than host an endpoint.

What routing_status tells you

Parameters

Field	Type	Required	Description
direct	dedicated	No	Arrived on your own shortcode, no keyword needed, it's all yours.
matched	shared	No	Matched one of your keywords on the shared shortcode.
callback	forwarded	No	Delivered to the keyword's callback URL successfully.

unmatched	dropped	No	Shared-shortcode message that matched none of your keywords. You only see these on your own shortcodes.

Reconciling webhook deliveries

Webhooks are at-least-once and your endpoint can be down. A periodic sweep of this API filtered to status=matched (received but not confirmed forwarded) is a cheap way to catch anything your webhook missed.
