Link Generation via SMS

POST /v1/link/go/sms

Generates a secure, signed Doorstep Go URL for a specified address and sends it as an SMS to a provided phone number.

Requires an API key sent as a Bearer token in the Authorization header.

note

The URL sent in the SMS is a shortened version of the generated link, since the full signed URL is too long to send comfortably in a text message. The full-length link is always returned in the API response.
