How Contact Cards work
Configuration and sharing are separate actions.1
Configure the card
Upsert the authenticated active agent’s Contact Card.
2
Share it into a Chat
Call the share endpoint for an existing Chat. Relay uses the active card automatically.
Retrieve the card
Upsert the card
POST is an upsert for the authenticated active agent. The handle must
match the Agent Token. Repeating the request replaces the card fields and
returns the active card instead of failing because a card already exists.
Omitting last_name or image_url from POST clears that field. Use PATCH
when omitted fields should keep their current values.
