Path Params
string
required

The id of the shared connection to attach the merchant to

Body Params
string
required

The merchant to attach to the connection

routing
array of objects
required

One entry per field this merchant is identified by. A merchant joins a connection once, so every rule it needs must be sent together.

routing*
date-time

The date the merchant starts fighting chargebacks on this connection. Defaults to 5 days from today, matching how the platform sets it when nobody names one. Must be today or later. Read in UTC, with any time component dropped, so an offset-bearing value such as 2026-10-01T01:00:00+05:00 is stored as 2026-09-30 — send a plain date to avoid that. The response echoes what was stored.

Responses

400

The connection cannot take a merchant, or the request is malformed
