When you obtain a MarketSite account, you are asked for the destination to which you want MarketSite to send all envelopes.

The recommended destination is the receiveEnvelope service. The URL for the receiveEnvelope service is as follows, where alias is the alias for the MarketSite that is sending the envelopes:

https://host:port/invoke/pub.marketconnect.transport/receiveEnvelope?marketConnectAlias=alias

You can use a custom service as the destination instead of the receiveEnvelope service. The custom service must adhere to the envelope handler service specification (see EnvelopeHandlerSpecification).
