Send a document to an external system via a connector

You can reference a document in an outbound connector. Connectors can use variables with document metadata as an input. The format of inputs will depend on the connector, as each connector has a different input structure.

The connector SDK provides document support in property/variable bindings.

In most cases for the following outbound connectors, you can include a Request body under Payload in the properties panel to send with your request:
