Remarks

For M-Files components only. The Ground Link proxy of M-Files Ground Link opens it. Applications should not call it.

Bidirectional streaming call without a session; see the service overview for the required metadata. Missing vault or service metadata fails with "Vault and/or service headers are missing."; a vault that does not accept Ground Link connections (its Ground Link application is not running) fails with "Vault does not exist or is not accepting Ground Link connections."; another service name fails with "Unknown Ground Link service."; an offline vault fails with a vault-offline error.
The server's initial response metadata carries mfiles-max-message-size (the largest message the server accepts; a larger message makes gRPC close the stream) and mfiles-groundlink-split-message-support = 1 (the vault side accepts a large message split into parts), plus headers from the vault's Ground Link application.

Wrapper for passing .NET remoting messages over gRPC.

Nested message fields are expanded to depth 3; follow a type link for deeper levels and for the type's own page.

Field	Type	Description
`type`	`GroundLinkMessageType`	Whether the message is a call (`REQUEST`) or the return of a call (`RESPONSE`).Values: `REQUEST` (0), `RESPONSE` (1).
`id`	`string`	The ID of the call. A response carries the ID of its request.
`uri`	`string`	The URI of the call, if any. Can be empty.
`headers`	`bytes`	The serialized .NET remoting message headers.
`data`	`bytes`	The serialized .NET remoting message.
