In "api/v1/Soap.Asmx?op=ConnectAppAndInfoUsingTicket" it mentions you can connect using a connection ticket.
(<connectionTicket>string</connectionTicket>)
How/where can I get the value for the connectionticket?
If you already have an existing WebApi connection you can use: RequestLoginAsTicket | DataMiner Docs
If you have a regular connection you can use RequestTicketMessage
An example of how that's used can be found here:
Hi Tim,
You can get a connection ticket by using the 'RequestLoginAsTicket' endpoint in the JSON/SOAP API. Note that this request needs a valid connection, which you can get by using the 'ConnectApp' endpoint in the JSON/SOAP API.
Note that the 'ConnectApp' endpoint needs valid credentials to setup the connection. This is because the ticket login is not meant to be used standalone but to authenticate an already connected user without needing their credentials.
