Greetings @optimygmbh,

thank you for your contribution!

Regarding the update method, it seems you're referring to the existing update functionality. Below is an example demonstrating how the subject and body properties can be updated:

message.subject = "Updated subject"
message.body = "Updated body text"
message.update().execute_query()

In this approach, the message properties are exposed in a discoverable and autocompletable way, making it easier for developers to interact with.

On the other hand, using the method signature update(payload) seems less beneficial for the following reasons:

• It reduces the discoverability of the properties.

• It increases complexity when setting complex property values.

Best regards,

Hi @vgrem
Makes a lot of sense, did not realize that it can be updated like that. Thanks for the clarification.
Best regards,
