Any support for async/await

[Wombatush]

At the moment all API requests in C# clients are executed synchronously. Is there plan to introduce asynchronous methods with async/await and cancellation token support?..

[SebastianStehle]

Would like to see this as well. At the moment, I have written my own client library.

Any update on this? I was quite surprised after taking a dependency on this, that it has not been addressed yet.

[SebastianStehle]

I have talked with the support a few years ago and they said, they want to move the OpenAPI and then rework the clients, but It seems that this project is on hold: https://github.com/messagebird/openapi-specs?tab=readme-ov-file

Thanks @SebastianStehle. With some more searching I also found https://www.postman.com/messagebird-official/messagebird-official/overview, not sure how up to date it is. But your link seems to have what I need for my use case to generate a usable client.

[SebastianStehle]

If you have something. please publish it :D

@SebastianStehle decided to roll my own client, but fwiw, with NSwag Studio you can use something like this if it fits your needs (untested).
