Hi @joeH68 ,
happy to support you on using Postman for the Viessmann API! You can use this collection, which you can import to your Postman. It contains all basic API requests using and testing the Viessmann API. Unfortunately, I cannot upload a JSON file here, this is why you need to copy the code below and paste it. to a text file, which you save with the ending .json. This file can be imported to your Postman by clicking on "Import".
Let. meknow if this helps.
Best regards,
Michael
