Downloading JSON file using Invoke-WebRequest by passing credentials and SessionToken

Question

I am trying to download a JSON file from a URL which requires UserName, Password, User ID and SessionToken. I am referring an article: https://support.tidepool.org/hc/en-us/articles/360029368992-Downloading-your-Tidepool-Web-Notes

PS C:\Users\rajiv\OneDrive\Documents\Personal\Diabetes> Get-Credential | Invoke-WebRequest -Uri https://api.tidepool.org/auth/login -Method Post

I am getting the below error. I am pretty sure that I am passing the correct credentials:

cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
Invoke-WebRequest : {"code":400,"reason":"Missing id and/or password"}
At line:1 char:18
+ ... redential | Invoke-WebRequest -Uri https://api.tidepool.org/auth/logi ...

Answer 1

Have a look at the Invoke-Credential help. The "Credential" parameter is a named parameter and the cmdlet does not accept pipelined input for it.

This should accomplish what you're trying to do:

Invoke-WebRequest -Credential (Get-Credential) -Uri https://api.tidepool.org/auth/login -Method Post

I think this, too, will work (the credential is passed as an object and the object has a property named 'credential' (which matches the name of the cmdlets parameter) with an appropriate value.

[PSCustomObject]@{Credential = (Get-Credential)} | Invoke-WebRequest -Uri https://api.tidepool.org/auth/login -Method Post
