Gateway Binding using the API

[bmtolleson]

I get an Error 400 (Bad Request) using the code below.  I have looked at it for hours.  Does anyone see anything wrong?  Any suggestions?

#Login to Power BI using PowerBIPS App registration.
Write-Host "Start Login"

Hi @bmtolleson ,

The following ones are the threads which have the similar problem as yours, please check their solution. Hope they can also help solve your problem.

BindToGateway Powershell REST API POST failing

I have found the reasons why this wasnt working so thought I would list them here for future users. To get this to work there are a few things to be aware of:

1. If the datasource is not assigned to a gateway you need to not include the datasource ID values (you wont actually be able to get these ID values if it is unassigned). I assume the ability to specify the data source id values is only relevent when the dataset is already assigned to a gateway, but I dont know if you can use two separate gateways for one dataset with two datasources.

2. Service principals cant be set to administrators of gateways, so you cant use them

3. Users must be set as administrators of gateways

4. The user must be assigned as a user of the data source defined on the gateway (different from being a gateway admin)

I tried the suggestions in that post, but no luck.
