How to retrieve variables in Azure API to construct expression for obtaining OAuth token in body

Quynh Hoang 0

Hi,

Below is the set-body code block that I have some problems with.Im having problem constructing an expression for obtaining an OAuth token. I use 3 variables {{clientId}}, {{scope}} and {{clientSecrets}} instead of hardcoding those values.

No matter what I tried I always get some syntax errors.

Please help. It's much appreciated.

<set-body>@{
	return "client_id={{clientId}}&scope={{scope}}&client_secret={{clientSecret}}&grant_type=client_credentials";
}
</set-body>

Hi Quynh Hoang,

To dynamically insert variables in the set-body policy within Azure API Management, try using context.Variables instead of directly embedding the {{variable}} syntax. Here’s a revised version of your set-body code:

<set-body>@{ return "client_id=" + context.Variables["clientId"] + "&scope=" + context.Variables["scope"] + "&client_secret=" + context.Variables["clientSecret"] + "&grant_type=client_credentials"; }</set-body>

@Quynh Hoang Thanks for reaching out. From the description i could see you're using named values in the set-body code block, instead of hardcoding the values for client_id, scope, and client_secret.

I tried at my end using the same syntax and able to fetch the values successfully as shown below,

could you please share me the error message and the entire policy to investigate further?
