[Feature Request] Enable IdWeb to use ExtraBodyParameters #3463
Description
Is your feature request related to a problem? Please describe.
Currently, IdWeb does not allow for the passing of ExtraBodyParameters during authentication or token acquisition flows. This limits extensibility for scenarios that require additional parameters to be sent in the request body to the identity provider.
Describe the solution you'd like
Enable IdWeb to support the use of ExtraBodyParameters, allowing developers to specify additional parameters in relevant authentication flows. This would align IdWeb with the capabilities of Microsoft.Identity.Client (MSAL), which already supports ExtraBodyParameters, and increase flexibility for advanced integration scenarios.
Describe alternatives you've considered
- Modifying requests at a lower level, but this introduces maintenance and compatibility challenges.
- Forking and customizing the library, which is not ideal for most consumers.
