Add Email Alias API returns bad request

I am also having the same issue although if I manually add the alias via settings it works fine.  I am trying to add an email alias to the user and according to the documentation the request should send the attribute as email and the email address following a colon after it. This is almost exactly like the Update User API except it is a Post instead of a Put and the update user function works fine for me. Following are the Powershell snippets I am using\API Examples and the error message that is returned when attempting to add the email alias, any help would be appreciated.

Email Alias Add Function:

Update User PowerShell Function:

Update User API Example: "curl https://api.box.com/2.0/users/USER_ID \ -H "Authorization: Bearer ACCESS_TOKEN" \ -d '{"name": "sean"}' \ -X PUT"

Add Email Alias Example: "curl https://api.box.com/2.0/users/USER_ID/email_aliases \ -H "Authorization: Bearer ACCESS_TOKEN" \ -d '{"email": "***@example.com"}' -X POST"

Error Returned: Invoke-RestMethod : {"type":"error","status":400,"code":"bad_request","context_info":{"errors":[{"reason":"invalid_parameter","name":"email","message":"Invalid value'EmailAddressRemoved'."}]},"help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"BadRequest","request_id":"removed for privacy579935fdc188b"}

Hey ,

Your Postman syntax looks correct and if you copy the example straight from the documentation it will work provided the email value you are adding is valid.

curl https://api.box.com/2.0/users/USER_ID/email_aliases \
-H "Authorization: Bearer ACCESS_TOKEN" \
-d '{"email": "procks+jamesdean-alias-2@box.com"}'
-X POST

{"type":"email_alias","id":"52xxx1","is_confirmed":true,"email":"procks+jamesdean-alias-2@box.com"}

If you login to your Admin console and check the Enterprise Settings --> Account Info page you will see a list of registered domains for your enteprise.  In my example below I only have "box.com"

Therefore, if i try to run the same API call with a random unregistered domain I will hit the same error you are seeing. i.e.

curl https://api.box.com/2.0/users/USER_ID/email_aliases \
-H "Authorization: Bearer ACCESS_TOKEN" \
-d '{"email": "procks+jamesdean-alias4@box10.com"}'
-X POST

"errors": [
      {
        "reason": "invalid_parameter",
        "name": "email",
        "message": "Invalid value 'procks+jamesdean-alias4@box10.com'."
      }

Please re-test with a registered domain and let me know if this works.

To add additional owned domains to your Box enteprise please reach out to your Customer Success Manager if known or raise a request with our User Services team

fyi, see information above for testing.
