AWS bearer token authentication issue

Question

I have a requirement to get data from aws using IAM API's , so I have access key , secret key , base url , service name and region of aws account we are trying to authenticate with bearer token , but we are getting the following error , I have generated bearer token using aws cli.

URL : https://iam.amazonaws.com/?Action=ListGroups&Version=2010-05-08&access_token=<<token>>

https://iam.amazonaws.com/?Action=ListGroups&Version=2010-05-08&Authorization=Bearer <<token>>

Error : is not valid; the value of a query string parameter may not contain a '=' delimiter

Answer

The URL that you have presented seems correct. I suspect that you might not be escaping the token. 
Usually the token contains slashes (/) that need to be escaped.

If you are using Javascript you can use [encodeURIComponent ](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent) function to encode the token.

Without more information, is hard to know what the actual issue is. Hope this helps.
