Always getting 'InvalidTokenException' while token is not modified.

Question

I am getting token from aws marketplace when I subscribe to my product from aws marketplace via a test account. But when I call the resolve-customer-api over the token, I get 'InvalidTokenException'.  
  
I tried to resolve token even via CLI but same error.

I had been working perfectly earlier but its not now. By comparing the token to previous one I have realized that the length of previous tokens were 180 but this one has 194.  
Here is the body of post request to my page from AWS marketplace.  
body: 'x-amzn-marketplace-token=MNEwEjq%2FBGaoLe2mueodq%2BuSzoG6pYX4xR4PO7qGKL7N%2FhQyc0I8DyVcwCTSjLtxddVRZqAnbhPHABHquQ5gKAim0S0z8KhfJfH5Nz9Elaa9uwGKhKM33KpD%2BJMU6MSF%2BFMc2Mv22nQP%2FF0DLgFDXqkBe%2FT262K0Bxj8IHMK07ZW27uuR96A'  
  
I am not sure why am I getting this error.  
Thanks,

Answer

The token I received in the body was URL encoded, by decoding it, it works fine.  
  
But still I don't know why is it in body like a string:  
body:{  
  'x-amazon-marketplace-token=xxxxxxxxxxxxxxxxtoken'  
}  
  
and not like this:  
body:{  
  'x-amazon-marketplace-token':'xxxxxxxxxxxxxxxxxtoken'  
}
