API calls fail when payload contains values with ampersands in them

[anttiviljami]

Whenever I try to send any payload with a value with the letter "&" in it, I always get a 401 error saying my oauth signature is incorrect.

Error: Request failed with status code 401

Looks like the problem is that ampersands don't get encoded in the payload. The fix is using encodeURIComponent, instead of encodeURI when generating the query string.

Do you want to create a PR for this repo as well?
