I’d suggest for the time being to manually encode the REST API parameters. This involves manually encoding the JSON parameters, however. The REST API can be found here:
http://docs.couchbase.com/4.0/n1ql/n1ql-rest-api/index.html
I’ll update the docs a bit later with an example of this.
The N1QLPARAMS API will likely be removed in a future release.
