I am trying to define a REST data input that uses an encoded URL param to fetch data. That param is a datetime value, called 'last_seen', see the following image:
What I'm after is a way to encode the datetime value so that the API can process it correctly.
Example: for a value of 2017-07-26T15:07:37.000+01:00 the encoded string value should look exactly like this 2017-07-26T15%3A07%3A37.000%2B01%3A00
Were you able to get this figured out, I had the same issue?
