The other day I overheard someone needing to encode/decode a URL string inside of a Nintex Workflow (and again at the Nintex 2017 InspireX during a presentation on Azure Functions). Presently this is a non-trivial task (more information here), so I decided to simplify the process a bit by creating a set of REST web service endpoints that would handle the encoding/decoding process.
These web services can easily be called from the Nintex Workflow Web Request actions in On premises products as well as O365.
To use these web service endpoints, configure a 'Web Request' action to POST application/json content to these endpoints:
Encode: http://swunaapi.azurewebsites.net/api/Url/Encode
Decode: http://swunaapi.azurewebsites.net/api/Url/Decode
To use the endpoints POST the following JSON:
{"value" : "Url To Encode/Decode"}
