How may I escape custom replacement keys in ThingHTTP?

https://ch.mathworks.com/help/thingspeak/thinghttp-app.html#bvevu2b-5

 

I've managed to get an API request up and running and everything seems to work perfectly. At least, everything except one thing:

In my ThingHTTP body there are custom replacement key which get replaced by the passed in values:

labels=ThingHTTP,%%labels%%&title=%%title%%&description=%%description%%

 

Unfortunately, as soon as one of the replacement values contain special characters, such as & or +, things are going weird.

How may I tell ThingHTTP to escape the custom replacement keys before sending them along in a POST request?

Have you tried URL encoding ? There are websites that will do the encoding for you. Let us know if you try that.

@Hans: I'm unable to add any additional encoding, since the data is passed by a 3rd party service (IFTTT) - and there is the data already urlEncoded. I suspect ThingHTTP receives the data & urlDecodes it, before sending it along.

So the only solution I can see is that ThingHTTP should ensure it can be passed without any issues.
