Hi folks, I have a working Electron publishing custom JSON data to the Particle Cloud, with an integration defined to relay message to an Azure IoT Hub. I’d like to pass an array as the value of one of my custom properties, but it gets passed as a string value. Seems I would need to remove the qu…

This is the best place I’ve found for working out JSON formatting issues. http://www.jsoneditoronline.org/

Thanks Bear, but this really doesn’t have anything to do with JSON exactly, but more of what semantics are of the integration templating. For example, this JSON: { "thisIsAnArrayOfStrings": [ 'red', 'green', 'blue' ] } …and this JSON… { "thisIsJustAString": "[ 'red', 'green', 'blue' ]" }…

Can you post some screenshots of your custom Azure integration in the Particle console? And the code you’re using in the Particle Publish?

RWB, the azure integration custom JSON is already in the original post. The reply before yours contained the code for the publish call, repeated here: Particle.publish("sampling", "{ \"readings\": [ 'red', 'green', 'blue' ] }", 60, PRIVATE); Is there something else specific I can provide? -John

This might help, Just copied a snippet from one of mine. char ledJSON[100]; char ledtemp[100]; snprintf(ledJSON, sizeof(ledJSON), “{\ledColor”:{“red”:%d,“green”:%d,“blue”:%d}}", 1,2,3); and another way: sprintf(ledtemp, “%02d:%02d:%02d”, sun_set_h -12 , sun_set_m, sun_set_s); sprintf(ledJSON, …

Thanks mikemoy, Sorry to mislead you, I just simplified the Particle.publish() method for illustration. I make use of snprintf() fine, and can compose the JSON payload fine in my code. My issue is that the JSON object ( {“red”,“green”,“blue”} in your example), winds up being just a quoted string, …

@JohnKoz Maybe you're having the same issues we discuss here: [image] How to pass unescaped JSON to Azure IoTHub? Cloud Hello RWB. There are simularities regarding encoding strings for JSON. It seems that the nesting is the issue in my case: the outer json is ok, but the…

Yeah, unfortunately David summed the answer up a month ago in that post - I’m SOL. The custom JSOM sophistication is a low priority, and passing an integer, object or array is not possible with the current offering. I don’t even know where I can go from here, I’ll have to revisit my entire design. …

Let’s ask @Dave if there is any progress on this front?

I’ll ping the team about this again, thanks for raising the issue. Thanks, David
