My apologies for the late reply ... 

To me it seems like the APA102 is comparable to the WS2811 type. They use the same 5050 LEDs and have the same 4 pins (GND, 5V, C0, D0), the controller chip however might be different. I have not worked with the WS2811.

The APA104 seems to be a WS2812 "clone" - with internal oscillator, works with 24 bit in sequence, etc (as suggested in this blog post).
I guess that the only way to find out, if you have them laying around, is by simply testing it with the Arduino sketch of the WS2812 project. I highly doubt you'd ruin the strips ...

Please let us know if it worked for you ...

Forgot to add the link to the article: WS2812 with Arduino.

In the sketch you might have to experiment with this line (line 12 in the sketch):

Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);

Unfortunately I do not have APA102 or APA104 available .... I'd be interested to see if these might be good alternatives to the WS2812.

Does any of you guys know how to modify the Sketch in this Arduino Article, so these LEDs can be used?
