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.
