Thanks for you answer
Actually my ptc site has already integrated Blockchain only. Do I need any coder to integrate bitpay and blocktrail?
Actually there is not much difference between blocktrail and blockchain api so you may ask the same coder to replace blockchain with blocktrail here is api guide for blocktrail
https://www.blocktrail.com/api/docsBitpay provides easy to integrate payment plugin so if you have little bit knowledge on coding than you can have a look at this
