Api initiate transaction


i’m WANT to implement the API initiate transaction and I have done everything, but the paynow page keeps on saying status=Error&error=Invalid+Hash.++Hash+should+start+with%3a+1ED305

I’m testing on localhost & using localhost urls if that’s the problem

I’m using php sha1 function, but things are not working, HELP PLEASE


Hi Denver

May I suggest reviewing Generating a Hash in the Paynow API reference. Note, the expected hash is SHA512 not SHA1
