And one more question how to generate oauth_signature and what parameter used to generate oauth_signature method?

Greetings krupeshlaiya,

The iframe link generated points to demo.pesapal.com/?oauth_callback=XXXXXXXX which is incorrect. There is no call to any of our API methods. It should point to demo.pesapal.com/api/PostPesapalDirectOr...th_callback=XXXXXXXX

Have a look at this developer.pesapal.com/how-to-integrate/api-reference

thank you now I have problem related to Problem:

How do I generate valid signature what to do for the valid signature?

Have a look at the response to question 4 here developer.pesapal.com/forum/2-pesapal-in...736-common-questions

Not much helpful please elaborate more for the same.

using which parameter I can generate the oauth singnature.
Please help me.

krupeshlaiya,

When you get the invalid signature error, The reason could be:

1. Your consumer secret is incorrect.
2. You are connected to the live system yet your API links send data to HTTP instead of HTTPS.
3. Your OAuth file is encoding the data sent to PesaPal incorrectly.
