4. Error: You have not entered an xpub : Blockonomics needs  an extended public key(starting with xpub) so that it can generate new bitcoin address for each customer order. Visit Merchants to see how to get xpub of your wallet. Please see this video on how to locate xpub of wallet

5. Error: Your server is blocking outgoing HTTPS calls:  You can ask your webhosting provider to execute the below command on the server console:

$ curl -vvv
* Rebuilt URL to:
*   Trying
* Connected to ( port 443 (#0)
* ....
* ....
* ALPN, server did not agree to a protocol
> GET / HTTP/1.1
> Host:
> User-Agent: curl/7.47.0
> Accept: */*
< HTTP/1.1 200 OK

If its working and you get 200 OK, everything is working as expected and problem lies elsewhere. If not, ask your webhosting provider to unblock it, so that the call goes through.

6. Error: Your have an existing callback URL. Refer instructions on integrating multiple websites: This means you have an another website callback pointing to your xpub. You need to add one more xpub to support multiple site. Check this article for detailed information
