I am reposting this question. The original post was closed and I have not resolve this issue yet. I hope there will be someone can help.
I created a webhook url in Zapier that I copied into my application (Asecurecart - shopping cart). Asecurecart is reporting this error each time I send data to Zapier:
Error: Object reference not set to an instance of an object.
The screen shots are of the setting for the webhook in Asecurecart and the error message that is reported.
Any help will be greatly appreciated.
