Authorize.Net provides a self-service sign-up for a sandbox account. To sign-up
for an account visit the
sign-up page and fill in
the details. To create a sandbox account, visit the
sandbox registration page.
The account ID is obtained from the Authorize.Net Admin Portal under Settings
-> API Credentials & Keys. The account ID will be listed next to the label
“API login ID”.
The Authorize.Net transaction key can be generated at the same page as Merchant
Account ID, by selecting New Transaction Key and then clicking the Submit
button. After that, a confirmation pin will be sent to the registered email
address, complete the verification to get the new transaction key.
In order for webhooks to be sent to us, at least one signature key must be
generated. This is done on the same page as the Transaction Key. Go to the
API Credentials & Keys and select New Signature Key, then complete the steps
displayed.
