Odoo needs your API Credentials & Keys to connect with your Authorize.Net account, which comprise:
API Login ID: The ID solely used to identify the account with Authorize.Net.
API Transaction Key
API Signature Key
API Client Key
To retrieve them, log into your Authorize.Net account, go to, generate your Transaction Key and Signature Key, and paste them on the related fields in Odoo. Then, click on Generate Client Key.
If you are trying Authorize.Net as a test, with a sandbox account, change the State to Test Mode. We recommend doing this on a test Odoo database, rather than on your main database.
If you set Test Mode on Odoo and use an authorize.net account instead of a sandbox.authorize.net account, it results in the following error: The merchant login ID or password is invalid or the account is inactive.
Place a hold on a card¶
With Authorize.net, you can enable the manual capture. If enabled, the funds are reserved for 30 days on the customer’s card, but not charged yet.
After 30 days, the transaction is voided automatically by Authorize.net.
