Connect NMI to Bolt so Bolt can authorize and capture payments through your NMI account.

If IP blocklists are enabled, allow:
13.57.173.9318.236.33.23034.209.104.17752.36.152.15012.2.150.168/2912.249.26.128/3050.18.19.8
Also add your office IP addresses.
Step 2: Obtain NMI keys
- Log into your NMI merchant account.
- Go to My Settings > Security Keys > Add a New Private Key.
- Click generate a new API key.
- Click view.
- Copy the 32-character API key.
Step 3: Add keys and edit payment settings
- Log into the Bolt Merchant Dashboard.
- Go to Settings > Payments.
- Click Set Up NMI.
- Add your private NMI key.

Step 4: Configure NMI webhook
Webhooks keep Bolt and NMI in sync for chargebacks.

Tell your fraud provider that payments through this processor will not include CVV match information.
