How to Set Up the Bigdog Gateway

Bigdog is a credit card gateway available in Admoji. Besides standard card processing, a Bigdog processor can also accept Google Pay and Apple Pay, and its chargeback monitoring status is surfaced in the MID Health Report.

Note: Bigdog was previously named Shiftstack. If you see older references to Shiftstack, they refer to this same gateway.

Step 1: Create the Processor

  1. Go to Merchants > Processors.

  2. Select the Credit Card tab and click New.

  3. On the General tab, choose Bigdog from the Gateway dropdown.

  4. Click the edit icon next to the gateway to open the credentials drawer.

Step 2: Choose the Mode

The Test Mode and Live Test Mode toggles decide where the processor charges and which of the URL and key fields you can fill in:

  • Live (both toggles off) — real charges go through the Bigdog wallet proxy with your Wallet Proxy Merchant Key, which is required. This mode accepts raw cards as well as Google Pay and Apple Pay. Direct API URL is disabled.

  • Test Mode — charges go to the Bigdog sandbox. Enter your sandbox host in Direct API URL to use it with your own credentials, or leave it blank to use the default Bigdog sandbox. Wallet Proxy Merchant Key is disabled.

  • Live Test Mode — Validate checks your live credentials, and charges go to the sandbox as in Test Mode. Direct API URL and Wallet Proxy Merchant Key are both optional.

Note: When you turn Test Mode or Live Test Mode on or off, Admoji clears the field that becomes disabled, so a value from the previous mode is never used by mistake. Before going live, turn both toggles off and enter your Wallet Proxy Merchant Key.

Step 3: Enter the Bigdog Credentials

Fill in the fields in the Connect Gateway drawer:

  • API Username — required.

  • API Password — required.

  • Direct API URL — optional, only in Test Mode and Live Test Mode: your own sandbox host.

  • Wallet Proxy Merchant Key — required in Live, optional in Live Test Mode, disabled in Test Mode.

  • Google Pay Merchant ID (optional) — only needed if you want to accept Google Pay on this MID.

  • Apple Pay Merchant ID (optional) — only needed if you want to accept Apple Pay on this MID.

  • Test Mode — sends transactions to the Bigdog sandbox.

  • Live Test Mode — validates your live credentials and sends transactions to the Bigdog sandbox. Test Mode and Live Test Mode are mutually exclusive.

Tip: Instead of typing the username and password, click Auth Key next to API Username and paste a Base64 username:password key — Admoji decodes it into both fields. Click Manual to go back to the two separate fields.

Step 4: Validate the Credentials

  1. Click Validate at the bottom of the drawer.

  2. Wait for the Credentials successfully validated message. The drawer closes and the gateway shows up as a badge on the General tab.

Important: Bigdog credentials have to be validated before the processor can be saved. If you close the drawer without a successful validation, Admoji warns Please validate the gateway credentials and the gateway is not attached. Editing any credential field after validating clears the validation, so validate again before saving.

Step 5: Complete the Processor Settings

  1. Enter a Processor Name on the General tab.

  2. Open the Settings tab and enter the MID Number and Currency — both are required.

  3. Configure the optional limits and fees (Monthly Limit, Discount Rate, Reserve Rate, Transaction Fee, Chargeback Fee, Alert Fee) as needed.

  4. Click Save.

Monitoring Chargebacks on a Bigdog MID

Bigdog MIDs expose their card-brand monitoring status directly in Admoji. Open Reports > MID Health, find the Bigdog MID, and click the Chargeback Monitoring icon in the Action column. See How to Use the MID Health Report for the details of that view.
