Authorize.Net integration
Authorize.Net is one of the oldest payment gateways still running, now a Visa company. If you already have a merchant account and an Authorize.Net gateway sitting behind it, TinyVendor can send your sell-link payments straight through that setup.
About Authorize.Net
Authorize.Net was founded in 1996 in Utah as one of the first services to let ordinary websites accept credit cards online. It has been a wholly owned subsidiary of Visa Inc. since Visa acquired CyberSource in 2010, and operates today as part of Visa's payment acceptance business.
Headquarters
Operates under parent Visa Inc., headquartered in San Francisco, California, United States. Authorize.Net itself was founded in Utah.

Parent company
Visa Inc., acquired via CyberSource in 2010.
Known for
One of the longest-running payment gateways online, widely supported by e-commerce platforms and merchant account providers.
Sellers who already have a merchant account with a bank or processor often pick Authorize.Net specifically because it's a gateway — it plugs into whatever merchant account you already have, rather than asking you to move your processing relationship somewhere new.
How to apply for an Authorize.Net account
1. Decide gateway-only or all-in-one
If you already have a merchant account with a bank or processor, apply for the gateway-only plan and connect it to that account. If you don't have a merchant account yet, Authorize.Net's all-in-one signup can help arrange one alongside the gateway.
2. Gather your business details
Legal business name, physical address, phone number, and email.
3. Gather your banking and tax details
Your bank's routing and account number for payouts, plus an EIN or Social Security Number.
4. Apply online
Authorize.Net's signup form runs through all of this in one sitting — there's no requirement to visit a branch.
5. Wait for approval
A gateway-only account is typically approved automatically on submission. If Authorize.Net is also arranging your merchant account, underwriting can take anywhere from about an hour, for auto-approved applications, to several business days, depending on your industry and credit history.
6. Retrieve your API credentials
Once approved, find your API login ID and transaction key under your Authorize.Net account's security settings. Those are what TinyVendor needs.
Selling with Authorize.Net on TinyVendor
Authorize.Net is a gateway, not a merchant account on its own, so this works well if you already have both.
1. Get your API credentials
Log in to your Authorize.Net account, go to Account > Security Settings > API Credentials & Keys, and generate or copy your API login ID and transaction key.
2. Add Authorize.Net as a gateway in TinyVendor
In your TinyVendor payment settings, choose Authorize.Net and paste in the API login ID and transaction key. No server, no webhook configuration to wire up yourself.
3. Create a sell link
Add a title, description, and price, and select Authorize.Net as the payment option.
4. Share it
Send the link directly, or drop it anywhere you'd normally post a link — a phone is all you need. There's no hosted checkout page to build yourself.
5. Buyer pays, you get paid
The buyer enters card details on a TinyVendor-hosted checkout that talks to Authorize.Net directly. Card numbers never sit on your own servers, so you carry no PCI scope, and the charge settles into your existing merchant account exactly as if you'd built the integration yourself.
6. Track it
The order appears in your TinyVendor dashboard the moment Authorize.Net confirms the transaction, right next to your existing Authorize.Net transaction reporting.
Questions
What does TinyVendor charge on top of Authorize.Net's fees?
2% of a sale on the Basic plan, 1% on Pro and 0.5% on Max, with no monthly fee and nothing to pay in a month with no sales. Authorize.Net and your merchant account bill you separately, at the rates in your own agreement.
How do I get an Authorize.Net account?
You apply directly through Authorize.Net's signup process, providing your business, banking, and tax details. If you already have a merchant account elsewhere, you can apply for the gateway-only plan and connect it to that account.
What Authorize.Net credentials does TinyVendor need?
TinyVendor needs your Authorize.Net API login ID and transaction key, both found in your Authorize.Net account's security settings.
Do I need a developer to connect Authorize.Net to TinyVendor?
No. You paste your API login ID and transaction key into TinyVendor's payment settings, and TinyVendor handles the connection — no code required.
