Getnet API: what you can do and how to use it with AI agents
Getnet, a Brazilian payment acquirer, offers online payment APIs for registered merchants, with cards, Pix (Brazil's instant payment system), boleto (a Brazilian bank payment slip), recurring billing and transaction lookup. E-commerce sites, platforms and companies that already use Getnet as their acquirer rely on it. Access requires the merchant account's credentials and a sandbox environment.
What the Getnet API offers
Card payments
Authorize, capture and cancel credit and debit transactions.
Pix and boleto
Generate Pix charges and boletos and check whether they were paid.
Recurring billing
Plans and subscriptions with automatic charging.
Tokenization
Secure storage of cards for future purchases.
Notifications
Alerts when a transaction changes status.
How to access the Getnet API
- With your company’s credentialsUses OAuth 2.0 with a client ID and client secret issued to the merchant account, plus the merchant's establishment identifier. Sandbox and production credentials are separate.
- Card data follows PCI DSS rules: the agent should never handle card numbers.
- Cancellations and refunds need approval and an amount ceiling.
- Always use the sandbox before production.

What an iTeam agent does with the Getnet API
Duplicate payment request
When the customer asks, the agent generates a new Pix or boleto for the same amount and sends it through the support channel.
Transaction reconciliation
The agent matches approved transactions to orders and flags pending captures or mismatched amounts.
Cancellation with approval
The agent finds the transaction, prepares the cancellation and runs it only after finance approves.
Overdue subscriptions
The agent identifies declined recurring charges and organizes the outreach to each customer.
From the credential to the agent at work, with approval
Request the credentials from Getnet
With your merchant registration active, get the client ID, client secret and establishment identifier for the sandbox.
Store it in the iTeam vault
Add the credentials to the vault, keeping lookups separate from actions that move money.
Test in the sandbox and keep approval
Validate in the sandbox and keep cancellations and refunds under human approval.

Cash flow forecast team
Every week the projection is rebuilt from your books, open invoices and bills, with a plain note on what changed and why.
Bookkeeping team
Transactions are categorized as they come in, receipts are matched, and the month-end close starts with a short list of questions.
Questions about the Getnet API
Is the Getnet API free?
Using the API is tied to your acquiring contract: you pay the agreed fees per transaction and product, not a charge for the API itself.
Do I need to write code to use the Getnet API with iTeam?
Not necessarily. Once you have the credentials, the iTeam deployment team configures the calls from Getnet's documentation.
Do I need to be a Getnet customer?
Yes. The payment APIs are for merchants registered with Getnet.
