Linx API: What Exists and How to Use It with AI Agents
Linx, a Brazilian company owned by StoneCo, makes several retail systems, such as ERP, point of sale and e-commerce, and each product has its own APIs or web services. Access is granted to customers and partners according to the product they bought, and there is no single API for all of them. Store chains, franchises and retailers use it.
What the Linx API offers
Sales
Sales data from stores and channels, depending on the product.
Products and prices
Product records, size grids and price tables.
Stock
Balances per store and distribution center.
Customers
Customer records and purchase history.
Finance
Financial information exposed by the ERP, when available.

- For partners and customersCredentials and the type of authentication vary by Linx product and are provided to the customer or partner. The details are confirmed in the diagnosis.
- Each Linx product has its own rules and limits.
- Some access depends on commercial approval: plan ahead.
- Customer data is subject to Brazil's LGPD data-protection law and to contact consent.
What an iTeam agent does with the Linx API
Daily sales per store
The regional manager asks on WhatsApp how the stores are doing and the agent answers with the day's sales and targets.
Transfers between stores
The agent spots products sitting idle in one store and out of stock in another, and suggests a transfer to the stock team.
Customers with a recent purchase
The agent uses purchase history to tell customers when products they like arrive, within their consent.
Price mismatches
The agent compares ERP prices with the e-commerce site and lists mismatches for correction.
From the credential to the agent at work, with approval
Identify the product and the access

Credentials in the vault
The credentials supplied by Linx or the partner stay in the iTeam vault, and the agent is limited to reading at first.
Test with one store
Validate the data with a pilot store before extending it to the chain.

Questions about the Linx API
Is the Linx API free?
It depends on the product and the contract. API access is granted according to what was purchased and may involve commercial terms.
Do I need to write code to use the Linx API with iTeam?
Not necessarily. iTeam's HTTP tool learns the endpoints from the documentation you provide, and the deployment team sets it up.
Does it work with any Linx system?
It depends on whether the product you use offers an API or web service. This is assessed in the diagnosis.
