The payment arrives and the order never hears
In a Colombian store the customer pays through a link and someone marks the order as paid in a chat. If the link is used twice, or the bank is slow, the warehouse ships too much or does not ship. Integrating a payment gateway removes that message: the gateway tells the system and the order changes state when the payment is confirmed.
Wompi and Mercado Pago are not the same contract. Each has its key, its notice and its state. Copying a button without storing the order reference mixes charges. Integrating the Mercado Pago API, or Wompi, means writing which order is charged, which amount and what happens if the payment stays pending.
Payment notice, order and a clear state
We connect the gateway to the order system. The customer pays in the Wompi or Mercado Pago flow. The notice returns to your application and is stored: approved, pending or rejected. The amount comes from the order. Fees are defined by the gateway, not by this page.
This page is not the method you use to pay us. Krats.tech can receive its milestones through Mercado Pago, PayPal, Wise, bank transfer or USDT; that lives on the payments page. The work here is different: put the API inside your store or your panel. We do not publish a case named Wompi. The first version of a charge against an order starts at €500 and is credited if the project continues. If there are also users, inventory and rules, the web application starts at €4,500.
What you get
- The charge flow: order, amount, return and the states you will use.
- A connection to Wompi or the Mercado Pago API, with the keys in your account.
- A record of the payment notice and of the order it belongs to.
- Code in your name and thirty days to correct the delivery.
The test uses the gateway sandbox, with a test payment, before production. Production keys stay in your account, not in a loose file in the chat.
Reference price
The first version of a charge tied to an order starts at €500. A web application that also runs inventory or users starts at €4,500. Support: €150 a month, with no lock-in. Amounts in EUR. Our milestones are paid near 40, 30 and 30 percent. The Wompi or Mercado Pago fee is charged by that gateway, not by the studio.
Which case is actually published
There is no public case of a Wompi integration or of the Mercado Pago API inside a client's store. We do not invent one. The platform of La Bodega de Nacho, MaxiOferta and MyTienda shows an order that exists once, with inventory per brand. Tying the charge to that kind of order is the same kind of work, and it is quoted when the gateway enters the scope.
A gateway is one more API. The wider frame is systems and API integration.
Questions about payment gateways
Do you integrate Wompi?
Yes, as a gateway inside your order or your store, with the payment notice stored. You need your Wompi account and the keys. We do not open the account for you and we do not publish a Wompi fee: Wompi defines that.
Does the Mercado Pago API change the project price?
No. The development price stays in euros: €500 for the first version of one flow, or from €4,500 if it is already an application. Mercado Pago moves the buyer's money. Its fee is not a second Krats.tech price list.
Can I pay you with Mercado Pago and also integrate it in my store?
Those are two jobs. Paying a project milestone through Mercado Pago is on the payments page. Integrating the API so your customers pay inside your system is this engagement, with its own scope.
How do I start the gateway integration?
Through the form or krats.tech@gmail.com. If you prefer WhatsApp, say so in the message. Tell us whether the order already exists in a system and whether the gateway is Wompi, Mercado Pago or another.
I want the payment tied to the order
Tell us how you charge today and which system holds the order. We see whether it fits a €500 first version. The contact form; WhatsApp if you ask for it in the message.
