Online payments with MercadoPago in your Sarah store
Last updated: 2026-04-07
Sarah integrates with MercadoPago to take payments in your online store. Customers can use card, bank transfer, and other methods MercadoPago offers in your region, depending on your account and checkout setup.
Setup in Sarah
- Log in to Sarah.
- Go to Settings > Integrations > MercadoPago.
- Fill in the fields the screen asks for (for example credentials or test/production mode).
Exact labels may vary by version. If MercadoPago asks you to create an application or copy keys from MercadoPago Developers, follow their official guide. Never share those keys by email, public chat, or social posts.
Payment notifications: you do not need to configure custom URLs or technical routes for Sarah. With the integration linked correctly, the store updates the online order status based on MercadoPago.
Customer journey (overview)
- The customer builds a cart and checks out.
- The MercadoPago payment flow opens (according to your setup).
- The customer pays or chooses a pending method (for example cash at an agency), if available.
- They return to your store or see a result message as appropriate.
- In Sarah, the order should show pending, paid, or not completed, matching what happened in MercadoPago.
If a payment stays pending (for example retail cash-in), crediting can take time; also check status in the MercadoPago app or dashboard before shipping.
What order status means for you
| What you see in Sarah | What it means |
|---|---|
| Awaiting payment | The customer has not finished or payment is not credited yet. |
| Paid | Payment is treated as confirmed for the online order. |
| Declined or incomplete | Payment did not complete; the customer may retry depending on checkout options. |
Exact wording may differ slightly in the UI.
Common payment options
MercadoPago may offer, depending on country and configuration:
- Credit or debit card
- Bank transfer or similar rails
- Cash networks where applicable
- MercadoPago wallet balance
- Installments and promotions per MercadoPago
The real list is defined by your account and checkout.
Best practices
- Production vs test: use MercadoPago’s sandbox only for testing; go live with production credentials as they document.
- Secrets: treat credentials like passwords; revoke or rotate them in MercadoPago if they were exposed.
- Before fulfilling: for pending payments, confirm money in MercadoPago first.
- Amounts: keep store prices and shipping aligned with what the customer is charged.
