#### 2. The user did not receive the purchased item after payment

Please provide the following information to our TS team for transaction checking:

* Transaction Date/Time
* User ID
* Amount
* Coda Transaction ID
* Screenshot of payment proof from Coda

***

#### 3. Didn't receive a callback notification?

Please verify whether the configuration is complete and accurate under the `Integration -> Codapay -> Merchant & URLs Configuration` section on the Publisher Portal's left sidebar.

If everything is correct, please reach out to your Codapay support team with the Coda Transaction ID for further assistance.

***

#### 4. How does Codapay notify us of discontinued payment methods? Will we receive an error code if we request payment for a discontinued method?

Codapay will send notifications about discontinued payment methods to a subscription email address. If you request payment for a discontinued method, you will receive the error code 1301 Payment channel close/maintenance.

Refer to our Error Codes [here](https://coda-payments.gitbook.io/coda-private-technical-documentation/wVhQbDbPyotRr4wm96SR/codapay/codapay-appendix/common-error-codes).

***

#### 5. Brazil transactions face high-frequency errors in codes 248, 249, and 250

This is due to the KYC process implemented for verifying customer document numbers and validity, which includes validating the CPF/CNPJ number.

When a user makes a purchase, they are required to provide their CPF/CNPJ on the Coda checkout page. If customers input an invalid CPF/ CNPJ number, they will receive the following error message: “Invalid CPF/CNPJ, please verify your CPF/CNPJ number."

Refer to our Error Codes [here](https://coda-payments.gitbook.io/coda-private-technical-documentation/wVhQbDbPyotRr4wm96SR/codapay/codapay-appendix/common-error-codes).

#### 6. How can I differentiate Sandbox and Production transactions?

You can choose the appropriate options below:

* Merchant order ID, Example: Prod1234, Stage1234
* Configure sandbox and production URLs separately
