Technical Aspects

Security Considerations

• All API requests must be made over HTTPS. Calls made over plain HTTP will fail.

• API requests without Payload-signature will also fail.

• You will be able to hit our APIs only from the IPs you have previously whitelisted on the Merchant Panel.

Endpoint domains

Each environment has its own domain. The path of the endpoints do not change.

Environment	Domain
Staging	https://api-stg.tupayonline.com/
Production	Provided once you complete the testing

Notes:

• You will use the STG endpoints to integrate.

• The STG and PROD environments are not communicated in any way.

• No transaction created on the STG environment will be reflected on the PROD environment or vice versa.

• The API Keys and configurations between environments are also different.

• In case of seeing the error "Insufficient Funds" on STG, you can create and approve a deposit or reach out to [e-mail] to add funds to your account.

IP Whitelisting

For security purposes, you need to whitelist the IPs from where you will call our API.

In order to whitelist your IPs and make the process as smoother as possible, you should go to Settings -> API Access and add the list of IPs you will possibly use under the Cashouts IP Address section.

We convert all the data we receive to UTF-8. Make sure you are also converting it into UTF-8 to make sure both parties have the same details.
