What are the required parameters for the collection API?

The collection API requires the following parameters:
  • method - The collection method (e.g., "card", "bank_transfer")
  • amount - The total amount including all applicable fees
  • customer_id - The unique identifier created via the Customer API
  • wallet_id - Your business wallet ID for the specific currency
  • phone_number - Required for certain collection methods
Always consult the API documentation for the specific requirements of each collection method, as they may vary.

​
Do we need to implement all collection methods?

No, you only need to implement the collection methods that correspond to your supported currencies. For example:
  • If your business only handles CAD and NGN transactions, you don’t need to implement the Open Banking flow used for EUR/GBP transactions
  • You can choose to implement only the specific collection methods that align with your business needs and supported currencies

What is IP whitelisting and why is it required?

IP whitelisting is a security requirement where merchants must submit their server IP addresses during onboarding. Only API requests from whitelisted IP addresses will be accepted—requests from non-whitelisted IPs will be rejected. To whitelist your IP addresses:
  1. Identify all IP addresses that will make API calls
  2. Submit them to [email protected] during onboarding
  3. Contact support if you need to add or update IPs after onboarding
For more details, see the IP whitelisting guide.
