API Compatibility

We consider the following changes as non-breaking changes to the API:

• Adding a field to an object
• Introducing a new API endpoint that did not exist before
• Adding a query parameter
• Adding a new payment method (each Payment has a payment_method field)
• Adding a new currency

However, we consider these examples as breaking changes:

• Changing the datatype of a field
• Removing a field from an object
• Changing the semantics of an existing field
• Changing URLs
