# Upcoming Breaking API Change - 4/16/2026

## The changes will be effective starting 4/16/2026 at 7:00 PM (PST) in production.

The changes will be available for testing in sandbox starting 4/2/2026 at 7:00 PM (PST).

### Deprecation of the creation of transfers with type FEE

#### What’s Changing?

On April 16, 2026, Fees will only be created via the `Fees` resource and will no longer be generated as `Transfers` resources that are retrievable from the /transfers endpoint. In other words, Transfer resources of type FEE will no longer be created. More details below:

- All existing Transfers of type FEE have now been copied to the `Fees` resource.
- If you would like to map between Transfers and Fees, a Transfer of type FEE will have a `link` to the fee with the ID of the `Fees` resource.
- Existing Transfer resources of type FEE will remain accessible, i.e., no resources will be deleted.
- The fee `link` on a parent Transfer will now direct to the fee resource on /fees instead of /transfers.

#### What action is needed?

Clients who currently retrieve fees from the /transfers endpoint or rely on webhooks must transition to utilizing the /fees endpoint.

**Example of Fetching Fees for a Transfer:**

To fetch Fees for a given transfer use the following `linked_to` query parameter on /fees.

#### Why are we making these changes?

This modification aims to provide a clearer distinction between money movement and fees, thereby simplifying API comprehension. Furthermore, it will reduce the number of webhooks triggered for implementations that subscribe to transfer webhooks.

#### What You Need to Do

- **Review Your Integration:** Ensure your application is compatible with the new API behavior.
- **Make Necessary Updates:** Modify your implementation accordingly before the change takes effect.
- **Test in Sandbox:** Transfers of type FEE will stop being created in sandbox starting **4/2/2026 at 7:00 PM (PST)**.
