Deprecation of Trailing Slashes in URLs
Today we are announcing the deprecation of support for API requests that include a trailing slash at the end of the URL. While our documentation has never endorsed this pattern, we identified a small number of clients still relying on it. To ensure a smooth transition, a 2-month grace period will apply before the behavior is fully removed.
Details
- Requests using URLs that end with
/(e.g.,/v0.1/checkouts/) will continue to work during the grace period. - After the grace period ends, these requests will return an error.
- Standard, documented URLs without trailing slashes (e.g.,
/v0.1/checkouts) remain fully supported.
Timeline
- Deprecation announcement: 17.11.2025
- Grace period: 2 months
- Removal date: 17.01.2026
Required Action
Please consult the API documentation and update any API calls that include a trailing slash.
This change typically only requires removing the final / in affected endpoints.
If you run into issues or need help identifying affected requests, please contact our support team.
