Changelog

[1.0.11] - 2026-10-23​

Added​

  • Signed request authentication. Generate an Ed25519 keypair offline, then sign each request and send the x-sideshift-key, x-sideshift-timestamp and x-sideshift-signature headers instead of x-sideshift-secret. See Authentication.
  • POST /v2/create-account accepts an optional pubKey in the request body. The key is registered as the account's credential, and the response returns id and pubKey instead of secret.
  • New GET /v2/account/auth-keys, POST /v2/account/auth-keys and DELETE /v2/account/auth-keys/{id} endpoints to list, add and disable auth keys. Rotating a key no longer requires creating a new account.
  • New INVALID_SIGNATURE error code (401) for signature authentication failures.

Changed​

  • The x-sideshift-secret header is now the legacy authentication method. It works during a migration period. Existing integrations should register a key and switch to signed requests. See Migrate to Signed Requests.

[1.0.10] - 2026-08-26​

Added​

  • Introduced depositVariableOnly and settleVariableOnly on the /v2/coins endpoint. These fields list networks that only support variable rate shifts as a deposit or settle, using the same shape as fixedOnly: false when no network applies, otherwise an array of networks.

Deprecated​

  • Marked variableOnly as deprecated on the /v2/coins endpoint. It remains the union of depositVariableOnly and settleVariableOnly. Use the split fields instead so a network that is variable only on one side is not treated as variable only on both.

[1.0.9] - 2026-07-01​

Deprecated​

  • SideShift Pay and its checkout endpoints (POST /v2/checkout and GET /v2/checkout/{checkoutId}) are deprecated and their documentation has been removed. Existing integrations should migrate to the SideShift API shift endpoints directly.

[1.0.8] - 2026-04-09​

Added​

  • New POST /create-account endpoint to programmatically create a SideShift.ai account and receive the account id and secret.

[1.0.7] - 2026-04-03​

Deprecated​

  • Legacy Widget Embed is deprecated. New integrations should use the SideShift API directly. Existing widget embeds remain operational, but the embed generator is no longer available.

Migration Path​

  1. Generate quotes and orders via the SideShift API.
  2. Build your own integration UI and event tracking on top of API responses.
  3. Use the integrations page for reference implementation patterns.

[1.0.6] - 2026-03-31​

Added​

  • Added checkoutId to SideShift Pay webhook payloads so webhook events can be correlated directly to the originating checkout.

[1.0.5] - 2026-01-20​

Added​

  • Documented error codes in v2 error responses and troubleshooting.

[1.0.4] - 2025-08-14​

Added​

  • Added optional commissionRate parameter to /v2/pair and /v2/pairs endpoints with 0% to 2% range support.

[1.0.3] - 2025-06-11​

Added​

  • New /v2/cancel-order endpoint to cancel an existing order by expiring it.

[1.0.2] - 2025-05-20​

Added​

  • Required affiliateId and x-sideshift-secret parameters for /pair and /pairs endpoints.

[1.0.1] - 2025-02-24​

Added​

  • Introduced networksWithMemo in the /v2/coins endpoint.

Deprecated​

  • Marked hasMemo as deprecated in the /v2/coins endpoint.
