This guide outlines the necessary changes to migrate from the deprecated *.onsleek.io API endpoints to the new *.onsleek.ai endpoints for cashback offers, coupons, promotions, and transactions. The migration primarily involves:
  • Changing the base API URL
    All requests should now use https://api.onsleek.ai/ instead of https://api.onsleek.io/.
  • Adding a /deals/ prefix to all endpoints
    Endpoints for cashback offers, coupons, promotions, and transactions are now grouped under the /v1/deals/ namespace.
    For example, /v1/cashback-offers/ becomes /v1/deals/cashback-offers/.
  • Switching activation ID from query parameter to path parameter
    Activation endpoints no longer use query parameters like ?couponId=abc123.
    Instead, IDs are passed directly in the path: /v1/deals/coupons/{id}/activate.
  • Preserving GET activation behavior
    GET activation endpoints still perform a 302 redirect to the affiliate URL.
    There is no change in behavior, only the URL format has changed.
  • Updating POST activation response structure
    POST activation endpoints still return the affiliate URL, but instead of a plain string,
    the response is now a JSON object:
    { "url": "https://affiliate.example.com" }
*.onsleek.io endpoints will be deprecatedAll https://api.onsleek.io/ endpoints will no longer be supported starting June 1, 2025.Please migrate to https://api.onsleek.ai/ and update your integrations accordingly before this date.

​
TL;DR

  • ✅ Update your base URL to https://api.onsleek.ai/
  • ✅ Use {id} in the path for activation endpoints instead of query parameters
  • ✅ All deal endpoints now live under /v1/deals/...
  • ✅ Activation behavior (POST + 302 redirect) remains the same
