Steps

  1. Server: generate signature = SHA1(sorted params + api_secret) with timestamp
  2. Browser: POST file + api_key + timestamp + signature to /v1_1/{cloud}/auto/upload
  3. Use upload presets for transformations/folder defaults
  4. Deliver via URL transformations (f_auto,q_auto,w_...) — never serve originals
