Build on Wijha

Connect your store to external systems with signed webhooks and a public REST API. Create keys and endpoints in the Merchant Portal under Store settings → Developers.

Where everything lives

Open Merchant Portal → Store settings → Developers. From there you manage:

  • API keys — create keys with scopes for the public REST API (prefix wjh_).
  • Webhooks — register HTTPS endpoints, choose events, and optionally set a signing secret.

Webhooks and /api/v1 REST are both live. Use the guides below for events and REST examples.

Guides in this site

  • Webhooks — events, retries, HMAC signatures, and enriched delivery JSON.
  • Public API — authentication, scopes, rate limits, and request/response examples.

API key format

Merchant API keys are generated as wjh_ followed by a high-entropy secret. Store the raw key once at creation — Wijha only keeps a hash and a short prefix for display.
