Every Integrations route requires an API key that COP By issues to your integration.
Keep the key on your server. Partners must not put it in MiniPay. Never expose BRIDGE_API_KEY.

​
MiniPay first-party

The COP By miniapp calls /api/breb/* (same bodies as /api/integrations/breb/*) with no Bearer key. Those aliases pin integration_id to copby and require userAddress on list, get, and confirm so one wallet cannot read another. Use /api/integrations/breb/* from a partner backend. Use /api/breb/* from the miniapp.

​
Playground

  1. Open any endpoint in API reference.
  2. Paste the key in the Authorization field. You can omit the Bearer prefix; Mintlify adds it.
  3. Pick the Local server (http://localhost:3000) while pnpm --filter web dev is running.

​
Isolation

The key maps to one integration_id. List and confirm routes ignore any other integration id in the query or body. A payout created by partner A is not visible to partner B.
