Separate the commercial and technical dependencies
Ask the relevant parties to confirm the permitted environment, account arrangement, available endpoints, authentication method and operational contacts. Record whether prices, execution or both are supplied. The integration project should not infer entitlements from a product catalogue or a test login.
The brokerage owns its provider selection and trading policy. A technology engagement can scope connectivity, mapping, monitoring and reconciliation around those decisions without claiming to supply a liquidity relationship itself.
Prepare a connection register
| Record | Purpose |
|---|---|
| Provider and environment | Distinguish test and production arrangements |
| Data and instruction scope | Identify supported markets, symbols and permitted actions |
| Identity and access owner | Assign credential issue, storage, rotation and revocation |
| Operating contacts | Name the route for rejection, interruption and reconciliation issues |
| Change notice | Agree how endpoint, certificate or specification changes reach operators |
Request approval for the validation plan from the parties that operate the systems. A test must exercise the intended workflow without assuming unrestricted access to production services.
Validate ownership during a failure
Illustrative connection review: pricing continues while an execution channel is unavailable. The operator must be able to distinguish the two conditions and follow the approved response. A single green “connected” indicator is not enough to explain the complete service state.
Capture normal-state evidence, a controlled failure case and the reconciliation or recovery steps. Review responsibility at every handoff before acceptance. The resulting register supports later changes such as an additional provider, a replacement endpoint or a platform transition.
