Broker API Integration Checklist for Trading Software Projects
What to confirm before building a broker API integration: access, authentication, orders, data, test environments, limits, retries, logs, and acceptance checks.

This checklist is for teams preparing an application that needs to read account data, receive updates, or submit client-defined order instructions through a broker API.
Confirm API eligibility and ownership
Identify the account owner, API product, available documentation, support channel, and any approval needed to use the API. A public website feature list is not proof that the required endpoint is available to a particular account.
Document authentication and permissions
Record how credentials are issued, stored, rotated, and limited. Apply only the permissions the software needs, and identify who can revoke access if an incident or handoff requires it.
List the required data and actions
Specify market, account, order, and position data as well as required order types and cancellation paths. Note whether responses are synchronous, streamed, or later retrieved.
Ask about test environments
Confirm whether a sandbox, demo account, or documented test procedure exists. If it does not, define a controlled acceptance approach before using a production account.
Plan for limits and ambiguous responses
Rate limits, timeouts, retries, and duplicate prevention need explicit handling. A timeout is not evidence that an order did not reach the broker, so local state and later reconciliation matter.
Define logs and acceptance checks
Agree on the audit trail, alerts, test cases, failure behaviour, documentation, and ownership after launch. These items turn an API call into an integration that is ready to operate.
Agree on handoff before the connector is built
A finished connector needs more than successful requests in a development environment. Agree who owns credentials, where configuration is stored, which records an operator can review, how alerts are handled, and what information is needed when the broker interface changes.
This handoff identifies client-controlled decisions such as account permissions, enablement of a live workflow, alert recipients, and the person responsible for operations. Clear ownership makes an integration easier to maintain without implying that it removes venue or market uncertainty.
- Credential and configuration owner
- Order-state and reconciliation record
- Alert routing and response owner
- Change process for API updates
Common questions
What access is needed before development starts?
The team normally needs documentation, approved development or test access where available, an understanding of permissions, and a secure process for credentials.
Why separate test and production environments?
Separate environments make it easier to verify changes without confusing test records, credentials, or configurations with the client-controlled production workflow.
