Prop Firm Software API & Webhook Checklist
An API checkbox says almost nothing about integration quality. Engineering buyers should inspect which resources can be read/written, how events are delivered and how the system recovers when either side fails.
Authentication
- Key/token model.
- Scope/permissions.
- Rotation/revocation.
- Environment separation.
Resource coverage
List required objects: customer, order, challenge, account, trade/event, risk state, KYC, payout, affiliate and product configuration. Mark read/write/event support separately.
Webhook events
FXPropTech's current public webhook material illustrates the level of specificity buyers should seek, listing events such as trade opened/closed, account status change, drawdown breach, payout processed, challenge passed and KYC verified. Confirm which events are actually available in your purchased scope.
Delivery reliability
- Signed payloads.
- Unique event ID.
- Retry schedule.
- Maximum retry period.
- Duplicate delivery behavior.
- Ordering guarantees or lack thereof.
- Replay/backfill capability.
Write safety
For account creation, payouts or other writes, ask about idempotency keys and duplicate-request behavior. Network retries should not create duplicate financial/operational actions.
Rate limits
Record per-second/minute/day limits, burst behavior, response headers and enterprise increase process. Model peak jobs such as bulk migrations and reporting.
Sandbox
A useful sandbox should allow realistic lifecycle and failure tests without production accounts. Verify whether trading-platform and KYC/payment dependencies can also be simulated.
Versioning
Ask how breaking changes are announced, deprecation windows, version pinning and changelog access. Integration maintenance is part of long-term TCO.
Observability
Engineering teams need request IDs, useful errors, delivery logs and enough support context to debug a failed event without exchanging screenshots.
Plan gating
Tradaxi's current public tiers, for example, place webhook event API on Pro and custom API integrations on Enterprise. Always map API requirements to the exact commercial tier.

FAQ
Are webhooks real-time?
They can be near-real-time event delivery, but buyers should verify actual delivery behavior, retries and dependencies rather than assume zero latency.
Do I need an API if the vendor has integrations?
Not necessarily. Native integrations may be sufficient for standardized operations; APIs matter more when you need proprietary workflows or external systems.
