SideCar microservice

Synchronous, real-time webhook proxy for FileMaker Server.

Webhook Direct is a cloud-native microservice that lets FileMaker Server receive webhooks from external applications in real time - with immediate confirmation back to the caller of whether your FileMaker script succeeded or failed. Use it whenever the calling service needs a synchronous answer, not a fire-and-forget acknowledgment.

What it is

A synchronous proxy in front of FileMaker Server.

Webhook Direct accepts incoming HTTP requests, forwards them immediately to FileMaker Server, waits for your script to complete, and returns the result to the caller in the same HTTP transaction. JSON and HTTP form data are both supported, with optional basic authentication.

Important: no built-in queueing or retry

Webhook Direct is intentionally synchronous. It does not queue messages and does not retry failed deliveries - if FileMaker Server is unavailable, the caller gets the failure immediately and can retry on its own schedule. If you need fault-tolerant queueing with up to 14-day retry, use the Webhook Notifier instead.

Key capabilities

Real-time, authenticated, production-ready.

Webhook Direct is built specifically for synchronous integration patterns where the caller needs an immediate, authoritative response.

Real-time webhook proxy

Webhook Direct is a synchronous proxy: when an external service POSTs to it, the request is forwarded immediately to FileMaker Server, the script runs, and the result is returned to the caller in the same request.

Immediate success/failure confirmation

The calling service gets an immediate response indicating whether your FileMaker script succeeded or failed - not just that the webhook was queued for later processing.

JSON and HTTP form data

Accepts JSON payloads and HTTP form data. Use whichever your calling service emits.

Basic authentication

Supports basic access authentication so you can enforce a credential on every incoming request, keeping the endpoint locked to authorized callers only.

Industrial-strength endpoint

Built on the same AWS infrastructure that powers the rest of Soliant.cloud - high availability, monitored, and engineered for production traffic.

Designed for synchronous integrations

When a third-party service won’t complete its workflow until your endpoint confirms success, Webhook Direct is the SideCar to put in front of FileMaker Server.

Choosing the right SideCar

Webhook Direct or Webhook Notifier?

The two webhook SideCars solve different problems. Pick the one that matches the calling service’s expectations.

Use Webhook Direct when…

The calling service needs immediate, real-time confirmation that your FileMaker script succeeded or failed. Examples: payment authorization callbacks, two-step verification flows, integrations that won’t complete without a synchronous response.

Use Webhook Notifier when…

The calling service is fire-and-forget - it just wants to deliver the message and doesn’t need a confirmation that your FileMaker logic succeeded. Examples: order notifications, audit log pushes, content sync updates.
