Appointment/PO Validation for Dock Appointments Without the IT Project

Key Takeaways

• PO validation now works without a webhook build — no IT project required.
• Email a CSV of valid POs and Opendock blocks invalid bookings automatically.
• The webhook path still exists; the CSV path is an alternative, not a replacement.
• Validated rules today include PO number, warehouse match, and date range.

Your warehouse receives by purchase order. Every appointment should tie to a real PO — the right order, the right warehouse, the right date window.

When a carrier books against a PO that does not exist, or schedules at the wrong facility, or shows up outside the valid date range, someone on your team has to catch it. That means manual appointment reviews, ghost appointments that waste dock time, and freight that shows up without a valid order behind it.

Opendock already solves this with PO validation. The problem has never been the capability — it has been the setup. Until now, PO validation required building and hosting a webhook endpoint on the customer side.

For warehouses without available development resources, or for teams that want to test Opendock before committing to a full integration, that requirement has been the blocker.

Now, PO validation works without building anything. You email a CSV of valid POs to a warehouse-specific address. Opendock's integration engine handles the rest — parsing your list, storing it, and checking every booking against it automatically. No webhook to build. No IT project. No engineering resources required.

Why Has PO Validation Been Hard to Get Started With?

PO validation has been hard to get started with because it required the customer to build and host a validation endpoint themselves. The existing webhook-based approach works well once it's running: when a carrier tries to book an appointment, Opendock calls the customer's endpoint, the endpoint checks whether the PO is valid, and the result either confirms or blocks the booking.

But getting to that point requires the customer to build and host that endpoint themselves. For large operations with dedicated development teams, that is a manageable project. For everyone else, it is a delay — sometimes a long one. IT teams are allocated elsewhere, and dev resources are prioritized against other projects.

The other scenario is pilots. A warehouse evaluating Opendock often wants to see real validation working against real data before committing to a full integration. The webhook requirement makes that difficult.

The CSV-based workflow solves both problems by handling the endpoint on Opendock's side. The customer's only responsibility is keeping the PO list current.

How Does It Work?

Setup happens entirely on Opendock's side. We create a dedicated email address for your facility and configure the validation rules. Your team does not set up or configure anything.

From there, the process is three steps:

1. You send your PO list. Export your valid POs from your WMS or ERP as a CSV using the Opendock template, and email it to your facility's address. You choose the cadence — daily, weekly, or triggered by your own systems.
2. Opendock stores and applies your list. The file is parsed and your valid PO list is updated automatically.
3. Bookings get validated in real time. When a carrier enters a PO number to schedule an appointment, Opendock checks it against your list. Valid PO? The appointment is confirmed. Invalid PO? The booking is blocked and the carrier sees an error message.

The carrier booking experience is identical to what they would see with any other PO validation setup — they do not know or care how the validation is powered on the backend.

What Gets Validated

The rules are configurable per customer. The current validated rules are PO reference number matching, warehouse matching, and date range validation. The PO entered at booking must exist in your list, must be for the correct warehouse, and the appointment date must fall within the valid window for that PO.

Additional rules are being added as more customers onboard. Carrier validation — ensuring the correct carrier is the one scheduling — has been identified as a common next requirement and is on the roadmap.

Who This Is For

Warehouses that receive by PO and deal with ghost appointments. PO validation blocks bookings against orders that don't exist before they get confirmed.

Operations teams that want validation without involving IT. If you can export a CSV from your WMS and send an email, you can run PO validation.

Teams evaluating Opendock before a full integration. You can start with real PO validation running against real data from day one.

Existing customers whose webhook integration has been delayed. The CSV workflow gets you to the same outcome while that project works its way up the queue.

Stop Reviewing Every Appointment Manually

Ghost appointments and wrong-PO bookings are a solvable gate workflow problem. You do not need an IT project or a six-month integration timeline to start blocking them.

Frequently Asked Questions

Does My IT Team Need to Be Involved?

No. The two setup steps are handled entirely by Opendock. The only action your team takes is emailing a CSV of valid POs to the warehouse alias.

Is This a Replacement for the Webhook Path?

No. Both options exist and are available to customers. The CSV workflow is an alternative for customers who cannot or do not want to build a webhook endpoint.

Is There an Additional Cost?

PO validation via CSV is included in Opendock at no additional cost. It is not an add-on or a separate tier. If you are already on Opendock, you have access to it.
