Highway - Secure Rate Confirmation

Setup

To use Secure Rate Confirmations:

The broker must have an active Highway integration
The integration must have a source setting called secureRateCON, and the value must equal True.

If SRC is not enabled, carrier confirmations will continue to be delivered via standard email attachments.

Setting Up SRC Configuration in Tai

Complete the following steps to configure SRCD in Tai:

1. Create a New User in Tai

Navigate to LSP → Users → Add New User and create a user with the following details:

Name: Highway SRC
Login: integrations{company_name}@gohighway.com
Email: integrations{company_name}@gohighway.com
Password: Any password of your choosing
Organization: Match the Owner Organization configured in Load Lock
Permissions: User Allowed Org Access

2. Generate a Public API Authentication Key

Navigate to LSP → Public Authentication Keys → Add Public Authentication Key. Complete the following fields:

Organization: Select the appropriate LSP organization
Staff User: Select the Highway SRC user created in the previous step

Click Save. A new authentication key will be generated automatically and displayed in the Authentication Key column.

3. Provide the Authentication Key to Highway

Send the generated authentication key to your Highway contact or load-solutions-team@gohighway.com. Once Highway has configured the authentication key within their system, SRC webhook updates, including signed rate confirmation PDFs, will begin flowing into Tai shortly thereafter.

Workflows

How to send a Secure Rate Confirmation manually

Where to go: Shipment Details → Send Message.

1. A broker opens a shipment and selects Send Message.
2. If a Carrier Confirmation is included and the broker has Highway SRC enabled:
  - The system prompts the broker to send the document via Highway Secure Rate Confirmation.
  - The Secure Rate Con button appears under this specific workflow.
  - Through this feature, the broker should not add the carrier email manually, because the rate confirmation is sent directly to Highway via API.
    
    Follow these steps:
    1. Send Message
    2. Add Template > Carrier Confirmation
    3. Click the Secure Rate Con button
    If the broker wants to send the rate confirmation using the traditional email workflow instead of Highway SRC:
    1. Send Message
    2. Add Carrier Email
    3. Select carrier confirmation template
    4. Send Email
1. The broker clicks Highway SRC to send.
2. The TMS sends the rate confirmation to Highway’s Secure Rate Confirmation service.
3. Highway delivers a secure link to the carrier.
4. The carrier must authenticate (2FA) before viewing the document.
5. The carrier can accept or reject the rate confirmation.
6. The TMS receives status updates from Highway and records them on the shipment.
7. When accepted, the signed rate confirmation is automatically downloaded and stored in the shipment documents.

How SRC is sent automatically on a Book It Now booking

Where to go: No action needed in the TMS — this happens automatically when a carrier books a load through Highway Book It Now.

When a carrier books an eligible load through Book It Now, the TMS sends the Secure Rate Confirmation to Highway on its own, using the same SRC path as the manual button.
SRC is sent automatically only when the load qualifies: your brokerage has the Highway integration with SecureRateCon enabled, the load owner's email is configured on the integration source, and the carrier has a Highway Carrier ID in its broker carrier parameters.
If any of those are missing, or if Highway can't accept the SRC, the TMS automatically falls back to the standard carrier-confirmation email — the carrier still gets a rate confirmation.

How to send an SRC from a workflow (Send Secure Rate Confirmation action)

Where to go: Back Office → LSP → Workflow Automation

Open or create a workflow
Add a step → Actions → Send Secure Rate Confirmation.
Add the Send Secure Rate Confirmation action to any workflow where you want the SRC to go out automatically. The action shows an envelope icon.
There is nothing to configure — the action has no extra fields. Because the confirmation goes directly to Highway by API, you do not add a carrier email address.
The step reads "Execute Send Secure Rate Confirmation Action with Highway" in the workflow builder.
The action only appears when the broker that owns the workflow has the Highway integration with Secure Rate Confirmations enabled. If you don't see it, SRC isn't enabled for that brokerage.
Rate Confirmation Status Updates
The TMS records important activity updates from Highway and logs them on the shipment.
Viewed
The carrier has opened the rate confirmation.
Activity Log: “The Secure Rate Confirmation sent through Highway has been viewed by the carrier.”
No shipment status change
Accepted
The carrier accepted the rate confirmation.
Activity Log: “The Secure Rate Confirmation sent through Highway has been accepted by the carrier.”
Once accepted:
The signed rate confirmation is automatically downloaded
The document is attached to the shipment
Document type: Carrier Confirmation
Visibility: Private
Shipment Status advances to Dispatched for Truckload, or Ready for all other shipment types
Note: Accepting a Secure Rate Confirmation through Highway does not populate driver, truck, or trailer information on the shipment. The acceptance webhook provided by Highway includes the acceptance status, activity history, timestamps, and the signed Rate Confirmation document, but it does not include equipment or driver details. If collecting driver, truck, and trailer information is required as part of the confirmation process, use the standard Rate Confirmation workflow instead.
Rejected
The carrier rejected the rate confirmation.
Shipment status moves to Sent
Activity Log: “The Secure Rate Confirmation sent through Highway has been rejected by the carrier. Please follow up with the carrier directly for next steps.”
No shipment status change
Cancelled / Not Delivered
If the document could not be delivered to the carrier.
Activity Log: “The Secure Rate Confirmation sent through Highway was not delivered to the carrier.”
No shipment status change
Supported Carrier Confirmation Types

Secure Rate Confirmation supports all carrier confirmation document types generated by the TMS.

Any carrier confirmation attached to the Send Message modal can be delivered through the Highway SRC workflow.
What the Carrier Sees
1. Email Notification
When a broker sends a rate confirmation, the carrier receives an email from Highway (hello@highway.com) notifying them that a new rate confirmation has been issued. The email identifies the broker by name and includes a "View Rate Confirmation" button to securely access the document.
2. Account Setup (New Carriers)
First-time carriers are taken to a Highway onboarding page. The platform highlights key benefits, fast profile creation, no repeated data entry, portability across brokers, identity security, and no cost, before prompting them to Get Started or Log In.
3. Carrier Lookup
The carrier enters their DOT or MC number to find their company. Once their carrier profile is confirmed (showing company name, DOT#, and MC#), they click Continue.
4. Identity Verification
The carrier enters their email address to verify their identity before accessing the rate confirmation.
5. Rate Confirmations Dashboard
After logging in, carriers land on the Highway platform and can navigate to Rate Cons in the top menu. The dashboard displays all rate confirmations organized by status: New, Viewed, Accepted, Cancelled, Rejected, and All.
6. Viewing & Acting on a Rate Confirmation
Opening a rate confirmation displays the attached PDF document alongside a view history log showing each time the document was accessed. The carrier has two options:
Accept Terms — to formally accept the rate confirmation
Reject — to decline it
Once accepted, the status updates to Accepted and the carrier can Download PDF for their records. The "Reject/Accept Terms" buttons are replaced by the download option.
Frequently asked questions
Do I still have to click "Highway SRC" if the load books through Book It Now?
No. When an eligible load books through Book It Now, the SRC is sent automatically. The manual Send Message → Highway SRC path is still available for confirmations you send by hand.
Why did the carrier get a normal email instead of a Highway secure link?
The SRC couldn't be sent, so the TMS fell back to the standard carrier-confirmation email. Common reasons: SecureRateCon isn't enabled, the carrier has no Highway Carrier ID, the integration source is missing the load-owner email, or Highway returned an error. The carrier still receives a valid rate confirmation.
Why did my shipment jump to Dispatched by itself?
The carrier accepted the Secure Rate Confirmation. An accepted SRC advances the status to Dispatched (Truckload) or Ready (other types), mirroring the carrier confirmation portal. It will never move the status backward.
The Send Secure Rate Confirmation action isn't in my Workflow Automation list — why?
The action only appears for brokerages with the Highway integration and Secure Rate Confirmations enabled. If it's missing, SRC isn't enabled for that broker.
If something doesn't work
Carrier got an email instead of a secure link: confirm SecureRateCon is enabled, the carrier has a Highway Carrier ID, and the load has an owner. The email fallback means the confirmation was still delivered.
Shipment status didn't change after the carrier accepted: check that the shipment wasn't already past Dispatched — status only moves forward. The acceptance is still recorded in the Activity Log.
Still stuck: contact Tai Support with the shipment ID and roughly when the carrier responded.
