Automate DAT One with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• New loads on your lanes, before dispatch

  Build this

  Starts

  Every weekday at 6:00 in your time zone

  Step 1

  For each lane you name, search loads with your origin, destination, deadhead and equipment.

  Step 2

  Keep the loads that were not there on the last run.

  Step 3

  Keep the ones above your rate per mile and with days to pay under your limit.

  Step 4

  Email you the list, grouped by lane, with company, phone, rate and trip miles.

• Weekly lane rates for your quotes

  Build this

  Starts

  Every Monday at 7:00

  Step 1

  For each lane and equipment type you name, look up the lane rate in Quick Rate Lookup.

  Step 2

  Compare each average rate with the last run.

  Step 3

  Post the lanes, rates and changes to your TMS or spreadsheet webhook.

• Broker check on loads your system has picked

  Build this

  Starts

  When your system calls the workflow's webhook with a list of reference IDs

  Step 1

  For each reference ID, read the load's details.

  Step 2

  Keep the loads whose credit score or days to pay miss your limits.

  Step 3

  Post them, with company, MC#, credit score and days to pay, to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Search loads on a lane” would look like.

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

DAT One’s own options

DAT has a developer portal, developer.dat.com, that asks you to sign in before it shows anything, so what it offers and who may use it is not stated on DAT's public pages. DAT One itself is a monthly subscription, with carrier plans from $59 to $339 and broker plans from $159 to $449.

Signing in to DAT One

DAT One asks for your email address, then your password, then a verification step. Accounts that verify by email or SMS can upgrade to an authenticator app or security key through Make My Account Safer. With Fous you sign in once through DAT One's own sign-in with your own account: the login is sealed with AES-256, an emailed code is handled, and an expired session is signed back in.

Worth knowing

Include Deadhead changes Trip and Rate

With the Include Deadhead toggle on, origin deadhead miles are added to the Trip and Rate columns of your search results. Decide which view a method reads before you compare rates per mile across runs.

Credit Score and Days to pay come from Ansonia

The Credit Score and Days to pay in a load's details are Ansonia figures for the broker, not DAT's own. Market Rates with Spot Rate and Contract Rate appear only on plans that include them.

BOOK can leave DAT One

Selecting BOOK on a load may take you to the broker's own website to finish. A blank Commodity means you have to contact the broker, so keep booking with a person.

One search, many settings

A load search takes origin and DH-O, destination and DH-D, Full or Partial, equipment type, length, weight and a date range, and SEARCH BACK sets how old returned loads may be. Give each method these as inputs.
