Automate Fieldglass 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 job postings in your inbox before 8:00

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  Get the job postings waiting for a response in Work Items.

  Step 2

  Keep the job postings that were not there on the last run.

  Step 3

  Email you each one with its buyer, title, location, dates, rates and respond-by date.

• Job seeker status changes, posted to your ATS

  Build this

  Starts

  Every hour on weekdays

  Step 1

  Check the statuses of all job seekers you have submitted.

  Step 2

  Keep the job seekers whose status changed since the last run.

  Step 3

  Post each one, with its old and new status and next step, to your applicant tracking system's webhook.

• Invoice status changes, handed to your accounting system

  Build this

  Starts

  Every day at 18:00

  Step 1

  Get the invoices from the last 60 days with their statuses.

  Step 2

  Keep the invoices whose status changed since the last run, such as to Rejected, Payment Review or Paid, and stop if none did.

  Step 3

  Post invoice ID, invoice code, buyer, worker, amount and new status to your accounting system's 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 “Get job postings waiting for a response” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www.us.fieldglass.cloud.sap/get_job_postings",
    "input": {}
  }'

{
  "status": "completed",
  "data": {
    "job_postings": [
      {
        "job_posting_id": "ACMEJP00000412",
        "buyer": "Acme",
        "job_title": "Senior Java Developer",
        "location": "Chicago, IL",
        "start_date": "2026-12-01",
        "end_date": "2027-05-28",
        "rates": "Bill rate up to 95.00 USD/hr",
        "respond_by": "2026-11-14",
        "job_seekers_submitted": 0
      }
    ],
    "count": 1
  }
}

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.

Fieldglass’s own options

SAP documents supplier connectors that download job postings, time sheets and invoices, and upload job seekers, time sheets and work order acceptances. A Configuration Manager user enables them in the Connector Catalog. A REST API for talent channel systems needs a client-specific application key and your SAP Fieldglass implementation representative.

Signing in to Fieldglass

Fieldglass signs suppliers in with a username and password at the address for the buyer's data center: www.us.fieldglass.cloud.sap or the EU one. With two-factor authentication on, a one-time passcode goes to the email on your profile. With Fous you sign in once through Fieldglass's own sign-in: the login is sealed with AES-256, emailed passcodes are handled, and an expired session is signed back in.

Worth knowing

One buyer, one instance

Each buyer program is its own Fieldglass instance. Linked user accounts let you switch between them without signing out, and reporting across your supplier tenants needs SAP Fieldglass to link them.

Invoices are made one of two ways

With Auto Invoicing On, an approved time sheet becomes an invoice by itself. With it off, you create invoices in the Invoice Generator, only against the invoice billing schedule the buyer assigned you.

An invoiced time sheet cannot be changed

Once a time sheet is submitted, approved and invoiced, it cannot be rejected or adjusted. A correction goes in as a revised time sheet, and the system creates a reversal time sheet for the original.

Payment happens outside Fieldglass

Fieldglass is not an accounts payable application, so payment questions go to the buyer's company. An approved invoice shows Payment Review until it is paid, then Paid.
