Allowances API for Make

Official GSA, DSSR and DTMO per diem and allowance rates in your Make scenarios. A ready-made module for every endpoint: no HTTP module, no JSON parsing.

Look up a rate, run a calculator, send the result to any of the 2,000+ apps in Make.

Install the Make app Get an API key

The app is invite-only while Make reviews it; the link above installs it in your Make account. Requires a paid plan (Pro or Business).

What you can build

Expense automation

Fill the per diem column of every expense report in Google Sheets or Airtable from the trip's ZIP code and dates.

Proposal pricing

Pull DSSR COLA, hardship and danger pay for every post in a bid and write the totals back to your pricing model.

Rate change alerts

Watch the latest publication dates and post to Slack or email when GSA, DTMO or DSSR publish new rates.

How it works

  • ✓ Connect once with your Allowances API key. Every module uses that connection.
  • ✓ Rates by country, post, post code, US state, ZIP code or GSA destination, as of any effective date. Leave the date empty for current rates.
  • ✓ Search modules emit one bundle per location, country or destination, ready to iterate; API errors appear as readable messages in the scenario.
  • ✓ Each module run is one API request against your plan's quota. Historical dates follow your plan's rules, exactly like the REST API.

Set up in three steps

  1. 1

    Install the app

    Open the invite link while signed in to Make and accept it. The Allowances API app appears among your apps.

  2. 2

    Create the connection

    Add any Allowances API module to a scenario and paste the API key from your dashboard when Make asks for a connection.

  3. 3

    Map the result

    Lodging, M&IE, allowances and dates come out as typed fields you can map to the next module.
