Getting started with Power Automate

How to setup your Power Automate flow to start using PDF Blocks.

PDF Blocks is a connector for Power Automate, Power Apps, and Azure Logic Apps. This guide is focused in Power Automate, but you can apply most of it for Azure Logic Apps as well.


To start using PDF Blocks, you need:

  • A paid Power Automate plan with either a per-user plan or a per-flow plan.
  • A PDF Blocks account. If you don’t have one, you can start a 14-day trial.

Your API key

You can get your API key in your dashboard.

This API key only gives the holder (for example your Power Automate account) access to the PDF Blocks service. Someone with the API key can’t access your documents or private input data because we don’t store your documents or data. Anyway, keep it safe and don’t post it in public.

If you want to reset your API key, contact support.

Step 1: Choose PDF Blocks

In a Power Automate flow, add a new action. In the Choose an action panel search for PDF Blocks, and click the PDF Blocks icon.

Create a connection in Power Automate

Check you have selected PDF Blocks and not Integrable. Both icons look similar.

Step 2: Create a connection

The first time you add a PDF Blocks action to a flow, Power Automate will ask you for some parameters to create a connection:

Create a connection in Power Automate

Connection parameters:

  • In Connection Name, write any string you want to use as the name of the connection. In the example above we used “My PDF Blocks connection”.
  • In API Key, write your PDF Block API Key. As you write it, it will be masked by dots like any other password.
  • In Server Hostname, Leave it blank to use any available server. EU Users: If you want your documents processed exclusively in European servers, write in the box.

Press Create to create your connection. After the connection is created you are ready to start using PDF Blocks in any of your flows.
