How to sync users from Entra ID to your app using Node and Paycux

The best signal that a feature is right is not that people ask for it.

Paycux engineering

The best signal that a feature is right is not that people ask for it. It is that people describe their problem in the shape of it before you have built anything.

This piece walks through how we think about it at Paycux, what we have changed our minds about, and where the sharp edges are.

Prerequisites

Consider prerequisites. Defaults are the product. Most people will never open the settings screen, which means the behaviour you chose for them is the behaviour they will experience forever.

Naming is design work. If the team argues about what to call something, the disagreement is usually about what it is, and shipping before that is settled means shipping the confusion to customers.

Step 1: Install the SDK

Consider step 1: install the sdk. Ship the smallest version that is honest about its limits. A feature that does one thing completely beats one that does five things with an asterisk on each.

  • Choose defaults as carefully as features
  • Settle the name before you ship the thing
  • Ship the smallest honest version
  • Say plainly what the feature does not do

Step 2: Set secrets

That brings us to step 2: set secrets. Defaults are the product. Most people will never open the settings screen, which means the behaviour you chose for them is the behaviour they will experience forever.

Step 3: Configure the Entra ID connection

Entra ID configuration

Entra ID configuration deserves its own treatment. Naming is design work. If the team argues about what to call something, the disagreement is usually about what it is, and shipping before that is settled means shipping the confusion to customers.

Step 4: Sync users and groups to your app

That brings us to step 4: sync users and groups to your app. Ship the smallest version that is honest about its limits. A feature that does one thing completely beats one that does five things with an asterisk on each.

Where this leaves us

If there is one thing worth taking away, it is that the expensive decisions are the ones made implicitly. Making them on purpose costs an afternoon.

If you are working through the same problem and want to compare notes, the docs cover the mechanics and the console shows the behaviour on your own data.

Everything here, already built

Sign-in, enterprise SSO, directory provisioning, roles and an audit trail behind one API. Start with the quickstart and have a working sign-in this afternoon.
