This guide shows you how to register your own app with simPRO to obtain your OAuth credentials (client id & secret). These are required to let your users grant your app access to their simPRO account. simPRO offers two paths depending on whether you’re integrating against a single build (typical for in-house tooling) or building a public integration distributed to many simPRO customers.Documentation Index

Path 1 — single-build OAuth app (in-house use)
Use this path if you only need to connect to your own simPRO build.Log in to your simPRO build
Go to
https://<your-build-name>.simprosuite.com/ and log in with an admin account.Create a new application
- Click Create Application
- Fill in: Company, Name, Email Address
- Redirect URI: enter
https://api.nango.dev/oauth/callback - Authentication Method: select
OAuth 2.0 - Grant Type: select
Authorisation Code - Click Create
Get your credentials
Copy your Client ID and Client Secret from the application detail page (or download the key file simPRO offers on creation). You’ll need these when configuring the integration in Nango.
Next
Follow the Quickstart to connect your first account. Note that this app’s credentials only work against the build it was created in — if you need to connect multiple customer builds, see Path 2.
Path 2 — central partner OAuth app (multi-tenant integrations)
Use this path if you’re building a public integration that connects to many simPRO customers’ builds.Sign the Simpro Group Partner Program Agreement
Apply at simprogroup.com/partners and complete the partner programme agreement. You’ll get access to the Simpro Group Partner Network portal at simpro.allbound.com.
Submit the integration approval form
From the partner portal, find Integration Approval Process and Technical Guidelines. The PDF describes a 2-phase approval (submit integration name, description, redirect URIs → Simpro reviews → central credentials issued).
Specify your Nango callback URL
In the integration approval form, set the redirect URI to
https://api.nango.dev/oauth/callback.Receive central OAuth credentials
After approval, the Simpro Group partner team will issue you a central client ID and secret that work across every customer’s simPRO build. Use these in your Nango integration settings.
Next
Follow the Quickstart to connect your first customer’s account. Each customer enters their own simPRO build name when authorising.
