This communication was sent 1st September 2026. Sage 200 We recently contacted your organisation about important changes to how we register and manage Sage 200 API access. Our records show that the email address we used for our previous communication is no longer valid and that you don't have a valid Sage account linked to your Sage 200 API access. As a result, we're contacting you using alternative details to ensure you're aware of these changes and the actions required to maintain your Sage 200 API access. Updated requirements for Sage 200 API access - You must have a valid Sage account to request and maintain API access.
- We must register all API requests under a master registration.
- You need to register each developer app separately and use unique credentials.
- Each app can receive:
- Development (Test) credentials supporting up to 20 authentication requests per minute.
- Production credentials supporting up to 600 authentication requests per minute.
- If you're the developer of an app, whether it's used by a single customer or multiple customers, you must request the API credentials directly.
- Customers shouldn't request API credentials on your behalf.
