This communication was sent 17th August 2026. Sage 200 We're contacting you because you have a valid Sage account and use, or have requested access to, the Sage 200 Application Programming Interface (API). We want to let you know about some important changes to the way we register and manage Sage 200 API access. What’s changing To support these changes, we'll publish new documentation and introduce updated processes and guidance for Sage 200 API access. The new API access model will require the following changes: - You’ll need a valid Sage account to request and maintain API access
- We’ll register all API requests under a master registration
- You must register each developer app separately with unique credentials. Two credentials per app are available:
- Development (Test) credentials will support up to 20 authentication requests per minute
- Production credentials will support up to 600 authentication requests per minute
- If you develop an app, whether it’s used by a single customer or multiple customers, you’ll need to request the API credentials directly
- Customers shouldn’t request API credentials on your behalf
What this means for you We’ll send a separate email with your API master registration (known as a serial number) details soon. The account and registration information are mandatory requirements for continued Sage 200 API access. You'll also need these details if you contact Sage for support or assistance relating to the Sage 200 API. Reminder When using the Sage 200 API, you must comply with the: These requirements apply to all API access requests and support the controls we're introducing to manage API registrations. If any of your credential requests don't align with these requirements, the Developer Services Licence Agreement, or the Acceptable Use Policy, contact the Developer Services Support Team by 31 August 2026 so we can review them with you. Coming later in 2026 You’ll need to submit credential requests through an App Registry on developer.sage.com Help and support Visit the Community Hub, access the Developer Portal, or search the Sage Knowledgebase.
