Below, we wanted to share some of the most common error codes developers might run into so that you and the developer have an idea of how to troubleshoot them. Keep in mind that the codes below are the most likely errors, but these might change depending on the exact error. A full list of error codes and explanations can be found here. 

• 500 - Your API key has not been properly set up. Please contact API support.  Your key has not been properly set up for the MLS user.    
• 403 - This key is restricted to specific IP addresses and/or User-Agent values.
• 403 - This key is restricted from accessing this endpoint. Please use replication.sparkapi.com
• 429 - Over rate limit
• 403 - The Flexmls account associated with this API key is inactive or has their system access turned off. Please contact MLS staff to resolve if you feel this is in error.
• 401- The request was made by a disabled OAuth client.

• The MLS admin home screen now features an expanded to-do section, serving as a centralized list of outstanding items in need of MLS action. The section displays up to three key categories:
  • Data Plan Subscriptions Awaiting MLS Approval
  • Licensees Awaiting MLS Approval
  • Past Due Licensee Updates

• The Subscription page now includes a filter to only show data plan subscriptions with pending licensees that haven’t been fully approved, allowing MLS admins to easily see where follow-ups or MLS approvals are needed.

• Finally, the Manage Licensees page is now ordered to show all pending licensees at the top of the page, rather than presenting them in the order in which they were reported.
