Zoho Creator API no longer accepting POST requests to update data

Hello,

I'm attempting to make an HTTP POST to a form which was working previously however over the last few weeks it would appear that things have stopped working. We don't entirely know why, so I'm curious to know if something has changed on the server side that is causing the update requests to get rejected.

Here is my request
  1. POST https://creator.zoho.com/api/escarpmentlabs/xml/db/form/Orders/record/update

  3. BODY (Copied from Bulk Editor from Postman)
  4. criteria:Order_Number=203328
  5. Notes:What is going on?
  6. authtoken:abracadabra <obviously not the actual auth token>
  7. scope:creatorapi
  8. zc_ownername:escarpmentlabs
I'm getting the following in my response
  1. <response>
  2.     <result>
  3.         <form name="Orders">
  4.             <update>
  5.                 <criteria>Order_Number=203328</criteria>
  6.                 <newvalues>
  7.                     <field name="Notes">
  8.                         <value>What is going on?</value>
  9.                     </field>
  10.                 </newvalues>
  11.                 <status>Failure, Failed to update data.</status>
  12.             </update>
  13.         </form>
  14.     </result>
  15. </response>
What could be going on that is preventing the records from updating and is there anything on the client side I need to correct in order for this to start working again?
