REST API criteria in update request

REST API criteria in update request

Hello,

I've tried to update my Zoho Creator View by using Email as criteria.
  1. $criteria = "Email=$user_info->user_email";
The response is a failure, with the following response :

update: {"formname":["User",{"operation":["update",{"newvalues":[{"WP_ID":"135","WP_login":"f","Origine":"wordpress"}],"criteria":"Email = f@mail.com","status":"Failure, No Records Found With Specified Criteria."}]}]}


f@mail.com obviously exists in my zoho creator view, and a test based on another criteria ( WP_login ) works.

Is that because of the symbol "@", if so how can I update my table using this email criteria?

Thanks in advance,
