Hello,
To find Auth0 users based on a metadata field value contained in a list of several hundred options, you can use the Auth0 Management API’s “Get Users” endpoint with a query parameter (q) for filtering. Auth0 supports a simplified query syntax where you can specify conditions like metadata.fieldName:(value1 OR value2 OR … OR valueN) to find users. For instance, if your metadata field is named myField and you want to find users with values 1, 2, or 3 in myField, your query would be q=metadata.myField:(1 OR 2 OR 3). This approach avoids the need to concatenate numerous OR clauses manually, making it efficient and straightforward to filter users based on your criteria. Ensure you handle pagination if the result set is large, as the API response will be paginated by default.
Best Regard,
James Huber
