# 92007: The Content Variables Parameter is invalid

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when `ContentVariables` is not sent in a valid format. Send `ContentVariables` as a JSON string of key-value pairs for the variables in your content template. When you include `ContentVariables`, also include `ContentSid`.

### Possible causes

* You sent `ContentVariables` as an object, array, or another value instead of a JSON string.
* The JSON string is malformed because it contains invalid quotes, commas, braces, or escaping.
* One or more `ContentVariables` values are null or empty strings.
* For approved WhatsApp templates, a variable value contains a newline.

### Possible solutions

* Serialize the variable payload to a JSON string before sending the request. If you use a helper library, pass `contentVariables: JSON.stringify({...})`.
* Validate the JSON before sending the request and confirm it contains valid key-value pairs for your template variables.
* Include `ContentSid` with `ContentVariables`.
* Replace null or empty values with valid substitutions, or omit a value so the template can use its default placeholder value.
* If you are sending an approved WhatsApp template, remove newline characters from variable values and verify the template follows WhatsApp variable rules.
