Status Code 400 Bad Request

Last updated: апрель 20, 2020


Your Zap is likely to be missing a required field, or a field value wasn't in a recognized format. For example, if a field in your action step is expecting an email address, but the value given is a name, the app may return a 400 error.


Check that your fields are correctly set up and mapped to each other.


I tried to change facebook leadform, to created a new form, but nothing has changed. What exactly needs to be done to fix the error?
