    I currently have PayPal Pro payment Integration on several forms. However i recently discovered that only one form works and the others show an error message that states "Security Header missing". I attempted to re-enter the API information, however after showing successful Testing for the integration it continues to show the error message upon submission.

    I have inspected form you provided and you did not integrated your form with PayPal Pro.

    Error message "Security header is not valid" means that there is an issue with your API Credentials in the Paypal Pro payment field.  Please make sure that you are entering the correct API username, password, and signature. For example, you might have an extra character, a wrong character or less characters added for API credentials, which causes this.

    Here's how you can get your Paypal Pro API Credentials: 

    Hope this will help. Let us know if you need further assistance.
