Webhook Error “400 Bad Request”

  • Hi,

    I saw that other users also had problems with the latest version of the plugin.

    Since January 2nd we have been receiving the automatic plugin warning about a malfunction in one of the site’s forms:

    

    - Form: #7361 - Lead tank 5-2 
    - Webhook: Don't post webhook URL
    - Error: "Webhook returned an error code."
    




    Request Method: POST
    




    Request Headers:
    {"Content-Type":"application\/json; charset=UTF-8","To get utm_source":"https:\/\/example.com\/?utm_source=example","Use this shortcode":"[hidden utm_source default:get]"}
    




    Request Body:
    "Maybe don't post that either"
    




    Response Code:
    400
    




    Response Message:
    "Bad Request"
    




    Response Headers:
    {}
    




    Response Body: "<html>\r\n<head><title>400 Bad Request<\/title><\/head>\r\n<body>\r\n<center><h1>400 Bad Request<\/h1><\/center>\r\n<hr><center>nginx<\/center>\r\n<\/body>\r\n<\/html>\r\n"
    




    If you plugin is active the contact form submission shows a generic submission error; by disabling the plugin the form starts without problems.

    Obviously we haven’t changed anything in the original form since a few months..

    Thank you

    Hi.

    As you can see in your notification, your webhook is returning a error: 400 Bad Request

    Please, check your Zapier integration.

    I am also getting some weird errors since the recent update “An error of type E_PARSE was caused in line 439”.

    Asking ChatGPT to review this code snippet:

    wp_mail(
    $error_mails,
    sprintf( __( ‘[%s] Webhook Error on Form %s’, ‘cf7-to-zapier’ ), wp_specialchars_decode( get_option( ‘blogname’ ), ENT_QUOTES ), $form ),
    $notification,
    );

    ChatGPT said:

    Possible Issue:

    • In this wp_mail function call, the trailing comma , after the third parameter ($notification) is incorrect syntax. In PHP, there should not be a comma after the last parameter in a function call.
    • Correct this by removing the comma at the end of the parameters.

    Here’s how the fixed function should look:

    wp_mail(
    $error_mails,
    sprintf( __( ‘[%s] Webhook Error on Form %s’, ‘cf7-to-zapier’ ), wp_specialchars_decode( get_option( ‘blogname’ ), ENT_QUOTES ), $form ),
    $notification
    );

    Not sure if this issue is related… our webhooks are working, but just getting this error which was not happening before the recent update.

    Thanks for pointing this! I’ll check it out.

    But no: It’s not related. The notification means everything is OK, but your server is returning a 400 Bad Request.

    Said that, I figured maybe your header is broken: 

    {"Content-Type":"application\/json; charset=UTF-8","To get utm_source":"https:\/\/example.com\/?utm_source=example","Use this shortcode":"[hidden utm_source default:get]"}

    “To get utm_source” and “Use this shortcode” are pretty sure a invalid header. Remove everything from headers option and try again, please.
