 * Hi Ironikus, thank you very much for this great plugin.
    I am having problems
   connecting the plugin to an external email marketing application ([https://encharge.io/](https://encharge.io/)).
   When I try to map the data and save it, I get the message “error while saving.
   Unsupported Unicode escape sequence”. I contacted the application’s customer 
   service and they tell me that the problem is caused by a specific field. They
   ask me if the WP Webhooks plugin allows me to change the name of the field. Is
   that possible? Do you know how I could solve this problem? Thanks!

 * Hey [@aguadap](https://wordpress.org/support/users/aguadap/) – Thank you very
   much for your message.
    It’s surely solvable, the only question is how. 🙂
 * To help you further, it’ll be great if you can let me know if the field is a 
   subfield, on the first layer, or somewhere else.
    Depending on where it is located
   and how it looks like, I’ll be able to share more details. Thank you already 
   very much.

 * Hi [@ironikus](https://wordpress.org/support/users/ironikus/) ,
    sorry for not
   responding sooner, I didn’t get the reply notification. I really don’t know how
   to answer your question, sorry :/ What I can do is show you what WP webhooks 
   generates and the line that Encharge say is causing problems. This is what WP
   Webhooks shows me:

           ]
         }
       }
       ```
   
 * And the Encharge people told me:
    “It seems the issue is coming from this field:“\
   u0000WP_User\u0000site_id” Would you check if the WP Webhooks plugin allows you
   to change the name of this field?”
 * I don’t know if this information is enough for you to help me. If you need more
   information, please, let me know.
    Thanks!

 * Hey [@aguadap](https://wordpress.org/support/users/aguadap/) – Thanks for the
   update. Can you please let me know if you use the latest version of our plugin?
 * If you want to alter that specific value, you can write some lines of code for
   re-formatting the data using the following filter: [https://wp-webhooks.com/docs/knowledge-base/filter-webhook-trigger-data/](https://wp-webhooks.com/docs/knowledge-base/filter-webhook-trigger-data/)
 * Within the pro version of our plugin, we also offer a data mapping template that
   you can use to alter and/or remove specific fields from the response. This could
   also solve the problem.
 * Do let me know in case you have any further questions.
