topic Hubspot Addon - to many request based on form submission in APIs & Integrations https://community.hubspot.com/t5/APIs-Integrations/Hubspot-Addon-to-many-request-based-on-form-submission/m-p/359234#M35325 Hi, Recently I have developed a Addon, using my Hubspot Dev Account. This app sends a webhook to the endpoint of my application. The main goal here is to create or update a deal to a contact, based on a Hubspot form. For that, my app needs to check if there is a deal for this contatc request, before create or update a deal.  The webhook scopes are:- contact.creation- propertyOne -> contact.propertyChange - propertyTwo -> contact.propertyChange So far, so good... the app is working fine. But recently I detected a problem:If the user clicks several times at the submit button on the form, Hubspot sends to my app the same number of requests, before the user been redirected to the "thank you" page. The result is a duplicated or triplicated "deal" in Hubspot. Can anyone help me with that? Thanks, PS: the form and the page, both was created using Hubspot native tools (Form and Design tools ). It's not a embedded form in a external site.  Mon, 03 Aug 2020 21:41:22 GMT hilton22 2020-08-03T21:41:22Z
