Hello I am trying to use the HubSpot form API to send information to a form using fields I made with HTML. This is the code: var formDataA = new FormData(document.getElementById(‘form1’)); var formDataB = new FormData(document.getElementById(‘cotizador\_paso2’)); var combinedFormData = new FormData(); combinedFormData.append(‘firstname’, formDataA.get(‘firstname’)); combinedFormData.append(‘lastname’, formDataA.get(‘lastname’)); combinedFormData.append(‘email’, formDataA.get(‘email’)); combinedFormData.append(‘phone’, formDataA.get(‘phone’)); combinedFormData.append(‘escuela\_de\_procedencia’, formDataB.get(‘cotizador\_datospreuniversitario\_escuela’)); combinedFormData.append(‘estado\_de\_procedencia’, formDataB.get(‘cotizador\_datospreuniversitario\_estado’)); combinedFormData.append(‘periodo\_de\_ingreso’, formDataB.get(‘cotizador\_datosgenerales\_periodoingreso’)); combinedFormData.append(‘licenciatura\_de\_interes’, formDataB.get(‘cotizador\_datosgenerales\_licenciatura’)); combinedFormData.append(‘eres\_preuniversitario\_o\_padre\_de\_familia\_’, ‘Padre de familia’); fetch(`[https://api.hsforms.com/submissions/v3/integration/submit/myFormID/myPortalID\`](https://api.hsforms.com/submissions/v3/integration/submit/myFormID/myPortalID%5C%60), { method: ‘POST’, headers: { ‘Content-Type’: ‘application/json’ }, body: JSON.stringify(Object.fromEntries(combinedFormData)) }) .then(response =\> response.json()) .then(data =\> { console.log(‘Success:’, data); alert(“Thanks!”); }) .catch((error) =\> { console.error(‘Error:’, error); }); The request gets sent successfully, but this is what I receive on the other side: ![Gerardo_S_0-1732130407371.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/9/a/9a0b15af0df5bfa8678ccc6383c413a458d323c2.png) And all the fields are empty. If you guys could help me with this I would really appreciate it. ---

Hi [@Gerardo\_S](https://community.hubspot.com/t5/user/viewprofilepage/user-id/860212) and welcome, we are delighted to have you here! Thanks for asking the Community! You are trying to update contact properties once a form has been submitted. Please let me know if that’s not the case. I’d like to share these documentation that might help you: - [Imports API](https://developers.hubspot.com/beta-docs/guides/api/crm/imports) - [Update contacts API](https://developers.hubspot.com/beta-docs/guides/api/crm/objects/contacts#update-contacts) - [Properties API](https://developers.hubspot.com/beta-docs/guides/api/crm/properties) I also wanted to invite a couple of subject matter experts to this conversation: Hi @Teun, @SRalston05, @GRajput and [@zach\_threadint](https://community.hubspot.com/t5/user/viewprofilepage/user-id/324811) do you have tips to share with [@Gerardo\_S](https://community.hubspot.com/t5/user/viewprofilepage/user-id/860212), please?

Hello, thank you for your prompt response. Actually, what I’m trying to do is use the “Submit Data for a Form API”. I’ve been using this documentation as a reference: [Forms API V3 documentation](https://developers.hubspot.com/beta-docs/reference/api/marketing/forms/v3-legacy#submit-data-to-a-form-supporting-authentication) When I fill out the form the normal way, the data appears on the submissions tab as normal. However, when I try to send data the way I’m doing in the code, all the columns are empty and it displays some error messages. Here’s what it looks like: ![Gerardo_S_0-1732223578045.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/6/9/69cfd2f2d0719c24fae3ad671d9a71554e2e6837.png) -- ![Gerardo_S_1-1732223618044.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/b/e/be19d021ce384d3e80fd1fcfffb25b499253ecd2.png) -- ![Gerardo_S_2-1732223651331.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/2/a/2a0052216f23d83af4a62141473ee1d70a697472.png) -- If you need any more details please by all means ask. ---

Hi [@Gerardo\_S](https://community.hubspot.com/t5/user/viewprofilepage/user-id/860212) 👋 A couple of thoughts: 1. You’ve specified your API endpoint as _[https://api.hsforms.com/submissions/v3/integration/submit/\*\*myFormID\*\*/\*\*myPortalID](https://api.hsforms.com/submissions/v3/integration/submit/ **myFormID** /**myPortalID)\*\*_ 1. HubSpot’s documentation has the portal ID path parameter first, then the Form GUID, e.g. _[https://api.hsforms.com/submissions/v3/integration/secure/submit/\*\*:PORTAL\_ID\*\*/\*\*:FORM\_GUID](https://api.hsforms.com/submissions/v3/integration/secure/submit/ **:PORTAL%5C_ID** /**:FORM%5C_GUID)\*\*_ 2. I think it could be helpful for you to share an example request body -- i.e. the contents of _Object.fromEntries(combinedFormData)_ I hope that proves helpful. Please let me know if you have any follow-up questions. ---

Hi, Perhaps your json data are not well shaped. You send this: ```lia-code-sample { "firstname": "John", "lastname": "Doe", "email": "john@example.com", ... } ``` But I think you should send this: ```lia-code-sample { "fields": [ { "name": "firstname", "value": "John" }, { "name": "lastname", "value": "Doe" }, { "name": "email", "value": "john@example.com" }, // etc. ], "context": { "pageUri": "https://www.example.com/your-page", "pageName": "Your Page Name" } } ``` Tell us if it works like that. Best
