Unable to save document (form submissions) with REST API

[thefrana]

Hi,
I tried payloadcms/plugin-form-builder and I have some questions. How to create form submissions? Should I point my HTML directly to Payload? Richt now, I have proxy function that process data and after that I tried to create new form submission using REST API.

const formSubmission = {
  form: '<some-mongo-id>',
  submissionData: [
    { field: ...', value: '...' },
    ...
}

const res = await apiFetch('<api-url>/form-submissions', {
  body: JSON.stringify(formSubmission),
  method: 'POST',
})

const formData = new FormData()
formData.append('_payload', JSON.stringify(formSubmission))

const res = await apiFetch('<api-url>/form-submissions', {
  body: formData,
  headers: {
    'Content-Type': 'multipart/form-data',
  },
  method: 'POST',
})

Neither of these approaches work. They return validation error that prop form is missing, Do you have any ideas what I am doing wrong? I think the documentation lacks details on how to work with REST mutations.

Thanks!

That should work...

Here is a snippet pulled from a site my team built.

const dataToSend = Object.entries(data).map(([name, value]) => ({
  field: name,
  value
}));

const req = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/api/form-submissions`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    form: formID,
    submissionData: dataToSend
  })
})

Thank you, I think the problem was that I did not specified Content-Type. Dummy mistake!
