web3forms

web3forms_create_submission

WRITE: create a submission on a form you own, as if a visitor sent it. It is stored, counts toward the monthly quota, and sends the notification email, autoresponder and integrations. Needs a key with the 'Create submissions' permission. There is NO idempotency key: if a call times out, check web3forms_list_submissions before you retry, or you may create a duplicate. API: POST /submissions.

web3forms_get_submission

Get one submission by id (for example sub_a1b2c3d4e5f6), with its fields, IP address, user agent, site_url and attachments. API: GET /submissions/{id}.

web3forms_list_forms

List all Web3Forms forms in the account: form_id, form_name, created_at and total_count of submissions. Good first call to find a form_id. API: GET /forms.

web3forms_list_submissions

List submissions of one form, newest first, with fields, submitter IP address, user agent, site_url and attachments. Returns has_more and next_cursor: pass next_cursor as cursor to get the next page. API: GET /submissions.
