whatconverts_list_leadsList tracked leads (phone calls, web forms, chats, texts, emails, events, transactions) with source/medium/campaign/keyword attribution, contact details, quote and sales values, call duration and transcripts. start_date is REQUIRED because WhatConverts otherwise returns only toda
whatconverts_get_leadOne lead by id with every field: type, status, attribution (source, medium, campaign, keyword, landing page), contact details, location, device, quote/sales value, call details, transcripts, form/message content, and custom fields. GET /leads/{lead_id}.
whatconverts_get_call_recording_infoRecording and voicemail facts for a phone-call lead: the recording and voicemail links, call duration, answer status, tracking/caller numbers and the call/voicemail transcripts. Returns links and text only, never audio. Taken from GET /leads/{lead_id} (the audio endpoint GET /rec
whatconverts_update_leadWRITE: update a lead's sales data in WhatConverts: quotable state, quote value, sales value, the URL where the lead occurred, and/or custom/additional field values. Only the fields you pass change; it overwrites the previous values of those fields. Sends no notifications. At leas
whatconverts_create_leadWRITE: add a lead to WhatConverts, for example an offline phone call, a form submission from another system or a sale you want attributed. It appears in reports and counts toward lead totals; send_notification is always off, so no emails go out. Not idempotent: calling twice crea
whatconverts_list_accountsAgency key only: list the accounts (clients) of the agency with their profiles (id, name, date created). Use the ids to filter leads. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). GET /accounts.
whatconverts_get_accountAgency key only: one account by id with its profiles. GET /accounts/{account_id}.
whatconverts_list_profilesAgency key only: list the profiles (websites/campaign sets) of one account. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). GET /accounts/{account_id}/profiles.
whatconverts_get_profileAgency key only: one profile by id (name, date created). GET /accounts/{account_id}/profiles/{profile_id}.
whatconverts_list_usersAgency key only: list WhatConverts users (email, role, whether activation is pending) of the master account or of client accounts. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). GET /users.
whatconverts_get_userAgency key only: one user by id with role, notification settings and (for account users) the accounts they can access. GET /users/{user_id}.
whatconverts_list_rolesAgency key only: list user roles (id, name, master-account or account type). GET /roles.
whatconverts_get_roleAgency key only: one role with its permission levels (none/view/edit) per area. GET /roles/{role_id}.
whatconverts_list_phone_numbersList the call-tracking numbers: tracking and destination number, call flow, trigger (source/medium), call recording and messaging flags, last used. A Profile key lists its own profile; an Agency key may filter by account_id/profile_id. GET /tracking/numbers.
whatconverts_list_web_formsList the web forms WhatConverts tracks (id, name, how the form and its submit are matched on the page). A Profile key lists its own profile; an Agency key may filter by account_id/profile_id. GET /tracking/forms.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.22.3) reached the registry yesterday.
