🟢feedletter_list_surveys(q, page)
List or search your FeedLetter surveys (newsletter surveys, one-time polls and web rating widgets), newest first, 50 per page. q matches the name, id or external_id. Each item has id, type, name, external_id, public_title and created_at. While has_more is true, call again with page + 1. Read-only. FeedLetter API: GET /v2/surveys.

}🟢feedletter_get_survey(survey_id, results_only)
Get one survey by its FeedLetter survey id: settings, placement code (links or embed_html), analytics (votes, daily votes, sentiment) and all feedback. Set results_only to true for just the identity, analytics and feedback. Use the survey id, not the external_id. Read-only. FeedLetter API: GET /v2/surveys/{id}.

"$schema": "https://json-schema.org/draft/2020-12/schema"
}🟢feedletter_get_wall_of_love(wall_id)
Get the feedback that one Wall of Love shows, to build your own wall. Each item has id, comment, name (when shown), answer_label, created_at and survey_title. Comment and name are HTML-escaped. Business plan only: other plans get 403 plan_required. Read-only. FeedLetter API: GET /v2/walls-of-love/{id}.

}🔴feedletter_create_survey(type, name, public_title, external_id, text_template, ...)
Create a newsletter survey, a one-time poll or a web rating widget. Needs a Read & write key. Only type and name are required. Newsletter and poll responses return links (one voting link per answer) and email_html; web ratings return embed_html. Set external_id to your own stable id: a second call with the same external_id returns the existing survey (HTTP 200, already_exists) and changes nothing. Without external_id, each call creates a new survey. Do not combine copy_from with text_template. FeedLetter API: POST /v2/surveys.
