Questions about create_reddit_ads_lead_form
REDDIT HAS RETIRED THIS, SO IT NOW REFUSES, AND IT CANNOT BE REPLACED LIKE FOR LIKE. Reddit removed onsite lead forms entirely: the API sunset on 2026-09-21 by Reddit’s changelog (their migration guide said 2026-09-30 for the same change; Hermoso stopped creating on the earlier date), Reddit’s API reference now marks the create call deprecated and it answers 410 Gone from 2026-09-30, and Reddit paused every ad still using an onsite form on 2026-09-30. So this tool refuses for free, before calling Reddit, and says what to do instead. DO NOT BUILD A NEW FUNNEL ON IT: Reddit’s replacement is an OFFLINE form on the advertiser’s own landing page, measured with the Reddit Pixel or the Conversions API — list_reddit_ads_pixels and send_reddit_ads_conversions, both of which work here today — inside an offsite lead generation campaign (create_reddit_ads_campaign with objective LEAD_GENERATION). Existing forms stay readable with list_reddit_ads_lead_forms. What it used to do: create a lead generation form — the in-feed form redditors fill in without leaving Reddit, used by LEAD_GENERATION campaigns. Reddit requires a link to a real privacy policy on every form. Ask for the FEWEST fields that make a lead useful: every extra question costs completions. KNOW THE LIMIT BEFORE YOU PROMISE ANYTHING: Reddit exposes no way to attach a form to an ad through the API — there is no lead-form field on an ad, an ad group or a post — so the user picks this form in Reddit’s Ads Manager when building the creative, and downloads its leads from there. There is also no update and no delete, so get the questions right the first time. Free. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
