What HubSpot Marketing Campaigns (BYOK) is for

HubSpot Marketing Campaigns (BYOK) lets an AI assistant read your own HubSpot Marketing Campaigns data through the HubSpot Marketing Campaigns API with a key you supply (HubSpot private app access token (scope: marketing.campaigns.read; revenue report also marketing.campaigns.revenue.read)). Read-only: 6 tools (list_campaigns, get_campaign, get_campaign_metrics, get_campaign_revenue, get_campaign_budget, list_campaign_asset_types). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.hubapi.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by HubSpot Marketing Campaigns. HubSpot Marketing Campaigns and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which marketing campaigns are active in HubSpot?"
• "Show HubSpot campaign edb9b6c3 with its assets"
• "How many sessions did HubSpot campaign edb9b6c3 drive?"
• "How much revenue is attributed to HubSpot campaign edb9b6c3?"
• "What is the budget and spend of HubSpot campaign edb9b6c3?"
• "What kinds of assets can a HubSpot campaign hold?"

What it does

• list_campaigns: List marketing campaigns with name, status, dates, audience, budget and spend totals. Marketing Hub Professional or Enterprise.
• get_campaign: Get one campaign's properties and the ids of its assets. Give a date range to include asset metrics for that period.
• get_campaign_metrics: Get a campaign's aggregate traffic numbers: sessions, influenced contacts and new contacts by first and last touch. Counts only.
• get_campaign_revenue: Get revenue attributed to a campaign: revenue, deal amount, number of deals and contacts, with a chosen attribution model.
• get_campaign_budget: Get a campaign's budget and spend: totals, remaining budget, and each budget and spend line with name and amount.
• list_campaign_asset_types: List the asset types that can be attached to a campaign (for example marketing emails, landing pages, forms).

BYOK key

You bring your own HubSpot Marketing Campaigns HubSpot private app access token (scope: marketing.campaigns.read; revenue report also marketing.campaigns.revenue.read) (https://developers.hubspot.com/docs/apps/legacy-apps/private-apps/overview). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.hubapi.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

HubSpot Marketing Campaigns (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What HubSpot Marketing Campaigns (BYOK) is. HubSpot Marketing Campaigns (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own HubSpot Marketing Campaigns data: Read your HubSpot marketing campaigns with dates, status, budget and spend, plus aggregate traffic and revenue reports, with your own private app token. You bring your own HubSpot Marketing Campaigns HubSpot private app access token (scope: marketing.campaigns.read; revenue report also marketing.campaigns.revenue.read); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one HubSpot Marketing Campaigns call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.hubapi.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If HubSpot Marketing Campaigns rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What HubSpot Marketing Campaigns receives. The request we make on your behalf, including the key and the arguments, under HubSpot Marketing Campaigns's own terms and privacy policy. HubSpot Marketing Campaigns acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer HubSpot Marketing Campaigns gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your HubSpot Marketing Campaigns data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. HubSpot Marketing Campaigns (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at HubSpot Marketing Campaigns at any time to end all access.

Children. HubSpot Marketing Campaigns (BYOK) is a general-audience service operated by the adult using the assistant, under HubSpot Marketing Campaigns's own age rules.

Changes. We will post changes here with a new effective date.
