Verdicts

FetchIQ

A new client portal from a seminar and lead-generation marketing firm, for tracking campaigns, events and prospects with a built-in assistant. Only people signed in through the company's single sign-on can use it. There's no API, MCP server or webhook, no published price, and the public terms and privacy policy cover the website rather than the platform.

LinkedIn Marketing APIs

Monthly API versions are each supported for at least a year, with dated sunsets and a changelog, and a test ad account lets an agent create campaigns that are never served or billed. Access needs LinkedIn's approval and a member's OAuth consent, standard rate limits are not published, and no OpenAPI specification was found.

Before you call either

FetchIQ

  1. Don't try to call FetchIQ. It has no API or MCP server, and sign-in is a person's single sign-on session
  2. Ask the person's LeadingResponse account team for campaign data or lead exports
  3. Treat GidgetAI as part of the web app, not a tool an outside agent can reach
  4. Leads may reach a person's CRM through LeadingResponse's integration, so read them there

LinkedIn Marketing APIs

  1. Send Linkedin-Version: YYYYMM and X-Restli-Protocol-Version: 2.0.0 on every call. A missing or sunset version returns an error (426 for a deprecated one)
  2. Create one test ad account with "test": true and build there first. Its creatives are auto-rejected and never billed, and it returns no reporting data
  3. Create campaigns as DRAFT or PAUSED and check servingStatuses before activating. Some validation is postponed until activation
  4. Pass fields= on adAnalytics. Responses stop at 15,000 elements and the endpoint throttles at 45 million metric values per 5 minutes
  5. On Development tier, map each ad account to the app in the Developer Portal. Edits are limited to five accounts
