Why build on Add to CRM
One integration covers the whole capture-to-CRM job — with predictable pricing and errors you can actually debug.
- One API, not three. Enrichment, email verification, people search, and CRM sync behind a single integration — instead of stitching together separate vendors.
- Credits, not overages. Calls draw from your plan's monthly credits — shared with the dashboard and extension. Buy once, use everywhere, with no per-request fees.
- No-code friendly. Any tool with an HTTP request step, such as Zapier, Make or n8n, can call the API with your key. There is no separate app to install.
- Debuggable by design. Every response carries a request_id, and failures use one consistent error envelope with a machine-readable type — so issues are quick to trace.
Frequently asked questions
Anything that needs B2B contact data or CRM writes — enrich leads from a signup form, verify emails before importing, build targeted prospect lists, or sync enriched contacts into a CRM. Call it from your own code, or from no-code tools such as Zapier, Make and n8n through their HTTP request steps.
