No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key. - `api_key` lemlist API key: in lemlist open Settings > Integrations and generate an API key. lemlist uses HTTP Basic auth with… ``` account { op: "connections.requirements", service: "lemlist" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### Make the first call. Check before a write. Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free. ``` do { action: "lemlist.team.get" } # get team · read · 1 upstream call check { action: "lemlist.contacts.delete", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` lemlist at a glance **Sign-in** Username and secret.

The free call account { op: "connections.requirements", service: "lemlist" } lists exactly what to paste. **Can an AI agent delete or change things in lemlist?** Only if its key allows it, and only with an explicit confirmation. 29 lemlist actions are destructive, including delete Contact, delete Company and merge Contacts. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it. **Will an AI agent use up my lemlist API limit?** actionlake paces every call to the limits in the lemlist service file: 20 calls per 2 seconds per connection. Repeated reads are answered from cache (79 lemlist actions can be), which never reaches lemlist. **What does a lemlist action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (206 lemlist actions page). Cache hits, searches, dry runs and calls lemlist refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card.

It is built from lemlist's documentation as read on 23 October 2026. 206 actions in 75 areas, each one in the signed service file (version 1.0.0). **Can I combine lemlist with my other systems?** Yes. ask joins lemlist to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. lemlist maps crm.company, which 227 other connectors also map. **Does actionlake keep my lemlist data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your lemlist credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like lemlist Shares the most action names with - [Instantly 22](https://actionlake.com/connectors/instantly) - [Reply.io 18](https://actionlake.com/connectors/reply-io) - [Copper 16](https://actionlake.com/connectors/copper) - [Salesloft 15](https://actionlake.com/connectors/salesloft) - [Zoho SalesIQ 13](https://actionlake.com/connectors/zoho-salesiq) - [Hunter.io 8](https://actionlake.com/connectors/hunter-io) Joins with, on shared entities - [Simpro 3](https://actionlake.com/connectors/simpro) - [Acumatica Cloud ERP 3](https://actionlake.com/connectors/acumatica-cloud-erp) - [Odoo 3](https://actionlake.com/connectors/odoo) - [Unified.to 3](https://actionlake.com/connectors/unified-to) - [Zoho Desk 3](https://actionlake.com/connectors/zoho-desk) - [ERPNext (Frappe) 3](https://actionlake.com/connectors/erpnext-frappe) Browse - [All CRM & sales connectors](https://actionlake.com/connectors/category/crm-and-sales) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
