What each call really does - Groovin

There is no test mode. The API, the playground on these pages and your AI assistant all act on your real LinkedIn account and your real CRM.

The Level column tells you how careful to be:

Info: safe to try.
Warning: changes nothing, but uses a limited LinkedIn action, or cannot be undone.
Danger: changes something real, on LinkedIn or in your CRM.

These limits belong to your LinkedIn account, so the API, the MCP and the extension all share them. See Limits and quotas.

LinkedIn

Action	Level	LinkedIn	Your CRM	Before you repeat it
List the people in your conversations	Info	None: reads a server-side copy of your inbox	None	Safe to repeat.
Read a conversation	Info	None: reads a server-side copy of your inbox	None	Safe to repeat.
Mark a conversation as read or unread	Danger	Live write: may send a read receipt	None	Safe to repeat. LinkedIn may refuse marking as unread.
Get a LinkedIn profile	Warning	Live read: a profile view the person may see	None	Each repeat is another profile view: wait before trying again.
Send a LinkedIn message	Danger	Sends a real message. Can also cost 1 live profile view	Recorded automatically by the message sync. With your auto-create preference on, it can also create a contact, turn on sync, import the history and spend an email credit	Never repeat blindly. After a timeout, a 5xx or no answer at all, the message may have gone out. Wait a few minutes, check the chat, and only then try once. About 100 messages a day.
Send a LinkedIn invitation	Danger	Sends a real invitation. Can also cost 1 live profile view	Updates a linked contact and can add a note. With your auto-create preference on, it can also create a contact, turn on sync, import the history and spend an email credit	Never repeat blindly. After a timeout, a 5xx or no answer at all, the invitation may have gone out. Wait a few minutes, check the pending invitations, and only then try once. About 80 to 100 invitations a day, 200 a week.
List your LinkedIn connections	Warning	Live read: 1 request per 1,000 connections, stopping early with `limit` or `connected_after`	None	Each repeat costs LinkedIn requests: wait before trying again. An empty request reads your whole network.
List your pending invitations	Warning	Live read: 1 request per 100 invitations, always the whole list	None	Each repeat costs LinkedIn requests: wait before trying again. `limit` does not reduce the cost.

CRM contacts and companies

Action	Level	LinkedIn	Your CRM	Before you repeat it
Check who is already in your CRM	Info	None	Live search on Attio and HubSpot, using your CRM’s API quota	Safe to repeat.
Create CRM contacts	Danger	A live profile read unless you pass `profile`. On Attio, a live company page read can still happen. With sync on: live reads and a history import	Creates or links contacts and companies, with lists and notes	Not always safe. If the CRM search fails, or a first batch is still running, a resend can create duplicates. Check who already exists, then resend only the failed people. 1 email credit per email found on a new Attio contact. A full batch can take several minutes.
List your synced contacts	Info	None	None by default. With `include_crm_details`: 1 read per contact	Safe to repeat.
Turn message sync on or off	Danger	On: live network lists once per batch, up to 10 profile lookups, and an inbox refresh. Off: none, unless you send URLs	On: properties, notes, chat history. Off: deletes conversation notes	Safe: the contact ends up in the state you asked for. Wait several minutes between On batches. Off: a note that failed to delete stays in your CRM, and repeating will not remove it.
Find missing LinkedIn URLs	Danger	Live reads, within daily limits	Fills empty LinkedIn URL fields only	Resend only what is in `not_processed`, never the whole list. A second batch at the same time answers 409. 1 credit per URL found, 500 credits a month.
Find missing company domains	Danger	None	Fills empty domain fields only, and only with `crm_company_id`. Can save the company’s LinkedIn page with it	Resend only what is in `not_processed`. A repeated lookup that finds a domain spends a credit again, even by name only. 1 credit per domain delivered. Credits do not refill.

LinkedIn connections import

Action	Level	LinkedIn	Your CRM	Before you repeat it
Start a connections import	Danger	None: it only reads your file	Real run: bulk creates and updates. Preview: reads only	Do not resend blindly: check the import status first. Preview and real run email you. A real run spends 1 domain credit per domain found.
Check a connections import	Info	None	None, but a stalled real run can resume and keep writing	Safe to repeat: wait for `poll_after_seconds` between calls.
Stop a connections import	Warning	None	Stops further writes, undoes nothing	Check the import status first: the stop may already be recorded. Sends the end-of-import email.
