Overview

Integrations

In short

What does Reply integrate with?

Reply has native two-way sync with four CRMs, published apps for Zapier and n8n, two visitor-identification sources, and a public API plus webhooks for everything else. Connecting a mailbox or a LinkedIn account is account setup rather than an integration and lives under How to.

Also connected, without a page of their own

Make – connects through Reply's public API. Follow Make's own Reply documentation; everything it does is available through the API.
Clay: two separate paths. For syncing data, set it up on the Clay side using Reply's public API and follow Clay's own documentation. Clay is also one of the tools the in-product assistant can connect to. See the section below.
Vidyard – video in email steps. Confirm current availability in the product before relying on it.

Tools the in-product assistant can connect to

Separately from the integrations above, Reply's in-product AI assistant can be connected to a catalogue of third-party tools so it can read and act in them on your behalf. Project trackers, several CRMs and a number of data providers are in that catalogue, and not every entry in it is available yet.

This is a different thing from an integration on this page, and it is worth being clear which one you want:

What you want to do	Where to go
Keep contacts and activity in step between Reply and another system, on a schedule	An integration on this page
Ask the assistant questions about another tool, or have it act there while it works	The assistant's connectors

A few tools appear in both places; Pipedrive and Clay among them. They are not the same connection and they do not share settings.

Setting up and managing the assistant's connectors is documented separately, at agents.reply.io.

Not integrations

Three things people look for here belong elsewhere, because they are account setup rather than connections between products:

What you want	Where it lives
Connect a mailbox – Gmail, Outlook, Microsoft 365, or any provider over SMTP and IMAP	Connect a mailbox
Connect a LinkedIn account, including Sales Navigator	Connect LinkedIn
Email warm-up	Why is warm-up not running?

Building your own

Where there is no native integration, there are three routes, in increasing order of effort:

Route	Good for
Zapier or n8n	Connecting to an app without writing code
Webhooks	Reacting to Reply events at volume, with the full payload
REST API	Anything else – the complete surface

An AI assistant can also work in your account directly through Reply's MCP server.

How CRM sync works

The mechanics are the same for every CRM: steps, directions, field mappings, filters and manual syncs. They are covered once, in Sync Reply with a CRM, rather than repeated on each page. Each integration page covers only what is specific to that tool.

Three things are true of every CRM integration and worth knowing before you choose one:

Contacts travel both ways. Activity does not. Emails, calls and tasks go from Reply to the CRM, never back.
Activity records are written once and are not updated afterwards.
No CRM syncs deals or opportunities as objects. Some can create or move them through triggers.

Common problems

Nothing has synced for hours – Why did my CRM sync stop?
One contact never arrived – Why did a contact not sync to my CRM?
No emails or calls in the CRM – Why is Reply activity not showing in my CRM?
A webhook never reached your endpoint – Why was a webhook not received?
