The Best Streak Integrations and Apps in 2026
Streak is the CRM that lives inside Gmail — pipelines, contacts, and deals sit right in your inbox instead of a separate app you forget to open. That inbox-native design is Streak’s whole appeal, and it means the integrations that matter most are the Google tools you already use. But Streak’s ecosystem is smaller than a standalone CRM’s: outside of Google Workspace, it leans heavily on Zapier and its API to reach everything else.
Here are the Streak integrations actually worth setting up, grouped by what they do — and then the way to connect Streak to anything with an API, even when no native integration exists.
Google Workspace: Gmail, Calendar, Sheets, and Drive
This is Streak’s home turf. Because Streak runs inside Gmail, the Google integrations are the deepest and most useful ones you’ll set up.
- Gmail — Streak is a Gmail extension. Emails become part of your pipeline, with tracking, mail merge, snippets, and send-later built into the compose window.
- Google Calendar — see and schedule meetings tied to a deal without leaving your pipeline.
- Google Sheets — import and export pipeline data to Sheets for reporting and bulk edits.
- Google Drive — attach and reference Drive files directly on Streak boxes and contacts.
Scheduling and forms: Calendly, Google Forms, and Typeform
- Calendly — a native integration: when someone books a meeting, Streak can advance a stage or trigger the next step in your pipeline automatically.
- Google Forms and Typeform — capture inbound leads from a form straight into a Streak pipeline instead of copying responses by hand.
Communication: Slack
- Slack — install Streak for Slack from the App Directory to look up boxes, get pipeline updates, and run slash commands where your team already talks.
No-code automation: Zapier
- Zapier — this is how Streak reaches the other 9,000-plus apps it doesn’t integrate with natively. Simple triggers (“new box → do X”) cover a lot of ground, though Zapier is built for basic field-mapping, not for reasoning over your data.
Developer: the Streak API
- Streak REST API — for custom connections, Streak offers a developer-friendly API. You generate a key from the Streak sidebar in Gmail (Integrations → Custom Integrations → Create new key), and any pipeline you can access is available programmatically.
The AI way to connect Streak to anything: Carly
Streak’s native list is short by design — it’s Gmail plus a handful of Google and scheduling tools, and then Zapier for everything else. The moment you need Streak tied to a tool that isn’t on the list — or you want something smarter than “new box → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools and, crucially, lets you bring your own API key to connect to anything with a REST API — Streak included. It’s honest to say Carly is not a native Streak integration: it connects through your own Streak API key. In exchange you get an agent that:
- Acts on triggers, 24/7 in the cloud — when a box moves stages, an email lands, or a meeting is booked, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read the deal notes, draft a follow-up email in my voice, and log the next task.”
- Ties Streak to the rest of your stack — updating a pipeline becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, and tasks.
- Builds the workflow from a plain-English description — tell it “when a deal moves to Proposal Sent, wait three days and draft a nudge to the contact” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See the full Claude + Streak integration guide for how the API-key connection works, and the best AI CRM tools for where an AI layer fits alongside your CRM.
How to connect Streak to a tool with no native integration
- In Streak, generate an API key — open the Streak sidebar in Gmail, go to Integrations → Custom Integrations, and click Create new key.
- Paste your API key into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting Streak to whatever else you need, on triggers, without your laptop open.
Frequently Asked Questions
Does Streak have integrations?
Yes, though Streak’s ecosystem is Gmail-centric. It integrates natively with Gmail, Google Calendar, Google Sheets, Google Drive, Calendly, Google Forms, Typeform, and Slack, and it connects to thousands more apps through Zapier plus a REST API for custom connections.
What is the best Streak integration for automation?
For simple triggers, Zapier covers most apps. For automation that acts on triggers and reasons over your data — and to connect Streak to tools with no native integration — an AI agent like Carly connects via your Streak API key and runs workflows in the cloud.
How do I connect Streak to an app that isn’t listed?
Use Streak’s REST API. Generate an API key from the Streak sidebar in Gmail (Integrations → Custom Integrations), then hand it to a platform that supports bring-your-own-API-key connections — Carly does this and can wire Streak to any tool with an API.
How much does an AI automation for Streak cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Your Streak plan and API access are separate.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
