The Best Salesforce Integrations and Apps in 2026
Salesforce is the system of record for your pipeline, but a CRM only earns its keep when it’s wired to the email, calendar, meetings, and billing tools where the actual work happens. The AppExchange marketplace lists roughly 6,200 apps from 3,600+ developers as of late 2025 — and Salesforce’s broader AgentExchange ecosystem now spans 10,000+ apps, 1,000+ pre-built agents, and 2,600 Slack apps — so the hard part isn’t finding an integration, it’s picking the few that matter.
Here are the Salesforce integrations actually worth setting up, grouped by what they do — and then the way to connect Salesforce to anything with an API.
Email: Gmail and Outlook via Einstein Activity Capture
- Einstein Activity Capture — Syncs your Gmail or Outlook account with Salesforce, automatically logging sent and received email and calendar events to the activity timeline of the related account, contact, lead, and opportunity. Included with Sales Cloud Enterprise Edition and above.
- Gmail and Outlook Integration (side panel) — The Salesforce panel that lives inside Gmail or Outlook so reps can see and update records without leaving the inbox, and log individual emails manually.
- A 2026 heads-up — Microsoft is retiring Exchange Web Services in October 2026, so if you run Einstein Activity Capture, Inbox, or the legacy Lightning Sync against Microsoft 365, migrate to the Microsoft Graph authentication method before then to avoid a sync outage.
Communication: Slack
- Slack for Salesforce — Salesforce owns Slack, so this is the deepest comms integration in the ecosystem. Push record alerts into channels, get notified when a deal changes stage, run Sales and Service workflows, and surface Salesforce data inside Slack conversations.
Meetings and calls: Zoom, Aircall, Dialpad
- Zoom — Log Zoom meetings against Salesforce records and schedule calls from a contact or opportunity.
- Aircall — Cloud phone system with click-to-dial, automatic call logging, and call recordings attached to the right Salesforce record.
- Dialpad — AI calling and voice with call transcripts and outcomes synced back to leads and contacts.
Marketing: Marketing Cloud, Pardot, and Mailchimp
- Marketing Cloud Account Engagement (Pardot) — Salesforce’s own B2B marketing automation, natively connected for lead scoring, nurture campaigns, and closed-loop reporting.
- Mailchimp — Sync Salesforce contacts and leads to Mailchimp audiences and pull campaign engagement back into the CRM.
- Google Ads and Meta lead ads — Route captured ad leads straight into Salesforce so follow-up starts without manual export.
Documents and e-signature: DocuSign, PandaDoc
- DocuSign — Generate, send, and track contracts for signature from an opportunity, with signed-status written back to the record.
- PandaDoc — Build quotes and proposals populated from Salesforce data and track when they’re opened and signed.
Accounting and payments: QuickBooks, Stripe
- QuickBooks — Sync accounts, invoices, and payment status between Salesforce and QuickBooks so sales and finance see the same numbers.
- Stripe — Surface subscription and payment data against Salesforce accounts for billing and revenue visibility.
No-code automation: Zapier and Make
- Zapier and Make — Connect Salesforce to thousands of other apps for basic field-mapping and record-creation triggers. They’re solid for “when a lead is created, add a row here” plumbing, but they move fields between apps — they don’t reason over the data or decide what should happen next.
The AI way to connect Salesforce to anything: Carly
Carly is an AI executive assistant that connects to 200+ tools — Salesforce included — and lets you bring your own API key to connect to anything else with a REST API. Instead of mapping one field to another, Carly reads what’s in Salesforce, decides what to do, and acts on it.
- Runs in the cloud and acts on triggers 24/7 — a new opportunity, a stage change, an inbound email — without you clicking anything.
- Reasons over your Salesforce data instead of just copying a field: it can read a deal’s history, draft a tailored follow-up, and update the record.
- Ties Salesforce to the rest of your stack — Gmail, Outlook, calendar, Slack, and your other CRM and billing tools — in a single workflow.
- Builds the whole workflow from a plain-English description, so you don’t touch Apex, flows, or a Zapier canvas.
Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited.
Carly also integrates with Salesforce.
How to connect Salesforce to a tool with no native integration
- In Salesforce, set up a Connected App (or an External Client App) with OAuth 2.0 enabled, and generate the credentials the REST API uses to authenticate.
- Paste those credentials into Carly on the integrations page.
- Describe the workflow you want in plain English — for example, “when an opportunity moves to Closed Won, create the invoice in our billing tool and post it to Slack” — and Carly builds and runs it.
Frequently Asked Questions
Does Salesforce have integrations?
Yes. Salesforce’s AppExchange marketplace lists roughly 6,200 apps as of late 2025, covering email, communication, marketing, documents, accounting, and more, plus native REST and Bulk APIs for custom connections.
What is the best Salesforce integration for automation?
For basic field-syncing, Zapier or Make work fine. For automation that reads your Salesforce data, decides what to do, and acts across email, calendar, and other tools, an AI agent like Carly does the reasoning that field-mapping tools can’t.
How do I connect Salesforce to an app that isn’t listed?
Create a Connected App in Salesforce with OAuth 2.0 to get REST API credentials, then paste them into a tool like Carly and describe the workflow you want in plain English.
How much does an AI automation for Salesforce cost?
Carly’s AI agents start at $35/month, and non-AI steps in a workflow run free and unlimited.

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."
