Agentforce Actions Guide (2026): Native Flows vs. MuleSoft vs. External Services
Source: Dev.to
Overview
Salesforce’s Agentforce runs on the Atlas Reasoning Engine, operating in a reason → act → observe loop to complete real business work—not just answer questions. If your agent lives entirely inside Salesforce (updating an Opportunity, querying Data Cloud), you can ship fast.
Most deployments stall when the agent needs to interact with the rest of your stack—post to Slack, update Jira/Linear, check a GitHub PR, schedule a meeting, or create a PagerDuty incident. That’s where “Actions” become the bottleneck.
Salesforce documentation points you toward Flow HTTP Callouts, the Standard Actions library, or MuleSoft. Each presents significant trade‑offs for engineering teams trying to move fast without breaking the bank or their security posture.
What Is an Agentforce “Action”?
An Agentforce Action is a callable tool that the Atlas engine can invoke to execute a step in its plan. Actions run either:
- Within Salesforce – native operations (e.g., updating a record).
- In external systems – via External Services actions generated from OpenAPI specifications.
Reasoning is only helpful if the agent can reliably execute actions, securely and with the proper permissions, across your SaaS ecosystem.
Key Takeaways
| Issue | Insight |
|---|---|
| Bottleneck | Agentforce can reason, but deployments fail when agents can’t reliably execute external actions. |
| Native trade‑offs | Flow HTTP Callouts + per‑user Named Credentials add ongoing auth/admin burden; schema changes can break flows. |
| Coverage gaps | Standard Actions and connectors rarely cover the long tail or deep endpoints. |
| Best pattern | Curated OpenAPI specs imported into External Services create discoverable Agentforce actions without brittle glue code. |
| The Solution | Composio acts as a bridge, generating secure, OpenAPI‑compliant connectors that import directly into Salesforce as Actions. |
| The Result | Deploy deeply integrated agents in days, accessing the “long tail” of SaaS tools with user‑level security strictly enforced. |
The Agentforce Actions Bottleneck (Why Most Deployments Stall)
The Atlas engine uses a sophisticated reasoning loop:
- Reason – evaluate a user query.
- Plan – devise a path to answer.
- Act – look for tools (Actions) to execute that plan.
If the agent lives entirely within the CRM (updating Opportunities or querying Data Cloud), you’re fine.
Friction arises when business logic bleeds outside Salesforce. A Sales Agent is useless if it can’t schedule a Google Calendar meeting; a Support Agent fails if it can’t check a Linear ticket status.
Three Common Choices to Bridge the “Actions Gap”
| Approach | Description |
|---|---|
| Flow HTTP Callouts / Apex | Quick to start but quickly becomes brittle and hard to manage at scale. |
| Standard Actions / MuleSoft | Offers breadth or depth, but often sacrifices velocity or requires heavy governance. |
| Generic iPaaS | Provides system‑level connectivity but lacks per‑user security context. |
Each of these patterns often fails to meet Agentforce’s specific needs.
Agentforce Integration Options Compared
| Option | Time‑to‑Ship | Long‑Tail Breadth | Endpoint Depth | Per‑User Security | Operational Burden | Typical Failure Mode |
|---|---|---|---|---|---|---|
| Flow HTTP Callouts + Apex | Medium | High (DIY) | High (DIY) | Possible (hard) | High | Schema‑mapping breaks; auth sprawl |
| Standard Actions library | Fast | Low‑Medium | Low‑Medium | Depends | Low | Missing endpoint or workflow nuance |
| MuleSoft | Slow‑Medium | Medium | Medium‑High | Strong (if designed) | Medium‑High | Overkill for long‑tail; slow iteration |
| Generic iPaaS (system key) | Fast | High | Medium | Weak | Medium | “System user” data‑leakage risk |
| Curated OpenAPI → External Services (Composio) | Fast | High | High | Strong | Low‑Medium | Mis‑scoped actions or governance gaps |
Why Standard Integration Patterns Fail Agentforce
1. Flow HTTP Callouts & Apex (The Management Trap)
Salesforce has improved here: you can use Named Credentials for OAuth handshakes and Flow HTTP Callouts for no‑code integration. This works well for simple, system‑to‑system connections.
The Friction
| Issue | Why it matters |
|---|---|
| User Context | Agentforce must act as the user (e.g., “Post to Slack as Sarah”). Achieving this natively requires a per‑user Named Credential, meaning you must set up individual Auth Providers and manage granular scopes for every external tool. Scaling this is painful. |
| Schema Complexity | Modern APIs (Jira, GitHub) return massive, nested JSON. Flow HTTP Callouts often choke on these schemas. |
| Maintenance | You still manually map inputs/outputs. If the external API changes, your Flow breaks and the agent fails. |
2. Standard Actions & MuleSoft (Breadth vs. Depth vs. Velocity)
Salesforce is rapidly building a library of “Standard Actions” for major platforms (Jira, ServiceNow, etc.). If the standard action does exactly what you need, use it.
The Reality
- Breadth Gap (Long Tail) – Most orgs use 50 + tools (Linear, Notion, PagerDuty, Brex, Asana, …). Salesforce won’t build native connectors for all of them. Spinning up a MuleSoft project for these long‑tail apps kills velocity.
- Depth Gap – Standard connectors expose only the top ~10 % of API endpoints (e.g., “Create Ticket”). If your agent needs to “Update a Custom Field” or “Fetch Transition History,” and that endpoint isn’t exposed, you’re back to square one: building it yourself.
3. Generic iPaaS (System‑Key Integration)
Many teams turn to a generic iPaaS and connect using a single system user. This gives fast, high‑breadth connectivity, but:
| Concern | Impact |
|---|---|
| Security Context | Actions run under a system account, losing per‑user provenance. |
| Data Leakage Risk | Users can inadvertently act on data they shouldn’t have access to. |
The Composio Solution
Composio generates secure, OpenAPI‑compliant connectors that import directly into Salesforce as External Services actions.
- Curated OpenAPI specs → Imported as discoverable actions.
- Per‑user security enforced via Named Credentials automatically.
- Low operational burden – No custom Apex, no brittle Flow mappings.
Result
- Deploy deeply integrated agents in days.
- Access the “long tail” of SaaS tools with user‑level security strictly enforced.
- Reduce maintenance overhead and accelerate iteration.
TL;DR
| Need | Best Fit |
|---|---|
| Fast, per‑user, secure external actions | Curated OpenAPI → External Services (Composio) |
| Simple system‑to‑system calls, low volume | Flow HTTP Callouts + Named Credentials |
| Enterprise‑grade integration with heavy governance | MuleSoft |
| Quick, high‑breadth connectivity without per‑user context | Generic iPaaS (system key) |
By moving from brittle, admin‑heavy patterns to Composio‑driven External Services, you eliminate the primary bottleneck that stalls most Agentforce deployments and unlock rapid, secure, long‑tail SaaS integration.
Security Gap (The Context Problem)
This is the most critical failure point of generic iPaaS tools (e.g., Zapier). These tools typically rely on a “System User”—one API key that governs all access.
The Risk
Imagine an intern asks the Agent, “What are the Q3 strategic risks?”
The Agent, reasoning that it needs to check documentation, uses a System Key for Google Drive to search for “Risks.” Because the System Key has admin access, the Agent pulls a confidential M&A document that the intern should never see.
The Requirement
You need strict user‑level OAuth. The agent must act as the user, respecting each user’s specific permissions in the external tool.
The Composio Approach: Managed Actions for Agentforce
Composio solves the “hands‑off” problem by providing a specialized integration layer for AI agents. It doesn’t replace your MuleSoft backbone; it handles the agile, long‑tail SaaS connections that your agents need now, with 100 % API coverage.
- Maps Salesforce users to external identities.
- Generates standard OpenAPI specifications that Salesforce natively supports.
The Workflow
- Connect & Curate – A developer selects the tools (e.g., GitHub, Slack) and chooses which actions to expose.
- Export – Composio generates a curated, strictly‑typed OpenAPI spec optimized for Salesforce limits, avoiding “spec bloat” errors.
- Import – The developer imports the optimized spec into Salesforce External Services.
- Deploy – Agentforce immediately recognizes these new endpoints as Actions available to the Atlas Engine.
No more wrestling with Flow JSON parsers or configuring Auth Providers—just import the capabilities.
Deep Dive: The “Deal Room” Workflow
Scenario: A Sales Rep tells the agent:
“Update the Acme deal stage and notify the solutions team channel.”
| Step | Description |
|---|---|
| 1. Reasoning (The Brain) | Atlas identifies two tasks: update a Salesforce object and send a Slack message. |
| 2. Data Access (Internal) | Agent uses standard Salesforce permissions to update the Opportunity record. |
| 3. External Action (The Hands) | Agent calls the Composio_Slack_PostMessage action defined in External Services. |
| 4. Authentication (The Passthrough) | Request routes through Composio, which injects the initiating user’s OAuth credentials into the header. |
| 5. Zero‑Data Retention | Payload passes through an encrypted tunnel without being stored in Composio’s databases (SOC 2, zero‑knowledge). |
| 6. Observation | Composio returns a success flag or structured error; Atlas confirms the action to the user. |
Note on data handling: Enterprises can configure logging/retention. Composio supports SOC 2 controls and can minimize or avoid payload logging per policy.
Why “User‑Level” Auth Is Non‑Negotiable
In an autonomous‑agent world, least privilege is the only defense against data leaks. When you use “System” credentials (common in generic integrations), you bypass the security controls of your external SaaS tools.
Composio creates a 1:1 mapping between the Salesforce user and the external‑tool identity, ensuring the agent never defaults to “superuser.” You can confidently deploy agents that interact with sensitive systems like Jira, GitHub, or HRIS platforms, knowing they can’t exceed the permissions of the human commanding them.
Agentforce Actions Deployment Checklist (Production‑Ready)
| ✅ | Item | Details |
|---|---|---|
| 1 | Choose identity model | Default to per‑user authentication for least‑privilege access. |
| 2 | Define an action allow‑list | Expose only the actions your agent needs (principle of minimal capability). |
| 3 | Use a curated OpenAPI spec | Prefer a typed, minimal, importer‑friendly spec. Avoid massive, raw API definitions. |
| 4 | Validate schema & limits | Ensure request/response shapes won’t break your runtime (e.g., large nested objects, optional fields, pagination). |
| 5 | Add policy controls | Include logging/retention, audit trails, environment separation, and secrets handling that meet security requirements. |
| 6 | Fail safely | Return structured error messages so Atlas can recover (e.g., ask for missing fields, retry, or escalate). |
| 7 | Measure cost & reliability | Track action success rate, retries, and timeouts. Since actions are metered, reliability directly impacts ROI. |
How to Use
- Review each item before promoting actions to production.
- Mark the check‑boxes as you confirm compliance.
- Re‑run the checklist after any change to the action definitions or deployment environment.
Conclusion
Agentforce represents the future of CRM, but connectivity constraints limit its potential. The Atlas Reasoning Engine is ready to run, yet it still needs the right tools to execute effectively.
- Don’t let agents fail because of schema errors in Flow.
- Avoid waiting weeks for a MuleSoft connector.
- Prevent dead ends when a standard action lacks the specific API endpoint you need.

Frequently Asked Questions
Does Composio store my data?
No. Composio operates as a pass‑through execution layer. Authentication tokens are encrypted at rest, but we don’t store the action payloads (inputs or outputs) your agents execute. Logs can be configured for zero‑knowledge, ensuring compliance with strict data‑residency and privacy requirements (SOC 2).
Why do I need Composio?
- Provide user‑level OAuth for every external call.
- Generate curated OpenAPI specs that import cleanly into Salesforce External Services.
- Act as a secure, zero‑knowledge pass‑through, eliminating the need for custom middleware or “system” credentials.
- Offer fine‑grained policy controls (logging, retention, audit trails) that meet enterprise security standards.
Does Salesforce Have Standard Actions?
Standard Actions work well for everyday use cases on major platforms (e.g., “Create Jira Ticket”). They fall short when you need to:
- Access the “Long Tail” of apps (Notion, Linear, PagerDuty, etc.).
- Perform deep operations, such as hitting a specific, non‑standard API endpoint in Jira.
Composio solves these limitations by providing connectors for hundreds of apps and exposing the entire API surface—not just the most common actions.
How Does Composio Connect to Salesforce Agentforce?
- Export the standard OpenAPI specifications from Composio.
- Import those specifications into Salesforce External Services.
- Salesforce generates native Actions, which the Agentforce Atlas Engine can discover and use immediately.
Does This Consume Salesforce Flex Credits?
Yes. Action execution consumes Flex Credits like any other action. Because Composio connectors are maintained and strictly typed, you avoid wasted credits on failed calls or “hallucinated” parameters that often occur with brittle home‑grown integrations.
