Has anyone enabled API Access Control in an org with extensive integrations? I'd love to hear about pitfalls and things to know as we enable this. I'm aware of how it affects connected apps and how to manage those settings. I'm looking for gotchas and issues that may not be apparent from the documentation.
Great question! API Access Control (part of Salesforce Shield) is powerful but can definitely cause surprises when enabled in an org with existing integrations. Here are the key gotchas to watch out for:
1
. Named/Connected App Policies Must Be Configured Before Enforcement
W
hen you enable API Access Control, you move from "all Connected Apps are implicitly trusted" to "only explicitly approved Connected Apps can use specific APIs." If any integration uses a Connected App that hasn't been updated with an API Access Policy, those API calls will start failing immediately. Audit all Connected Apps in Setup before enabling.
2. JWT Bearer Flow and OAuth 2.0 Flows Are Impacted
A
P
I Access Control enforces policies at the OAuth token level. If integrations use JWT Bearer Token flows or user credentials-based flows, ensure the applicable Connected App has "API Access Control" Policies configured. Particularly watch out for Mulesoft, middleware, and ETL tool connections.
3. Managed Package Integrations Can Break Silently
I
nstalled managed packages (AppExchange apps) often use their own Connected Apps that you may not control directly. These can break without obvious error messages. Contact each ISV to understand their Connected App requirements before enabling.
4. IP Restrictions Layer on Top
If your org has IP restrictions on Connected Apps combined with API Access Control, the combination can create double-layered blocking that's hard to debug. Test in a sandbox with production-like Connected App configurations first.
5. Reporting and Audit Trails
Enable Event Monitoring (also part of Shield) alongside API Access Control to capture LoginEvent and ApiEvent data. This gives you visibility into what's failing after cutover, and helps quickly identify which Connected Apps need policy updates.
6. Sandboxes Inherit API Access Control Settings Partially
W
h
en you refresh sandboxes, API Access Control settings may not fully replicate. Verify in your sandbox that the behavior matches production before using it as a test environment.
Recommended approach: export all your Connected Apps, map them to their integration owners, and do a phased rollout by setting API Access Control to "Warn" mode (or enabling in a sandbox) before enforcing in production.
