An integration fails after a permission change
Sample incident
Impact: Sample integration cannot read device records. Scope: One simulated integration. Environment: Synthetic HTTP service
Stage 1 (sample sequence): Scope the failure
The report says the integration stopped after a configuration change.
- hypothesis
- Permission mismatch rather than a broad outage.
- test
- Inspect status and error before retrying.
- result
- 403 insufficient_scope narrows the investigation.
- decision
- Check the token permission configuration.

Thanks for flagging this. I can see the integration stopped after the change. I'll start with the failing request and who's affected. Please don't send token values, just the status code and the error with anything sensitive removed. I'll update you after I've checked the configuration.
Purpose: Acknowledge the problem and say when the next update is coming.
Stage 2 (sample sequence): Test the configuration
Inspect configured and required permissions.
- hypothesis
- The token no longer permits the requested operation.
- test
- Compare configured scopes with the response requirement.
- result
- Only profile.read is configured.
- decision
- Have an authorized admin restore only the permission that's needed, then test again.

SAMPLE DATA Configured token: scope=profile.read Required scope: devices.read
Escalation decision: A clear configuration mismatch like this doesn't need engineering yet. If it still fails with the right scope, escalate.. Evidence: response, token-config.

The request authenticates, but the token is missing devices.read. Right now it only has profile.read. We need an authorized admin to add devices.read back, and nothing broader than that.
Purpose: Explain evidence, next action and escalation conditions.
Stage 3 (sample sequence): Validate the recovery
Check the operation after an authorized configuration correction.
- hypothesis
- Correct permission restores the read operation.
- test
- Repeat the same request with the corrected token.
- result
- The sample response is 200 OK.
- decision
- Confirm the customer workflow and document the scope requirement.

The same request works now that the scope is fixed. Can you check the integration is running normally on your side? The cause was the scope mismatch, so retrying on its own wouldn't have fixed it.
Purpose: Make clear the fix was the configuration, not a retry.
Resolution
Sample integration is validated after the permission correction.
Root cause: Missing devices.read scope in the sample configuration.
Lessons and documentation
- Read the error before retrying.
- Use the smallest necessary permission.
- Validate the original operation.
