Manual Account Reconnection vs. Filter Code Adaptation for API Migrations

Choosing a Recovery Path for Deprecated Integrations

To minimize the risk of data loss and configuration errors in a complex environment, manual account reconnection is the superior approach. While it requires more initial effort, it ensures the integration is aligned with the current API version's authentication scopes and validated data shapes, providing a stable foundation that filter code cannot guarantee.

Analysis of Recovery Methods

The choice between these two paths depends on whether the failure is caused by an authentication break or a structural change in the data payload.

Factor	Manual Reconnection	Filter Code Adaptation
Primary Use Case	Invalidated tokens or deprecated endpoints.	Active endpoints with modified schemas.
Reliability	High; uses official API definitions.	Lower; prone to silent failures.
Configuration	Requires per-applet verification.	Maintains existing applet structure.
Risk	Potential for duplicate trigger events.	Fragile; breaks on minor API updates.

When Filter Code is a Viable Alternative

Filter code adaptation is only a viable alternative when the following specific conditions are met:

• Endpoint Persistence: The API endpoint is still active and responding, but the payload fields have been renamed or restructured.
• Low Criticality: The applet does not handle mission-critical data, as filter errors often fail silently in the activity log.
• Simple Mapping: The required change is a straightforward data transformation (e.g., mapping user_name to full_name) rather than a logic shift.

Recommended Implementation Steps

1. Verify Endpoint Status: Check the service provider's developer portal to confirm if the API version is deprecated (requires reconnection) or merely updated (potentially filterable).
2. Isolated Testing: If attempting filter code, apply it to a single non-critical applet first. Monitor the activity log for several cycles to ensure no silent failures occur.
3. Trial Reconnection: If reconnecting, perform a trial on one account to determine if the service provider resets trigger identities, which would necessitate a cleanup of duplicate events.
4. Full Migration: Once the method is verified, roll out the change across the remaining interdependent applets.

Diagnostic Detail Needed: Does the service provider's documentation indicate that the API update included a change in OAuth scopes? If scopes have changed, filter code is impossible, and manual reconnection is the only path.
