2.  **Check Data Processing:** Ensure your code isn’t altering or truncating the IDs.

**Resolution:** Adjust your integration to enforce proper ID formatting and validate IDs before using them in API calls.

### I’m seeing errors about "Insufficient access rights on cross-reference id." How do I resolve this?

1.  **Review User Permissions:** Check that your integration user has access to the required objects and fields.
2.  **Inspect Sharing Settings:** Validate that sharing rules allow access to the referenced records.
3.  **Confirm Data Integrity:** Ensure the related records exist and are accessible.

**Resolution:** Update user permissions and sharing settings to ensure all referenced data is accessible.

### Should I use REST or SOAP APIs for my integration?

1.  **Define Your Requirements:** Identify whether you need simple CRUD operations (REST) or complex, formal transactions (SOAP).
2.  **Prototype Both Approaches:** Build small tests with each API to compare performance and ease of use.
3.  **Review Documentation:** Consult Salesforce best practices for guidance.

**Resolution:** Choose REST for lightweight web/mobile applications and SOAP for enterprise-level integrations that require robust transaction support.

### How do I leverage the Bulk API in my Java application?
