TL;DR

The ID in a lookup or reference field is malformed or belongs to the wrong object. Validate the ID format and confirm it points at the right object type.

Error

INVALID_CROSS_REFERENCE_KEY: invalid cross reference id

Steps

1. Check the ID's format and its object prefix Expected: you spot the wrong object or a typo.
2. Confirm the referenced record exists and you can see it Expected: it is real and visible.
3. Fix the lookup value to the correct ID Expected: the reference is valid.
4. Re-run the operation Expected: it succeeds.

When to use

• INVALIDCROSSREFERENCE_KEY
• A lookup points at a bad ID

When not to use

• The ID is fine (then check field-level security)
• The reference is polymorphic (then confirm the allowed types)

Tool compatibility

• Salesforce ID formats
• Data loader upserts

Variant phrasings

invalid cross reference id

The lookup ID is malformed or points at the wrong object.

INVALIDCROSSREFERENCE_KEY

Same: validate the ID and its object type.

Why it happens

Agents copy IDs between objects or truncate them. The three-character prefix encodes the object, so a wrong prefix fails fast.

Edge cases

• 15 vs 18 character IDs: both work in the API, but case matters for the 15-char form
• External IDs need the field marked as external first
