Enforce Unique Values with Unique Fields

If a field should never have the same value twice across a custom object — a serial number, a reference code, an ID — mark it as unique, and Vendi Today will stop duplicates before they happen.

Setting a field as unique

On a new or existing field:

1. Go to Settings → Custom Fields.
2. Click Add Field (or edit an existing one).
3. Choose a supported type: Single Line Text, Multi Line Text, Number, or Phone.
4. Check Mark Field as Unique.
5. Save.

On the primary field when creating the object:

1. Go to Settings → Objects → Add Custom Object.
2. Define the primary field.
3. Check Mark Primary Field as Unique.
4. Create the object.

What happens with a duplicate value

• On the primary field: the save is blocked outright.
• On a non-primary unique field: duplicate rows are skipped with a warning.
• During a CSV import: the import completes, but rows with a duplicate value fail and are flagged.
• Through the API: a duplicate value returns a validation error.

Where this is enforced

Uniqueness applies everywhere a record can be created or updated, enforced per account, with a maximum of 10 unique fields per object.

Something to keep in mind

Once you turn a unique field back to non-unique, you can't re-enable uniqueness on it later.
