Field Identifier

A Field Identifier is a unique label assigned to a field, making it easy to reference that field via the Xodo Sign API. If you don't assign one, Xodo Sign auto-generates an identifier automatically.

How to assign a Field Identifier

1. In the Document Editor, select the field you want to label.
2. Right-click the field and select Field Identifier.
3. Enter your desired identifier name.

Best practices

• Use descriptive identifiers — Names like signerpaysignature or datefield1 make debugging easier.
• Field identifiers are case-sensitive — They must match exactly in API requests. Always preserve the original casing.
• Set identifiers when creating templates via the API — Use the identifier property when defining fields:

"identifier": "firstpersonsignature",
"name": "Signature"
