# Processing Flow Role Types ### Assignee role An **Assignee** is a role that fills in fields in the envelope or signs a document with an electronic signature when required. The **Assignee** role must have at least one field in at least one template document. The **Assignee** role must appear earlier in the flow than the **Signer** role. ### Signer role A **Signer** is a role that signs a document with an electronic signature. The **Signer** role must have at least one signature field in at least one template document. A **Signer** can’t have two signature fields in the same document. The **Signer** role must appear later in the flow than the **Assignee** role. ### Approver role An **Approver** can approve or reject moving the envelope to the next roles. The **Approver** role can be set at any point in the processing flow, but not earlier than the **Sender**. ### CC role A **CC** role receives a copy of the envelope and can’t edit document fields. The **CC** role can be set at any point in the processing flow, but not earlier than the **Sender**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
