### Create Signer

**Slug:** `ESIGNATURES_IO_CREATE_SIGNER`

Add a signer to an existing contract/signature request. This action queues the addition of a new signer to a contract that has already been created.

Use this when you need to add additional signers to a contract after it has been created, or when you want to add signers incrementally rather than all at once during contract creation. Note: The API returns a queued status, indicating the operation has been accepted for processing. Adding a new signer does not automatically send an email notification unless the contract settings are configured to do so.

| `custom_fields` | object | No | Custom metadata key-value pairs to attach to the signer for tracking or integration purposes |
