# Update program transfer type

> Use this endpoint to update a program transfer type.

PUT/programtransfers/types/\{type\_token}

Use this endpoint to update a program transfer type. Include the `type_token` path parameter to indicate the program transfer type to update. Add the modified detail parameters to the body of the request in [JSON](http://www.json.org/) format. Only values of parameters in the request are modified; all others are left unchanged.

## URL path parameters

| Fields | Description |
| - | - |
| type\_token string  Required | Unique identifier of the program transfer type. **Allowable Values:**  Existing program transfer type token |

## Request body

| Fields | Description |
| - | - |
| memo string  Required | Memo or note describing the program transfer type. **Allowable Values:**  1–99 chars |
| program\_funding\_source\_token string  Required | Unique identifier of the program funding source to which program transfers will be credited. Send a `GET` request to `/fundingsources/program` to retrieve program funding source tokens. **Allowable Values:**  1–36 chars |
| tags string  Optional | Comma-delimited list of tags describing the program transfer type. **Allowable Values:**  1–255 chars |
| token string  Optional | Unique identifier of the program transfer type. If you do not include a token, the system will generate one automatically. This token is necessary for use in other API calls, so we recommend that rather than let the system generate one, you use a simple string that is easy to remember. This value cannot be updated. **Allowable Values:**  1–36 chars |
