A program gateway funding source represents a bank account from which funds are drawn for Gateway Just-in-Time (JIT) Funding transactions. For more information about JIT Funding, see [About Just-in-Time Funding](/developer-guides/about-jit-funding/). In a sandbox environment, you can create a program gateway funding source that simulates funds for use in test transactions. In a production environment, you must work with a Marqeta representative to define the bank account from which the program gateway funding source draws funds. **Note**\ If you are using a third-party service to collect user funds, Marqeta and the issuing bank require specific reporting to ensure compliance with applicable rules and regulations. Contact Marqeta for more information.

Create program gateway source

**Action:** `POST`\ **Endpoint:** `/fundingsources/programgateway` {/* */} Creates a program gateway funding source. A program gateway funding source is a transaction relay that allows you to approve or decline transactions in real time.

**Allowable Values:**

1–50 chars | | custom\_header

object

Optional | Additional custom information included in the HTTP header. For example, this might contain security information, along with Basic Authentication, when making a JIT Funding request. Custom headers also appear in the associated webhook’s notifications.

string

Optional | Unique identifier of the program gateway funding source. If you do not include a token, the system will generate one automatically. As this token is necessary for use in other calls, we recommend that you define a simple and easy to remember string rather than letting the system generate a token for you. This value cannot be updated.

**Allowable Values:**

1–36 chars | | url

boolean

Optional | Specifies whether or not to use mutual transport layer security (mTLS) authentication for the funding request.

mTLS authentication is in the beta testing phase, and is not yet generally available. Contact your Marqeta representative for more information about using mTLS authentication.

**Allowable Values:**

`true`, `false`

**Default value:**
`false` |
