Create a bulk payment

Create a request for paying multiple bills. You can pay up to 200 bills with one POST /v3/payments/bulk request.

Bulk payments at BILL follow a set of rules.

• Successful response: In your bulk payment request, all your bill payments must be successful for a successful response. If any bill payment is not successful, the entire request fails and none of the bills in the request are paid.
• You can pay multiple vendors: You can pay multiple vendors with one POST /v3/payments/bulk request. In this case, make sure that you do not set vendorId in your request.
• You can only pay existing bills: When you create a single payment with POST /v3/payments, you can set createBill as true in your request for creating a new bill for a vendor payment. In your bulk payment request, an existing billId is required for each bill to be paid.
