Legacy (v2) API documentation: https://app.resolvepay.com/docs/api/v2
The Resolve API is organized around REST principles. It uses predictable resource-oriented URLs, standard HTTP verbs and response codes, and accepts and returns JSON-encoded request and response bodies.
The current version is V5. You can upgrade the version of the API that your account uses within your merchant settings. Legacy (v2) API documentation may be found here.
The invoice represents the business transaction between you and your customer. In Resolve, an invoice must be tied to a customer and an advance can be taken on the invoice.
For an advance to be taken on the invoice, a PDF of the invoice must be uploaded and the associated customer must be approved and have available credit for the amount of the invoice.
A customer represents a company that you do business with. For larger companies, there may be several users with access to the customer account that can make purchases with their credit line. For smaller companies, a customer may represent a single individual. Retrieve a customer to get a summary of their total credit line and available credit balance.
A charge represents an agreement by the customer to accept credit terms for a transaction. It consists of a charge amount, term length (i.e. 30, 60, 90), and reference to the merchant's original order or purchase order numbers.
These endpoints are intended for merchants using the Checkout SDK. If you are not using the Checkout SDK flow, these endpoints are generally not needed.
Payout Transactions are the individual transactions like customer payments, Resolve advances, forwarded payments, etc. that are rolled into a Payout. Each Payout is the sum of one or more transactions. Note that certain fields are only relevant to certain transaction types - e.g.: a Payout Transaction of type monthly_fee will have both customer_id and invoice_id set to null.
A payment represents a transaction where a customer pays towards their invoices. When a payment is made to Resolve, the customer's available credit balance is increased by the amount of the payment. Payments can be made via various methods including ACH, credit card, check, or wire transfer. Each payment can be applied to one or more invoices.
A shipment represents the fulfillment of goods or services for an invoice. Track shipments to monitor delivery status and fulfillment progress. Shipments can be fulfilled through various methods including shipping providers, self-delivery, customer pickup, or for services-only transactions.
