Use the Invoicing API to create, send, and manage invoices. You can also use the API or webhooks to track invoice payments. When you send an invoice to a customer, the invoice moves from draft to payable state. PayPal then emails the customer a link to the invoice on the PayPal website. Customers with a PayPal account can log in and pay the invoice with PayPal. Alternatively, customers can pay as . The API exposes 22 endpoints secured with oauth2 authentication.
Install Jentic One Beta
Connect the Invoices to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Invoices, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases
Patterns agents use Invoices API for, with concrete tasks.
★ Payments Operations
Use the Invoices to perform payments operations programmatically. The API provides 22 endpoints covering core functionality including create draft invoice, list invoices, send invoice.
Call POST /v2/invoicing/invoices to create draft invoice
Automated invoices Management
Automate invoices operations by combining multiple Invoices endpoints. Agents can list invoices and then send invoice in a single workflow.
Call GET /v2/invoicing/invoices to list invoices, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Invoices endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle oauth2 tokens manually.
Search Jentic for 'create draft invoice', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Invoices oauth2 credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'create draft invoice') and Jentic returns the matching Invoices operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Invoices integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using Invoices API through Jentic.
What authentication does the Invoices use?
The Invoices uses OAuth 2.0 for authorization. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I create draft invoice with the Invoices?
Yes. Use the POST /v2/invoicing/invoices endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Invoices?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I create draft invoice through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'create draft invoice'. Jentic returns the matching Invoices operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the Invoices have?
The Invoices exposes 22 endpoints covering invoices, search-invoices, templates operations.
