Test and go live with Invoicing

You can run negative tests on your integration to manage the responses you give to your customers.

Know before you code

• Before you trigger a simulation, you'll need to get an access token.

• Use Postman to explore and test PayPal APIs.

Simulation methods

To trigger a simulation for the Invoicing API, you can use a JSON pointer in the request payload or a path parameter in the request URI.

Test values are case sensitive.
