When setting up the testing of a provider you will also need to setup the management of these provider states. The Pact verifier does this by making additional HTTP requests to the

--provider-states-setup-url

you provide. This URL could be on the provider application or a separate one. Some strategies for managing state include: • Having endpoints in your application that are not active in production that create and delete your datastore state • A separate application that has access to the same datastore to create and delete, like a separate App Engine module or Docker container pointing to the same datastore • A standalone application that can start and stop the other server with different datastore states So, TL;DR - you need to register a new route e.g.

/_pact/provider-states

that will receive requests from Pact during verification. In that route, you should do what is needed to setup the state

Hmm, so in this step I must implement an endpoint that returns the response registered in my contract that is stored in my Pact Broker? When I changed the provider-base-url to localhost:80 I didn't get this error, Is there an explanation for this situation? In this port, It's running an API with Docker.

Correct

I am confused about how to implement and endpoint if I decide to change my base provider url in the code, But I think I understand for now. ahshashas
