8. Publish your consumer contract to API Hub for Contract Testing

Now that we have created our consumer contract, we need to share it to our provider. This is where API Hub for Contract Testing comes into the picture. This step is referred to as "publishing" the consumer contract.

Publish the consumer build locally

As per step 4, we're going to need credentials to our API Hub for Contract Testing account here:

  1. Go to API Hub for Contract Testing and copy your read/write API Token

  2. Export these two environment variables into the terminal, being careful to replace the placeholders with your own values:

    export PACT_BROKER_BASE_URL=https://YOUR_PACTFLOW_SUBDOMAIN.pactflow.io
export PACT_BROKER_TOKEN=YOUR_API_TOKEN

  3. npm run publish

  4. Go to your API Hub for Contract Testing dashboard and check that a new contract has appeared

Expected state by the end of this step

  • There should be a contract published in your API Hub for Contract Testing account before moving on.

Publish the consumer build in Github Actions

In Github:

  1. Open your forked example-bi-directional-consumer-<tool> project (https://github.com/<your-username>/example-bi-directional-consumer-<tool>)

  2. Click on the Actions tab.

  3. Click the button with the text "I understand my workflows, go ahead and enable them."

  4. Under the Workflows menu on the left, select Build.

  5. You will see the text This workflow has a workflow_dispatch event trigger. To the right of that text is a button with the label Run workflow. Click the button.

  6. Leave the branch as master and click the green Run workflow button.

❌ The build will fail with an authentication error when it tries to publish the pact - that's expected. We need to update the configuration to point it at your new API Hub for Contract Testing account.

Expected state by the end of this step

  • The consumer build fails with authentication errors, don't worry, we will address this in the next step ❌.
