How to Verify Third-Party Integrations After Deploy in GitHub Actions

A release can be healthy on its own yet fail because a payment or email provider credential is wrong, so verify each critical integration after deploy.

Expose an integrations health endpoint that pings each external dependency, then verify it returns all-green after deploy, using sandbox modes where a real call would have side effects.

Steps

• Add an /integrations/health endpoint that checks each provider.
• Return per-integration status so a failure names the culprit.
• Verify all integrations report healthy after deploy.

Workflow

- name: Verify integrations
  env: { BASE: ${{ vars.DEPLOY_URL }} }
  run: |
    RESP=$(curl -sf "$BASE/integrations/health")
    echo "$RESP" | jq .
    BAD=$(echo "$RESP" | jq -r '.checks | to_entries[] | select(.value != "ok") | .key')
    if [ -n "$BAD" ]; then
      echo "unhealthy integrations: $BAD"; exit 1
    fi

Gotchas

• Use sandbox or ping endpoints so verification does not charge a card or send a real email.
• Distinguish a provider outage (retry) from a misconfiguration (fail and roll back).
