# Go-live checklist

Use this checklist to take your integration live.

- [ ] Simulate scenarios

There are some common paths you should make sure your integration handles successfully, for example, a customer cancelling their mandate or a payment failing due to lack of funds. We’ve created [scenario simulators](https://developer.gocardless.com/developer-tools/scenario-simulators) and provide test [bank details](https://developer.gocardless.com/resources/test-bank-details) you can use to replicate various states and responses.

- [ ] Set up your live account

[Go here](https://manage.gocardless.com/) to create your live GoCardless account. If you are working with a GoCardless Account Executive, they will help you with this step.

- [ ] Create a live access token

Just as you did with your sandbox account, navigate to the [Developers tab](https://manage.gocardless.com/developers), then select Create followed by Create Access Token. Make sure the token has read/write permissions. Be sure to save it in a secure place or add it directly to your build.

- [ ] Create your payment pages

Create your Payment Pages in accordance with our compliance [guides](https://support.gocardless.com/hc/en-gb/articles/115004521925-Custom-Payment-Pages). This will need to be approved by a member of our Onboarding team. You can reach out to them here.

- [ ] Amend API endpoints from sandbox to live

You can easily update your existing integration to point to the live environment by changing the prefix of each endpoint from `https://api-sandbox.gocardless.com` to `https://api.gocardless.com`.

- [ ] Set up a webhook listener

If you have read our guidance on [Staying up to date with webhooks](https://developer.gocardless.com/getting-started/staying-up-to-date-with-webhooks), add the endpoint to your live account following the same steps you completed for sandbox. You can find the guidance linked here to refresh your memory.

- [ ] Test your connection

Check that you’re still able to successfully make a call to our API - choose a call that you’ve successfully tested in Sandbox.

- [ ] Subscribe to GoCardless API status updates

You can [subscribe to notifications](https://www.gocardless-status.com/) about the API for both sandbox and live environments. This helps you stay proactively aware of any scheduled maintenance or downtime.
