Use this section when you need troubleshooting material, error lookup, or support resources.

Start here when you need to:

* troubleshoot a failed API call
* check a known integration question or edge case
* find the right support or escalation path

### FAQ

#### Where should I start when something fails?

Start with [Error Codes](/api-document/support-and-reference/troubleshooting-and-support/errors-handing.md) when you have a returned status code.

Use [FAQs](/api-document/support-and-reference/troubleshooting-and-support/faqs.md) when the issue is about expected behavior, design choices, or common edge cases.

#### When should I use support resources?

Use support resources when error lookup and FAQs do not resolve the issue, or when the case needs operational follow-up beyond self-service troubleshooting.
