# Domain mismatch error

This error message appears when the domain set for your Calcumate integration doesn’t match the one your integration has been embedded onto. 

Commonly this is because of either a spelling mistake, or way our database reads your domain. 

Either way, there’s a simple solution:

1. Copy the URL that our error message has recommended.
2. Login to your Calcumate account [here](https://calcumate.co/login) and paste the URL in step 1 of the integration builder.
3. Continue through the steps and re-publish your integration code snippet.
4. Copy this new integration and use it to replace the existing code on your website.
5. Go to the right page and clear your cache before completing a hard refresh of your browser

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.calcumate.co/frequently-asked-questions/domain-mismatch-error.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
