There are four types of error pages you can configure:
Say your product pops up an error code. You can be extra helpful, and easily link from that error code to a documentation page with tips for resolving that error.
Add an error code link to a doc page by selecting the page in your project dashboard, then selecting API Error in the page type dropdown at the top left.
You can create custom error pages to display to your users if they try, for example, to access a broken link. Found under Configuration > Error Pages.
We show our generic 404 page by default when a customer tries to access a broken link
Use a Custom Page as your 404 message instead for a look that better represents your brand.
You can also set up 301 redirects if there is no matching ReadMe page. We'll check it to see if there's a redirect rule for the URL. You can use this to redirect your old non-ReadMe paths to your new site when migrating to ReadMe. Use the format "oldurl -> newurl" (for example, "/documentation/test -> /docs/test"), with one per line. You must redirect from relative paths (i.e., paths that start with a "/" and that come after the main site domain).
Here's some examples:
/docs/top-feature-requests -> /docs/feature-requests /docs/getting-started -> /docs/get-started /docs/ios-sdk -> http://github.com/company/ios-sdk /google -> http://google.com /old/([a-z]*) -> /new/$1 \w* -> /custom-error-page
Update (June 2020)
When changing the slug of a Readme page, there is no need to set up a redirect. Readme takes care of it 'behind the scenes'.
Cannot redirect from hash url
It is not possible to redirect from a hash URL like https://readme.readme.io/v2.0/reference#api-specification but it is possible to redirect to a hashed URL
$1 (or 2, 3, etc).
If you your URL includes symbols, remember to escape them using the backslash
If you want a catch-all, use
- Browsers cache these redirects, so changes might not work immediately.
- Regexes must be a complete match, not a partial match. You can't use
$, because they're appended automatically.
- Redirects are tested in order they're written, and the first match is used.
- Redirects are for 404 pages only, if the page exists, it will not redirect.
This feature is only available for the Business and Enterprise plans.
