Create a CNAME record pointing the custom subdomain to Spindl's redirect server (`custom-domains.spindl.click.)` 2. Create a TXT record for SSL certificate validation & creation (this is specific to each subdomain) | Record Type | Name | Value | | ----------- | --------------------- | -------------------------------- | | **CNAME** | link | `custom-domains.spindl.click.` | | **TXT** | \_acme-challenge.link | (We'll send it to you privately) | As an example, here is what this should look like in different providers: * Cloudflare (for the subdomain `l`)
* Namecheap (for the subdomain `link`)
After configuring records, it can take up to a few hours for the changes to propagate and the SSL certificate to be generated. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.spindl.xyz/spindl/features/short-links/custom-domains.md?ask=&goal= ``` `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.
