    Custom Domains

    Last updated · MAR 2026·Read as Markdown

    Replace your-agent.app.avcodex.com with chat.yourintegrator.com, roomhelp.yourbrand.com, or whatever subdomain fits your brand. Custom domains make the agent feel like a native part of your integrator portal, your managed-services offering, or your client-facing room support.

    Note: Custom domains require a Builder plan or higher.
    Benefit Description
    Brand consistency Clients stay on your integrator's domain, not a third-party host
    Trust Programmers, end users, and procurement teams see a familiar URL
    Professionalism No platform branding in the URL when sharing with end-clients
    Cookies A subdomain of your main site keeps cookies same-site, which fixes cross-origin chat-history issues in iframe embeds

    Before setting up a custom domain:

    • Builder plan or higher subscription
    • Ownership or control of a domain name
    • Access to your domain's DNS settings
    • A published AVCodex agent

    1. Add the DNS Record First

    Before configuring inside AVCodex, add this CNAME record at your domain registrar:

    Type Name Value
    CNAME chat (or your subdomain) fallback.app.avcodex.com

    After you register the domain in AVCodex (Step 4), you'll also add a second DNS record for SSL validation. AVCodex will show you the exact record to add.

    Tip: Use a subdomain (like chat. or roomhelp.) rather than your root domain. Keeps your main website separate, simplifies DNS, and avoids interfering with email or other services on the apex domain.

    2. Open Settings

    Go to your agent's Settings page. You'll see the Custom Domain card.

    3. Enter Your Domain

    Type your subdomain in the input field:

    code
    chat.yourintegrator.com

    Do not include https:// or www..

    4. Click Add

    AVCodex verifies your DNS configuration. If the CNAME record is found and points to fallback.app.avcodex.com, your domain is added.

    After registration, AVCodex shows a second DNS record needed for SSL validation. Add this record at your registrar to activate HTTPS.

    Cloudflare#

    1. Go to your domain's DNS settings.
    2. Click Add Record.
    3. Select CNAME.
    4. Name: your subdomain (e.g. chat).
    5. Target: fallback.app.avcodex.com.
    6. Proxy status: DNS only (gray cloud).
    Warning: Disable Cloudflare's proxy (orange cloud) for the subdomain. Use "DNS only" mode. Custom domains will not provision SSL behind Cloudflare's proxy.

    GoDaddy#

    1. Go to My Products > DNS.
    2. Click Add under Records.
    3. Type: CNAME.
    4. Name: your subdomain.
    5. Value: fallback.app.avcodex.com.
    6. TTL: 1 Hour.

    Namecheap#

    1. Go to Domain List > Manage.
    2. Click Advanced DNS.
    3. Add new record:

    - Type: CNAME - Host: your subdomain - Value: fallback.app.avcodex.com

    Google Domains / Squarespace Domains#

    1. Go to DNS in the sidebar.
    2. Scroll to Custom records.
    3. Create new record:

    - Name: your subdomain - Type: CNAME - Data: fallback.app.avcodex.com

    Route 53 (AWS)#

    1. Go to Hosted Zones > your domain.
    2. Click Create Record.
    3. Record name: your subdomain.
    4. Record type: CNAME.
    5. Value: fallback.app.avcodex.com.

    Check DNS Propagation#

    Use these tools to verify your DNS is configured:

    Enter your full domain (e.g. chat.yourintegrator.com) and confirm CNAME records point to fallback.app.avcodex.com.

    Test Your Domain#

    Once DNS propagates:

    1. Visit your custom domain in a browser.
    2. You should see your AVCodex agent.
    3. Check the SSL certificate (padlock icon).

    "Could not find CNAME record"#

    1. Wait for propagation: DNS can take up to 48 hours (usually minutes).
    2. Check record type: Must be CNAME.
    3. Check target: Should be exactly fallback.app.avcodex.com.

    "CNAME record does not match"#

    Your CNAME is pointing somewhere else. Update it to point to fallback.app.avcodex.com.

    "Custom domain is already in use"#

    Another AVCodex agent is using this domain. Each domain can only be used by one agent.

    Domain Not Working After Adding#

    1. Remove proxy: If using Cloudflare, disable proxy (use DNS only).
    2. Check DNS: Verify the CNAME target is correct.
    3. HTTPS required: Access via https://, not http://.

    To remove a custom domain:

    1. Go to Settings.
    2. Click the trash icon next to your domain.
    3. Your agent reverts to the default your-agent.app.avcodex.com URL.

    After removing, also delete the DNS record at your registrar.

    Subdomain Naming#

    Pick a subdomain that maps to how AV pros and clients will think about it:

    Good Why
    chat.integrator.com Clear, generic
    roomhelp.brand.com Aimed at end users in conference rooms (works well on QR-code support stickers)
    ai.integrator.com Short, memorable for internal teams
    support.brand.com Reads as a managed-services offering
    programmer.integrator.com Internal tool for AV programmers and field techs

    Backup Access#

    Keep your default your-agent.app.avcodex.com URL bookmarked as a backup in case of DNS issues.
