Need a custom integration?
Custom integrations are a common scope for our agents and skills practice. If your stack includes something not listed here and you need GDK Digital products to connect to it, start a conversation.
Frequently asked questions
Which GDK Digital products integrate with each other?
Fortilis and FTC integrate directly for secure artifact sharing. All GDK Digital
products share a universal login at gdkdigital.com/login.html and a
unified entitlements model. Cross-product workflows are planned and ship per the
changelog.
Can GDK Digital products integrate with my existing stack?
Most products integrate with industry-standard tools: Stripe for billing, Google Workspace and Microsoft 365 for calendar and email, Twilio and WhatsApp Business for messaging, QuickBooks for accounting. For deeper or custom integrations, we can scope a build through our agents and skills practice.
Do you offer a public API?
Each product has an internal API used by its frontend. Public, externally-documented APIs are on the roadmap and not yet generally available. Contact us if you have a specific integration use case and we will tell you what's currently possible.
Can you build a custom integration for my business?
Yes. Custom integrations are a common scope for our agents and skills practice. Start a conversation at /contact and tell us what you need to connect.
Which integrations are paid add-ons versus included?
Most named integrations on this page are included with the relevant product subscription. A few high-cost integrations (Twilio voice, WhatsApp Business, voice-AI providers) require your own provider account because their pricing is metered. Specific pricing per plan is shown in the admin panel for each subscription.
