Connect to
what you already use
Most "integrations" you'd pay extra for elsewhere ship as built-in apps in EternalEngine — payments, email, storage, identity. The ones that don't yet are listed below, honestly marked as roadmap.
Native — no integration needed
These ship as part of EternalEngine. No third-party account, no separate billing, no glue code.
Payment Processing
PayGate ships on every paid plan with a Free tier (3.4% + $0.30 all-in per card transaction) and optional paid tiers ($49 Growth, $149 Scale) for lower fees and higher volume caps. Hosted checkout, subscriptions, payouts, dispute tracking — all in-app, no third-party connect required.
Email Delivery
PostFrame handles transactional + marketing email with SPF/DKIM/DMARC, opens, clicks, templates, webhooks. Optionally bring your own SES, SendGrid, Mailgun, or Postmark.
Google + Outlook Calendar feed
BookSlot publishes a subscribable iCal (.ics) feed of your appointments that Google Calendar, Outlook and Apple Calendar read, so every booking lands on the calendar your team already opens. Two-way sync is on the roadmap below.
Cloud File Storage
AssetVault is real S3-compatible cloud storage with folders, version history, tagging, multipart uploads, and tenant-isolated access. No external GDrive or Dropbox required.
REST API & Webhooks
Every app exposes a versioned REST API with schema-validated inputs, structured logging, and tenant-scoped access. Webhooks fire on key events such as a paid invoice, a booked appointment or an accepted estimate — the way to connect a system we don't list.
SSO — SAML 2.0 / OIDC
Sign in through your identity provider — Okta, Microsoft Entra ID (Azure AD), Google Workspace, Auth0, JumpCloud, or any SAML 2.0 / OIDC provider. Sessions, roles and permissions stay enforced in EternalEngine; SCIM provisioning is on the roadmap.
Native connections coming next
In active development. Visible in the in-app store with full marketing copy from day one — install opens as each ships.
Two-way sync invoices, expenses, and chart-of-accounts data with TitanLedger.
5,000+ third-party apps via Zapier and Make. EternalEngine triggers + actions across the whole catalog.
Surface deal events, invoice payments, project milestones, and AI alerts to your team channels.
Mirror AssetVault folders to your existing cloud storage so your team can access files from familiar tools.
SMS campaigns and notifications via TextCast — bring your own Twilio account or use bundled credits.
Migration helpers + ongoing sync for teams running ClientForge alongside legacy CRMs during the cut-over.
Two-way calendar sync for BookSlot, Drive sync, Gmail/Outlook send-as, Workspace contact sync, and SCIM user provisioning.
Automated sales tax calculation in TitanLedger invoices for multi-state and multi-country billing.
