API integrations that just work — and don't leak your keys.
Connect CRMs, payment gateways, calendars, email tools, custom back-ends. Server-side, secure.
Your website rarely lives alone — it needs to talk to your CRM, your payment processor, your email tool, your calendar. We build those integrations server-side and secure, so they just work and your keys never leak.
Common integrations we build
Contact form → CRM (HubSpot, Salesforce, Pipedrive, Copper, Airtable). Payments → Stripe, PayPal, Klarna, regional gateways. Email → Mailchimp, ConvertKit, Klaviyo, ActiveCampaign. Booking → Calendly, Cal.com, Google Calendar, custom availability. SMS → Twilio, Vonage. Custom → your own internal API.
How we do it right
Keys stored in .env or server-side secrets, NEVER in client JavaScript. Rate limiting at the WordPress or Next.js layer. Retry-with-backoff on transient failures. Webhook signature verification on incoming events. Idempotency keys on writes. Structured logging so failures are visible, not silent.
What we won't do
Ship an integration that puts your API key in browser JavaScript. Skip HTTPS verification because "it's just testing." Store PII in localStorage. Use a third-party API without an error path when it's down. Basic security hygiene.
The integrations we build most
Form-to-CRM (HubSpot, Salesforce, Pipedrive, Airtable). Payments (Stripe, PayPal, regional gateways). Email platforms (Mailchimp, Klaviyo, ConvertKit). Booking (Calendly, Cal.com, Google Calendar). SMS (Twilio). And custom — your own internal API that nothing off-the-shelf knows how to reach. If it has an API, we can wire your site to it.
Security is the whole job
The difference between a good integration and a dangerous one is where the secrets live. We keep API keys server-side, never in browser JavaScript. We verify webhook signatures, add retry-with-backoff for flaky third parties, use idempotency keys so a double-click doesn't double-charge, and log failures so they're visible instead of silent.
What we refuse to do
Put your secret key in front-end code. Skip HTTPS verification because it's 'just testing.' Store customer data in localStorage. Call a third-party API with no fallback for when it's down. These aren't nitpicks — they're the exact shortcuts that turn into breaches and outages. We don't take them.

Often paired with api integrations
Questions people ask about api integrations
Is it safe to connect my site to Stripe/HubSpot/etc.?
Yes, when it's done server-side with keys stored as environment secrets — which is how we build every integration. The danger is only in amateur setups that expose keys in the browser.
What happens if the third-party API goes down?
We build retry-with-backoff and a sensible fallback so a temporary outage doesn't lose your data or crash your site. Failures get logged so you know they happened.
Can you integrate a service that isn't on your list?
Almost certainly. If it has a documented API or webhooks, we can connect it. The list is just the common ones.
Will you document the integration for my team?
Yes — you get documentation covering how it works, where the keys live, and what to check if something breaks.
