Integrations
Pre-auth connects to your payment provider, your phone system, and your messaging tools. No new payment relationships to set up — we add pre-authorisation and card-on-file workflows on top of the infrastructure you already have.
Payment providers
Pre-auth doesn't process payments itself. We integrate with your existing payment provider, so there's no new merchant account to set up and no change to your payment relationship. All card data is handled entirely by your acquirer — Pre-auth just orchestrates the flow.
Full Stripe Connect integration. Pre-authorise, capture, release, save cards on file, and charge tokens — all through your Stripe account.
Pre-authorisation and card-on-file support via Adyen.
Integration with Worldpay for pre-authorisation workflows.
Pre-authorise and manage holds through your Square account.
Don't see your payment provider? Get in touch — we're actively expanding our integrations and can prioritise based on demand.
Communications
Pre-auth can send payment links via email, SMS, or through your existing messaging and phone workflows — so you can secure a booking in the moment, while the customer is still engaged.
Incoming calls automatically surface in your Pre-auth dashboard. See the caller's number, match them to an existing customer, and create a pre-authorisation — all while you're still on the line.
Already chatting with a customer? Incoming WhatsApp messages can trigger contact creation in your dashboard. Send a secure payment link directly in the conversation.
Send payment links via email or text directly from your dashboard. Customers receive a clean, branded link that works on any device — no app download required.
API
For businesses that want to integrate Pre-auth into their own systems, we provide API keys that let you trigger pre-authorisations, manage customers, and handle inbound contacts programmatically.
Push phone calls, messages, or booking requests from any source into Pre-auth via a simple API call. Customer numbers are matched automatically, and contacts appear in your dashboard in real time.
Use API keys to connect Pre-auth to your CRM, booking system, or custom tooling. Automate pre-authorisation creation based on new bookings, calendar events, or any trigger you define.
Generate and revoke API keys from your dashboard. Keys are hashed and stored securely — the plaintext is shown once at creation and never again.
