LawPay Integration: Automated Legal Billing & IOLTA Trust Account API Sync
Eliminate billing friction and guarantee 100% State Bar IOLTA compliance. We build secure API middleware connecting LawPay with GoHighLevel, Clio, SmartAdvocate, Monday.com, and custom client portals.
IOLTA Trust Separation
Commingling of Funds
Level 1 Tokenization
CRM Ledger Settlement
Strict IOLTA Trust Routing
Automatically route retainers and unearned client deposits to Trust accounts while debiting transaction fees separately from Operating accounts.
Automated Retainer Links
Trigger personalized, pre-populated LawPay payment links via SMS and email immediately when a retainer agreement is signed in your CRM.
Instant Invoice Settlement
Payment completion webhooks write back directly to Clio Manage, SmartAdvocate, or GoHighLevel ledgers, marking bills paid and logging transaction IDs.
Why Law Firms Cannot Use Standard Payment Gateways
Most standard merchant payment systems (Stripe, Square, PayPal) deduct processing interchange fees directly from incoming settlements. If a client deposits a $5,000 retainer into your trust account and Stripe deducts $145.50 in credit card processing fees, only $4,854.50 enters the trust ledger.
Under ABA Model Rule 1.15 and state disciplinary rules, this constitutes an immediate ethics violation (shorting client funds and commingling operating obligations with trust funds). LawPay solves this by guaranteeing 100% of client deposits enter the trust account intact while debiting processing fees exclusively from operating accounts.
However, without a dedicated integration bridge, legal staff waste hours manually generating payment links, copy-pasting transaction IDs, and cross-checking bank portals. Our integration automates the entire lifecycle while preserving complete IOLTA compliance.
LawPay / AffiniPay API Integration Architecture
We deploy custom webhook listeners and REST endpoints interfacing with the LawPay (AffiniPay) API. Our middleware validates HMAC signatures, routes to the designated gateway ID, and synchronizes transaction receipts to your CRM ledgers.
- Gateway ID Isolation: Ensures all retainer requests are locked to the firm's Trust merchant ID, preventing accidental operating account routing.
- HMAC Webhook Verification: Cryptographically validates webhook signatures on `charge.completed` events prior to writing to accounting ledgers.
- Automated PDF Receipt Filing: Retrieves digital settlement receipts from LawPay and files them directly in the matter document folder.
High-Impact LawPay Billing Automations
1. Agreement Signed to Payment Link
The instant a fee agreement is signed in GoHighLevel or DocuSign, LawPay generates a secure payment link dispatched immediately via SMS and email.
2. Bi-Directional Clio & SmartAdvocate Sync
Settled transactions update matter bills, apply trust credits, and record reconciliation IDs across Clio Manage and SmartAdvocate accounting ledgers.
3. Evergreen Retainer Replenishment
When trust balance falls below the minimum required balance, the system automatically dispatches an evergreen replenishment invoice to top up client funds.
4. Card-on-File Tokenization
Securely tokenizes client payment credentials using LawPay Vault for monthly legal retainers, recurring installment plans, and authorized subscription billing.

Frequently asked questions about LawPay integration
Standard merchant processors (like Stripe or PayPal) deduct processing and interchange fees directly from the gross transaction amount, which violates State Bar rules if drawn from client trust accounts. LawPay separates deposits from processing fees: 100% of client retainer funds land in your Trust (IOLTA) account, while all transaction fees are billed separately to your firm's Operating account.
Yes. When a prospective client signs a fee agreement in GoHighLevel, Clio Grow, or DocuSign, our middleware calls LawPay's API to generate a personalized, pre-filled trust payment link. The link is automatically dispatched via SMS and email with payment instructions, accelerating retainer turnaround time from days to minutes.
Yes. We configure webhook listeners for LawPay payment completion events (`charge.completed`). When a client pays, our middleware updates the client's matter balance, marks the invoice or retainer deposit as paid, applies the ledger credit, and moves the CRM pipeline stage to 'Retained & Paid' without staff intervention.
Yes. We can automate evergreen retainer workflows. If an attorney's billable hours or expense disbursements pull a client's trust balance below the contractual minimum threshold (e.g. $2,500), our system automatically calculates the replenishment deficit and issues an automated LawPay invoice to top up the retainer.
100% compliant. No raw credit card numbers or sensitive banking data ever touch your servers or CRM database. Our integration leverages LawPay Hosted Fields and secure payment tokens, maintaining complete PCI-DSS Level 1 compliance.
Our LawPay integrations are designed to adhere to the trust accounting guidelines of all 50 U.S. State Bar associations, including California (Rule 1.15), New York (Rule 1.15), Florida (Rule 5-1.1), Texas (Rule 1.14), Illinois (Rule 1.15), and the American Bar Association (ABA Model Rule 1.15).
