Streamlining Customer Credits with HQ Rental Software’s API: A Practical Guide

If you handle adjustments, refunds, or goodwill balances, you know how quickly manual credit tracking can slow your team and frustrate customers. Streamlining Customer Credits with HQ Rental Software’s API gives you a reliable way to automate credit workflows, reduce errors, and deliver faster resolutions—without juggling spreadsheets or ad‑hoc processes.

In this guide, you’ll learn what customer credits are, which API capabilities are available in HQ Rental Software, how to authenticate securely, and how to design a simple, scalable implementation that fits your rental operations.

What are customer credits—and why automate them?

Customer credits are amounts you hold on behalf of a customer that can be used to offset future charges. In rental operations, credits commonly arise from billing adjustments, returned deposits, or service recovery gestures. When managed well, credits improve customer satisfaction and shorten the time it takes to resolve billing questions.

Automation matters because it:

• Eliminates repetitive back‑office work
• Minimizes data entry errors
• Creates a traceable history of credit transactions
• Accelerates customer communications and resolution times

Customer Credits in HQ Rental Software’s API

HQ Rental Software provides dedicated endpoints to manage the full lifecycle of customer credits. You can:

• List all credit transactions
• Create a customer credit
• Update a customer credit
• Delete a credit transaction

These operations let you build end‑to‑end workflows—from initial issuance to eventual reconciliation—directly within your applications, portals, or back‑office automations.

Use these capabilities on their own or alongside related areas of the platform such as Payment Gateways, Invoices, and Emails to align credits with your billing and communications workflows.

Secure authentication and regional base URLs

Before you can manage credits, set up secure API access.

How to authenticate

1. Get your Tenant Token: Settings > Integrations > Api Token.
2. Generate a User Token: Settings > Users > open the user’s details > Generate new token.
3. Create the authentication token: Concatenate tenant_token:user_token, then Base64‑encode the result.
4. Send with every request: Use the header Authorization: Basic {AUTHENTICATION_TOKEN}.

This approach allows the API to validate both your company context and the acting user for each request.

Choose the correct regional base URL

Use the base URL for your hosted region when calling the API:

Selecting the right regional endpoint helps ensure consistent performance and correct routing for your environment.

Implementation blueprint: From zero to automated credits

Use the following phased approach to integrate customer credits into your operations.

Phase 1: Foundations and data model

• Define your credit triggers: Identify when to issue or adjust credits (e.g., policy‑based adjustments or post‑rental assessments).
• Normalize metadata: Decide which fields you’ll track for each credit (reason, source event, and any internal references) so that list and audit views remain consistent.
• Prepare authentication: Set up Tenant and User Tokens and confirm regional base URL connectivity.

Phase 2: Core operations

• List existing credits: Use "List all credit transactions" to populate customer profiles, dashboards, or back‑office queues.
• Create credits: Call "Create a customer credit" after your business rules determine a credit is warranted.
• Update credits: If a policy changes or an amount needs correction, "Update a customer credit" to keep records accurate.
• Delete erroneous entries: Use "Delete a credit transaction" to remove duplicates or test data as needed by your governance policy.

Phase 3: Align with billing and communications

• Payment Gateways: Leverage payment‑related endpoints (e.g., listing and creating payment transactions or processing refunds) to keep financial activity cohesive across your system. If you use in‑person payments, you can also work with Stripe Terminal connection tokens provided by the platform.
• Invoices: Use available invoice operations—such as creating or updating invoice items and payments, attaching payments, sending invoice emails, and voiding invoices—to keep billing documents synchronized with financial actions.
• Emails: Trigger email templates and send applicable reservation communications so customers stay informed within your existing messaging workflows.

By combining these areas, you maintain a single source of truth across credits, transactions, and customer communications.

How do you manage customer credits with HQ Rental Software’s API? (Answer)

• Authenticate using Authorization: Basic {AUTHENTICATION_TOKEN} built from your Tenant and User Tokens.
• Call the endpoint to List all credit transactions for the customer you’re reviewing.
• When needed, Create a customer credit based on your policies.
• If details change, Update a customer credit to adjust amounts or notes.
• For erroneous records, Delete a credit transaction in line with your data governance.

This flow supports a complete lifecycle from issuance to archival.

Practical tips for a reliable credit workflow

• Maintain a clear reason code for every credit so reporting and audits are simple.
• Use your own id references to trace credits back to originating events (e.g., service tickets or reservation updates) to prevent duplicates.
• Establish a review queue for high‑value credits to add a lightweight approval step.
• Keep your UI state in sync by refreshing lists after create, update, or delete actions.
• Use error‑handling patterns that surface actionable messages to users (e.g., why a request failed and next steps).
• Rotate and store tokens securely, and limit access to only the users or services that need credit permissions.
• Align credit actions with your Invoices and Payment Gateways processes so financial records remain consistent across the board.

Frequently connected capabilities you can explore next

• Payment Gateways: Manage payment methods, list and create payment transactions, and process refunds. If you support on‑premise checkouts, you can obtain connection tokens for Stripe Terminal.
• Invoices: Create or update invoice items and payments, attach payments, send invoice emails, and void invoices when necessary.
• Emails: View applicable templates for a reservation, trigger templates, and send reservation confirmation or contract emails.
• Additional operational areas such as Online Reservations, Fleet Management, Telematics, Booking Engine, and Toll Integration can complement a credit workflow as you scale.

Practical takeaways

• HQ Rental Software’s API includes dedicated operations to list, create, update, and delete customer credits—everything you need to automate the lifecycle.
• Secure access is straightforward: combine Tenant and User Tokens, Base64‑encode, and send via the Authorization header using the proper regional base URL.
