A website integration connects the site to another system so information or actions can move between them. Common examples include sending enquiries to a CRM, taking payments, synchronising bookings, adding newsletter subscribers, recording conversions and displaying stock. The visible form or button may be simple, but the business rules behind it rarely are.
This website integration checklist for Malta businesses helps owners and project teams define those rules before development begins. It focuses on practical decisions, testing and ownership rather than a particular plugin or software brand.
1. Start with the business outcome
Describe what the integration must achieve in plain language before discussing APIs or plugins. “Connect the CRM” is too broad. A useful requirement might be: when a visitor submits the corporate enquiry form, create or update the correct company and contact, record the source page, assign the lead by service line and notify the sales owner.
- What event starts the process?
- What information must move?
- Which system becomes the source of truth?
- What should happen automatically?
- What result should staff and customers see?
2. Inventory every system involved
List the website, hosting environment, CRM, email platform, payment provider, booking system, accounting software, analytics tools and any middleware. Record the account owner, subscription level, support contact, test environment and technical documentation for each one.
Do not assume a service supports the required connection because it advertises an integration. Features can differ by plan, region or product edition. Confirm the exact operation needed, such as creating a contact, reading availability, updating an order or sending a refund status.
3. Map fields and formats
Create a field map showing where each value originates and where it is stored. Include names, email addresses, telephone numbers, company details, consent choices, product identifiers, appointment times, currencies and campaign information.
- Define which fields are mandatory and which are optional.
- Agree formats for dates, telephone numbers, countries and currencies.
- Document allowed values for dropdowns and status fields.
- Decide how duplicates are recognised and merged.
- Identify values that must never be overwritten.
A field map prevents small mismatches from becoming operational problems. For example, one system may expect “Malta” while another uses “MT”, or a booking tool may store local time while another records Coordinated Universal Time.
4. Define the direction and timing of data flow
Specify whether information moves from the website to the external system, from the external system to the website or in both directions. Then decide whether the update must happen immediately, on a schedule or after manual approval.
Real-time connections can improve the customer experience, but they also create dependencies. A scheduled synchronisation may be more resilient for non-urgent catalogue or reporting data. Choose the timing according to the business consequence of delay.
5. Choose the integration method deliberately
Common approaches include a supported plugin, a native connector, an automation platform, direct API development or a scheduled file exchange. Compare them on reliability, security, flexibility, monitoring, ongoing cost and the ability to change supplier later.
WordPress provides a REST API that applications can use to send and receive structured data. Where an authenticated connection is required, credentials and permissions must be designed for the specific use case rather than shared casually between administrators and services.
6. Assign ownership of accounts and credentials
The business should know who owns each account, billing relationship, API credential, webhook endpoint and automation workspace. Avoid building a critical process inside a developer’s personal account or a staff member’s private email address.
- Use business-controlled accounts and role-based access.
- Give each integration only the permissions it needs.
- Store secrets in an appropriate protected location, not page content or shared documents.
- Record how credentials are rotated and revoked.
- Include ownership in the website handover checklist.
7. Apply security controls to every connection
An integration expands the website’s technical boundary. The OWASP API Security project highlights risks including broken authentication, weak object-level authorisation, unrestricted resource consumption and unsafe consumption of third-party APIs. The project team should consider these risks during design and testing, not only after launch.
Use encrypted connections, restrict permissions, validate incoming data, avoid exposing unnecessary fields and log security-relevant events. Rate limits and sensible timeouts can reduce the impact of abusive or faulty requests.
8. Build privacy requirements into the data flow
Record what personal data moves, the purpose, destination, retention and parties involved. The European Data Protection Board advises organisations to implement data protection by design and by default and to limit personal data to what is necessary.
The integration inventory should feed into the privacy notice, supplier review and records of processing. The website privacy and cookie checklist provides a wider review of forms, tracking, consent, retention and ongoing governance.
9. Define validation and business rules
State what happens when information is missing, malformed or inconsistent. Decide whether the website blocks submission, requests a correction, accepts the record for manual review or continues with a safe default.
- Can an enquiry be created without a company name?
- Can a booking be confirmed if payment is still pending?
- What happens when a product code does not exist in both systems?
- Which system decides availability, price or customer status?
- Who can override an automated decision?
10. Plan for duplicates and repeat events
Networks retry, users double-click and external services can deliver the same event more than once. The process should avoid creating duplicate orders, charging twice or opening repeated CRM records.
Stripe’s official webhook guidance, for example, recommends handling duplicate events and listening only for the event types an integration needs. Even when another platform is used, the underlying lesson is valuable: design repeat processing to produce a safe, predictable result.
Document the fallback for timeouts, maintenance windows and supplier outages. A contact form may store an enquiry safely for later delivery, while a payment or appointment request may need a clear message and no confirmation until the external system responds.
- How many times should the action be retried?
- Where are failed items queued?
- Who receives an alert and how quickly?
- Can staff complete the task manually?
- How is the customer prevented from receiving a false confirmation?
12. Create a realistic test environment
Use test accounts, sandbox credentials and non-production data where available. Test successful transactions as well as declined payments, unavailable slots, duplicate records, invalid fields, expired credentials, delayed responses and interrupted network requests.
Agree acceptance scenarios in the website development brief and run them as part of the pre-launch website testing checklist. The person who owns the business process should confirm the result, not only the developer who built the connection.
13. Verify analytics and conversion tracking
Decide which completed event represents a genuine business outcome. A button click is not the same as a successful payment, confirmed appointment or accepted enquiry. Where appropriate, send the confirmed outcome from the system that knows it happened.
Use consistent campaign parameters and identifiers so leads or transactions can be matched without exposing unnecessary personal data. Document how test activity is excluded from business reporting.
14. Monitor the integration after launch
A connection can fail quietly after a password change, plugin update, field edit or supplier API change. Monitoring should cover both technical success and business completeness.
- Track failed requests, rejected records and delayed queues.
- Reconcile website submissions with destination records.
- Alert an identified owner when thresholds are exceeded.
- Review credentials, permissions and unused connections.
- Retest after relevant website or supplier changes.
Add these tasks to the website maintenance schedule and keep a short change record showing what was altered, tested and approved.
15. Prepare an integration handover pack
The handover should explain the purpose, systems, field map, data direction, credentials owner, permissions, error handling, alerts, test cases, support contacts and renewal costs. Include instructions for disabling the connection safely and recovering queued work.
This documentation reduces dependence on one developer and gives future suppliers a reliable starting point. It also helps the business assess the effect of changing its CRM, payment provider or booking system.
Questions to include in a website proposal
- Which integrations are included, and which require separate supplier fees?
- Is the connection native, plugin-based, middleware-based or custom?
- Who owns the accounts, code, automation and documentation?
- Which success, failure and security scenarios will be tested?
- How are failures monitored and supported after launch?
- What happens if a third-party service changes or is replaced?
Plan integrations before development starts
The best time to define an integration is before layouts and forms are finalised. A clear process map, field map and acceptance test can prevent expensive rework and unreliable manual workarounds.
