Step 3: Assess Tool Integration & API Availability

This is one of the largest problems we find: tools don't correctly talk to each other. This step helps you understand how your tools connect (or don't) and why API availability is critical.

The Integration Problem​

The Core Issue:

  • Tools don't correctly talk to each other
  • Data silos: information trapped in individual tools
  • Manual workarounds: copying data between systems
  • Incomplete customer journey visibility
  • Duplicate data entry wasting time

Why It Happens:

  • Tools purchased without considering integration
  • Built-in integrations are limited or don't work properly
  • No API access means no programmatic connection
  • Tools from different vendors don't communicate
  • Integration complexity increases with more tools

The Cost of Poor Integration:

  • Time wasted on manual data entry
  • Errors from manual processes
  • Incomplete reporting and analytics
  • Missed opportunities from data gaps
  • Team frustration and inefficiency

Understanding APIs (Application Programming Interfaces)​

What Is an API?

API = Application Programming Interface. It allows tools to programmatically talk to each other. Think of it as a "translator" between tools that enables automated data sharing between systems.

Why APIs Matter:

  • Programmatic Connection: Tools can automatically share data
  • Real-Time Sync: Data updates across all tools instantly
  • Automation: Eliminates manual data entry
  • Custom Integrations: Build exactly what you need
  • Future-Proof: Can adapt as your needs change

Without APIs:

  • Limited to built-in integrations (if they exist)
  • Manual data export/import
  • No real-time sync
  • Can't build custom workflows
  • Stuck with vendor's integration options

How to Check API Availability​

For each tool, check:

API Documentation​

  • Does the tool have API documentation?
  • Is it publicly available?
  • How comprehensive is it?
  • Is it actively maintained?

API Access Requirements​

  • Is API access included in your plan?
  • Do you need a higher tier for API access?
  • Are there API rate limits?
  • What's the cost for API access?

Integration Capabilities​

  • What built-in integrations exist?
  • Do they work reliably?
  • Can you build custom integrations?
  • What automation platforms support it? (Zapier, Make, N8N)

Data Export/Import​

  • Can you export data easily?
  • What formats are supported?
  • Is there an API for programmatic access?
  • Can you import data from other tools?

Mapping Your Current Integrations​

Create an integration map. For each tool, document:

  1. Connected Tools: What other tools does it connect to?
  2. Connection Type:
    • Native integration (built-in)
    • API-based (programmatic)
    • Manual (export/import)
    • No connection
  3. Data Flow: What data is shared? (contacts, events, analytics, etc.)
  4. Sync Frequency: Real-time, hourly, daily, manual?
  5. Reliability: Does it work consistently?
  6. Issues: What problems exist?

Example Integration Map:

HubSpot (CRM)
├── Gmail → Native integration (works well)
├── Slack → API-based (reliable)
├── Mailchimp → Manual export (problematic)
└── Google Analytics → No connection (data silo)

Mailchimp (Email)
├── HubSpot → Manual export (time-consuming)
├── Shopify → Native integration (works)
└── Google Analytics → No connection

Identifying Integration Problems​

Red Flags:

  • Manual data copying between tools
  • Data inconsistencies across systems
  • Duplicate data entry
  • Tools that don't connect at all
  • Built-in integrations that don't work properly
  • No API access for critical tools
  • Data silos (information trapped in one tool)

Common Integration Issues:

  • No API Access: Tool doesn't offer API or it's on expensive tier
  • Limited Integrations: Only connects to a few popular tools
  • Unreliable Sync: Integrations break or don't update properly
  • Data Format Mismatch: Tools use different data structures
  • Rate Limits: API calls are limited, causing delays
  • Complex Setup: Integration requires technical expertise

The API Requirement Checklist​

When evaluating tools, ask:

Critical Questions:

  1. Does this tool have an API? (Essential for programmatic connections)
  2. Is API access included in our plan? (Check pricing tiers)
  3. What can the API do? (Read data, write data, both?)
  4. What are the rate limits? (How many API calls per minute/hour?)
  5. Is the API well-documented? (Can developers use it easily?)
  6. What automation platforms support it? (Zapier, Make, N8N, etc.)
  7. Can we build custom integrations? (Or are we limited to built-in options?)

Decision Framework:

  • Must Have API: Core tools (CRM, email, analytics)
  • Should Have API: Important tools (automation, forms, chat)
  • Nice to Have API: Supporting tools (design, project management)

Integration as a Cost Factor​

Hidden Costs of Poor Integration:

  • Time Cost: Manual data entry (hours/week)
  • Error Cost: Mistakes from manual processes
  • Opportunity Cost: Missing insights from data silos
  • Tool Cost: Paying for multiple tools that should share data
  • Support Cost: Fixing integration issues

Example:

  • Company spends 5 hours/week manually syncing data between HubSpot and Mailchimp
  • At £50/hour = £250/week = £13,000/year in time cost
  • Solution: Use API to automate sync = £0 ongoing cost (after setup)

Integration Audit Checklist​

For your stack audit, add:

  • Does each tool have API access?
  • What tools are currently connected?
  • How do they connect? (Native, API, manual)
  • Are integrations working reliably?
  • What data is shared between tools?
  • Are there any data silos?
  • What manual processes exist?
  • Which tools should connect but don't?

Integration Priority:

  1. Critical: Core tools must connect (CRM ↔ Email ↔ Analytics)
  2. Important: Supporting tools should connect (Forms → CRM, Chat → CRM)
  3. Nice to Have: Optional connections (Social → Analytics)

When to Prioritise Integration Over Cost​

Sometimes integration value > cost savings.

Example Scenario:

  • Tool A: £100/month, no API, limited integrations
  • Tool B: £150/month, full API access, connects to everything
  • Decision: Pay £50/month more for Tool B because:
    • Saves 10 hours/month in manual work = £500 value
    • Eliminates errors from manual processes
    • Provides complete data visibility
    • Enables automation and future growth

Rule of Thumb:

  • If integration saves significant time → worth paying more
  • If tool doesn't integrate → consider alternatives
  • API access is often worth the extra cost for core tools
